There are many types of flowmeters and flowmeter-related equipment available on the Australian marketplace. These include, but are not limited to, industrial and sanitary turbines, variable area flowmeters, flow transmitters, flow alarms, flow indicators, specialist medical gas flowmeters, multipulse positive displacement flowmeters, batch meters, insertion meters, electromagnetic flowmeters, water meters and irrigation meters. B.E.S. Flowmeters is an Australian firm that has been operational since the mid-eighties. B.E.S. is one of Australia’s leading providers of flow meters, water meters, batching systems and other related forms of instrumentation. They stock only the highest quality...

A standard flowmeter either uses a float or a paddlewheel to measure flow. In order to work, fluid is passed through the flowmeter which either spins the paddlewheel or pushes a float. For installation either you cut into the pipe to attach the flowmeter or you have a branch off to use a floater flowmeter. Ultrasonic flowmeter is different. This flowmeter will work with any sound conducting liquid. The ultrasonic flow meter is placed near the application and two clamp-on "transducers" are placed on either side of the pipe. To detect flow through a pipe, ultrasonic flowmeters use acoustic waves or vibrations of a frequency. Depending on the design there are two ways of measuring flow, either Doppler...

Have you ever needed to test the flow rate of a fluid, but there was no flow meter installed? At times like that, a portable flow meter is extremely useful. A portable flow meter can still measure the flow rate of a fluid with accuracy, but is portable, so one can move it around and test multiple locations. They are made portable because the transducers small and light enough to hold in one hand. Ultrasonic signals in gas flow meters are used because they are non-invasive, that is they do not touch the fluid being measured. They are created to be able to measure many types of fluids, such as oxygen, steam, or diesel. This article will explain the usefulness of a portable ultrasonic gas flow meter...

One of the most difficult flow measurements for the automotive engineer is to measure the engine oil flow rate under operating conditions. With the engine mounted on a test bench and coupled to a dynamometer, the job is slightly easier due to the increased space availability, but none the less, careful selection and installation of the flow measurement system is required. Flow measurements required in the engine bay of a vehicle become further restricted due to instrument power requirement, installation space required and the harsh under bonnet conditions. What are the flowmeter options? Well, industry standards seem to exist to some extent, but this does not mean they are correct. Let us look at...

Introduction One of the most surprising developments in flowmeter technology in the past few years has been the rapid growth in ultrasonic flowmeters. More and more users are recognizing the benefits of the nonintrusive technology that ultrasonic flowmeters offer. Ultrasonic Flowmeter Technology Ultrasonic flowmeters utilize two different technologies: Transit time and Doppler. Both are primarily used for closed pipe applications. Transit time ultrasonic flowmeters have two transducers that send two acoustic signals from one side of the pipe to the other. One transducer is a sending transducer and the other is a receiving transducer. Transit time flowmeters are mainly used on clean liquids. For...

Types of Water Flow Meters Accurately tracking the flow of water is a critical need in many industrial and agricultural operations. The capacity to reliably obtain accurate water flow measurements is so important that it is often the deciding factor between turning a profit and taking a loss and in agricultural applications can mean the difference between having enough water for every need and shortages. In other cases, inaccurate water flow measurements or, worse yet, failure to obtain readings at all can cause serious shortfalls or overages in supply which could potentially send entire commodities markets into a spin. So how is the flow of water measured? Water flow rate is determined...

are a parent of a school going child, you will be bound to be studying along with your child every day. You will have more tension than he/she has when the exams are around the corner and, needless to say, you will know "your" lessons better. Though I consider myself a very straight forward disciplinarian, I could never have the heart of saying no to my son, when he asked me to help him with his studies. What "Help" Means When It Is In Context With Homework The meaning of "help" in the dictionary of a child is very different from what you will find in the Webster's Dictionary. When your child asks for help, if you are wise, you will go and do some overtime in the office. If not, you will find...
