Coriolis Flow Meters are instruments that work using the Coriolis effect as a flow measuring method. In science, the Coriolis effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame. One typical example of this phenomenon is the children story. Consider two children on opposite sides of a spinning roundabout (carousel), who are throwing a ball to each other. From the children's point of view, this path of the ball is curved sideways by the Coriolis effect. From the perspective of the thrower, the deflection is to the right with anticlockwise carousel rotation (viewed from above). Deflection is to the left with clockwise rotation. This[..]

Aircraft instruments are driven by aerospace sensors. Aero engine temperature sensors The thrust indicator measures jetpipe pressure, sensing pressures at inlet and exhaust, pressure sensors. Temperature sensors have a sensing element, a thermocouple, a heat-resistant tube containing two wires of different materials, such as one of nickel-aluminium and one of nickel-chromium. They are joined at the end of the protective tube, which projects into a suitable point in the hot gas. Usually there will be from two to ten thermocouples arranged round the turbine section, plus others to sense the inlet air temperature. Each pair of wires is joined again inside a cool box, and it is the[..]

Is using a tire pressure gauge enough to ensure that your tires maintain their recommended tire pressure? Well, that depends on whether you use it or not. If you use it, the answer is yes. If you don't use it, the answer is no. I know from experience that not using your tire gauge is not only stupid, but dangerous. I used to travel a lot in my job as a territory manager and although I had my car serviced on a regular basis, a tire leak can be something that the best car service providers may not be able to detect. The result of that was that I had a blowout zipping down the Interstate at 75 miles per hour on a Friday afternoon. I had been on the road all that week and was headed home.[..]

In today’s society there are plenty of forms of noise all around us. That can be considered a form of pollution if it isn’t kept under control. To help keep society free of such additional noise there are now standards in place regarding it. One way to make sure that everything is in compliance is through acoustic shock and vibration testing. There are plenty of benefits found through such testing. They check for the overall performance of a system, the strength of the foundation, if the system is resistent to shock and vibration, and if all of those noise ordinances are followed. The last thing any business wants is to pay fines for not being in compliance. At the same time acoustic[..]

The new breed of CCTV cameras known as wireless internet CCTV cameras or IP cameras is totally digital, more like a computer than a traditional camera. This new type of camera detects changes in the digital image that its sensor "sees" to decide whether something has moved within the picture. This method of detecting movement can be improved upon by adding a passive infra-red (PIR) sensor to the camera, as this article explains. There is a limitation to using internet CCTV cameras to detect movement. These cameras determine whether movement has occurred within their field of view by examining changes in the digital images that the camera's optical sensor produces. One problem with this[..]

Sensors are wonderful things. Many of us have one by the front door, which turns lights on automatically when we get home late at night. This reassures us that no-one is lurking in the shadows, and gives us enough light so we can see to unlock the door. In the home, sensors provide benefits including convenience, security and cost savings (through having lights on only when required). In commercial buildings, these same benefits are multiplied many times over. Lighting can account for up to 40% of the energy used in commercial buildings, and the cost of that energy is creeping up year by year. One of the easiest ways to reduce energy use and to cut costs (and emissions) is to turn off[..]

A peak flow meter provides a good way to keep tabs on symptoms and airway conditions. This small handheld device measures how much air a child can breathe out. If her airways are starting to swell and tighten with asthma flare, the peak flow reading will drop. Although the peak flow meter is a valuable tool for asthma management, it is not for every-one. Children younger than age five or six usually can't use it. An adult should supervise the use of a peak flow meter until the child is fourteen to sixteen years old. Peak flow meters are inexpensive and available without a prescription at any pharmacy. Ask your doctor or nurse practitioner which type is best for your child. To keep the[..]

Electromagnetic flow meters are used to measure the speed of water flow in water distribution systems and to measure the flow rate of electrically conducting liquids, pastes and slurries (viscosity less than 200 cps).  Electromagnetic flow meters are the ideal option where there is an occurrence of debris or sand which would affect most industrial mechanical flow meters. They work on the physical principle of electromagnetic induction as per Faraday’s law of electromagnetism and factors like temperature, pressure, density and viscosity have no influence on the result. They have low maintenance cost and long life because of the absence of moving parts. Electromagnetic flow meters are[..]

If you own a motorcycle, scooter, ride a bicycle or even drive a mini hybrid car you've probably been frustrated by lengthy waits at traffic lights. Not only is this annoying it's also unnecessarily adding to your journey time, costing you extra fuel and can present an additional risk to the most vulnerable road users. The probable cause for your frustration is the traffic lights controller sensor failing to pick up your smaller vehicle. These 'demand actuated' traffic light sensors are a perfectly sensible way to avoid unnecessary disruption to traffic flow. However that's pretty useless to know if your stuck at the intersection, on your bike waiting for the next truck to pull up to[..]

Next time you visit your doctor for a routine checkup, notice the pressure transducer in his exam room. If you're not sure what that is, just look for the cuff that is put around your arm to check your blood pressure. When you think about it, the science behind checking something as simple as blood pressure is impressive. Each time your heart beats it creates pressure in your blood vessels and they expand slightly. If an object is resting against the blood vessel as it expands then pressure is applied to the object. A blood pressure cuff is a transducer that takes that pressure and measures it, then translates the pressure change into a signal sent up to equipment that reads the signal,[..]

There are many reasons for selecting helical rotors over that of flat-bladed rotors. The helical blade transfers energy more efficiently from the flow stream to the rotor, producing a faster speed of response to flow changes (2-3 mS depending on the rotor mass and blade area). Helical rotors also minimize rotor slip in flow startup or stop, representing more accurately the actual flow rate being measured. This is important if you have a fluid measurement requirement that is cyclic or involves short flow bursts, such as in hydraulic applications. Helical rotors have less fluid force on the bearing, which reduces friction and heat, extending the life of the bearing. When using flat-bladed[..]

Smart Water Meters, which has been launched recently in the market, help in identifying and reporting the water consumption data at various levels. The information captured is transferred to a computer based system through wireless communication. Thus, the information can be used for efficient water planning (water restrictions), distributing water usage in peak times (off-peak, peak), capacity planning, use/time based costing (smart tariffs), and better operations management. The benefits of implementing Smart Water Meters to both the user and utility providers are tremendous. It facilitates faster and more efficient meter reading, theft detection, leaks, remote monitoring, etc, for the[..]

Point of Use (POU) meters are designed to provide a submetering solution for those properties that cannot be submetered by conventional submeters due to plumbing designs that bring multiple pipes into the apartment or office (stacked risers). The meters were specifically designed for stacked riser plumbing configurations typically found in properties that utilize a central boiler to provide hot water. In a typical installation very small flow meters are installed inconspicuously on each hot & cold outlet to the shower/tub, toilet, sink, dish washer and clothes washer. Depending on the manufacturer the flow meters either have a transmitter built in or are connected to an interface[..]

One of the worst things that homeowners choose not to do is never opened up their meter cover. I don't even think most homeowners know where the meter actually is located, but that's going to need to change, starting today. If you don't know where your water meter is located, you could always contact your local utility company, to ask for assistance. Another method, that I like to use, would simply be to walk around the house and look for the meter housing, which is usually located near your streets or alley. You'll be looking for something that says meter on it and it should be even with the ground. Sometimes waters meters are located in sidewalks or driveways, but you need to find out[..]

If you're an enterprising farmer that wants to monitor the rate of water flowing into your fields in order to optimize your yields or to keep an eye on liquid animal wastes flowing out of your farm or run a factory that needs to monitor sewer and liquid wastes in order to[..]

There is a large array of load cells that are available today, all have different specifications and are more suited to certain jobs than others. So how do you know which load cell to use for which application? Here is a look at some of the different load cells that are obtainable, a short description, and which usage they are more appropriate for. Compression Load Cell - DL - load cells are usually described by a range of aspects which people usually want to know such as its range, its overload, and its accuracy. This compression load cell has a range of 50, 100, 150, 250, 500, 1.000, 1.500, 2.000, 3.000, 4.000, 5.000 kg. Its overload capacity is up to 1000%, and its accuracy is[..]

Maintaining proper oil pressure is crucial in the longevity of a car engine. With a forced lubrication system that was invented by Frederick Lanchester, the oil pump picks up the oil and forces it through the drillings or oil galleries into the bearings that are the most highly stressed, like the main bearings, or the big ends and camshaft bearings. Oil jets lubricate the cam lobes, cylinder walls, and other components. Having the right amount of pressure will make sure that the metal of the journal or rotating shaft and the metal of the bearing shell will never touch. This helps reduce wear to only the initial engine start up and shut down. The rotation of the shaft, combined with the[..]

The scuba gauge may appear as a less conspicuous component of an open water scuba set. But then this piece of scuba equipment alerts the scuba diver of remaining tank pressure; to help him estimate the duration of his stay underwater and determine the appropriate time for ascent as well. Note that quality is an important factor in the selection of a scuba gear as the info displayed on its panel is critical to the dive. In this regard, let us take a look at the convenience, adaptability and safety features of the Pony Tank Pressure Gauge from scuba gear maker H2Odyssey. Convenience in a Gauge: The Pony Tank Pressure Gauge is handy enough to pack along with the rest of your gear. Although[..]

The filled system essentially consists of: Pressure tube: This is made up of copper, monel, or stainless steel. It is filled with the liquid or gas or the vapour pressure and the liquid.

Capillary Tube: The capillary tube connects the filled tube with the receiving element. Receiving Element: The receiving element is pressure sensing device and it can be bourdon's tube, bellows or diaphragm. The free end of the bourdons tube is connected to a pointer of temperature calibrated scale. These are generally of 3 types: 1. Liquid 2. Gas and 3. Liquid vapour pressure filled[..]

I often talk about the importance of checking the inflation pressure in tires, but is your tire pressure gauge giving you accurate information? An RVer said, "I understand that tire pressure in an RV is crucial and can cause serious problems if not inflated correctly. Well, the problem is this, how do you know if the tire gauge is accurate? I have seen two tire gauges show as much as 16 psi difference on the same tire. Is there a recommendation as to which tire gauges are the most accurate?" What's funny about this is for many years, as a Maintenance Warrant Officer in the Army, I was responsible for tool calibration programs. Certain tools required regular calibration to ensure[..]

An air pressure gauge is an automotive device used to measure the air pressure inside a vehicle's tires. All vehicle manufacturers have a recommended pressure setting at which the vehicle performs optimally. If you maintain the right air pressure inside your tire, you will help improve the vehicle's fuel efficiency and performance, as well as the life span of your tires. There is a lot of choice when it comes to buying an air pressure gauge. Prices for these devices can range anywhere from $5 to $100, so you must do your research before setting off to buy one. The most inexpensive air pressure gauge is the pencil-type tire pressure gauge. These are very easy to use and consist of a stick[..]

Most swimming pool owners take for granted the significance of one of the simplest gadgets included in their pool equipment, the pressure gauge on the main pool filter. This one instrument is the equivalent of a thermometer to the human body. When the variance from 98.6 is too large, either high or low, we know our body is sick and needs attention. The same rule applies to the pressure gauge on a main swimming pool filter. Used properly it can be a pool owner's best tool to avoid, diagnose, and solve common pool problems. The first key to using the pool filter pressure gauge as the tool it is intended to be is to establish and document a "normal operating pressure". This reading should[..]

A low pressure gauge is a device specifically designed to provide accurate and precise readings of low oil pressure levels in your engine. Not all makes and models of auto are fitted with an oil pressure gauge on the dashboard but those that aren't will still usually have a warning light that first flickers and then shows a constant red light when your oil pressure falls below an acceptable level. If your pressure gauge warning light is flashing, it is an indication that the oil pressure is alarmingly low. Hence, to help you diagnose what is causing the sudden drop on oil pressure, here is some useful information that may assist to locate the problem. A good and simple way to diagnose[..]

Vibration testing is applied to a new product to make sure that it will last the rigors of shipping, handling, and transportation. If you have a product - referred to as the DUT or device under test?a vibration test will expose any potential flaw that your product may have by exposing it to shock. Products that are candidates for random vibration testing include cars, military electronics, and others that are generally subjected to irregular pressure and airflow. Of course, the common problem is trying to know just how much shock should be applied to the DUT. Since the amount of pressure applied during shipping, handling, and transportation does not follow a certain pattern, it would be[..]
