  • The Zero Maintenance Electromagnetic Flowmeter

    Whether a buyer is looking into purchasing an electromagnetic flowmeter for residential use or in an industrial setting such as a wastewater treatment facility, they will be pleased to hear that electromagnetic flowmeters, as well as most other flow meters on the market today, require zero maintenance. This is an astonishing and exciting thing because of where these flow meters are located, within water or other liquid systems that are often difficult to reach. The time consuming process of maintaining an electromagnetic flowmeter is significant, particularly in our society where...

  • The Many Shades of Flow Meters

    The measurement and management of the flow of gas and liquid through a system requires a tool that is safe, effective and long-lasting, particularly when the industry within which it functions is dealing with a toxic substance. Although even with a safe substance, like water pipes, a poorly managed system could burst and flood and do a lot of damage to a company and its workers. This is why flow meters are on the market and working within liquid and gas systems everywhere. The varied industry market and high demand...

  • Controlling the Fluids in Aerospace Crafts

    Precision is a necessity in many industrial settings, and the aerospace industry is no exception. In fact, because of the many factors an aircraft going into space must deal with, knowing exactly how all the elements of the aircraft work together, including the fluids that run it, is even more vital. Control flow meters, which are also known as simply flow meters, play a large role in helping to monitor and control the way these fluids combine, and ensuring the exact balance is always achieved. The highly accurate readings of...

Industry Information


Flowmeters are used to measure the flow of air, fluids and gas. Many flowmeters measure the volume of the material while other flowmeters measure the speed, and still other flowmeters measure the mass of the materials. For the most part, flowmeters are used to infer mass flow through calculations that flowmeters and flow monitor instruments make after taking various flow measurements, such as absolute pressure, differential pressure, viscosity and temperature.

Most flowmeters are made of three parts: the primary device, transducer and transmitter. These three flowmeters parts are usually combined so that the flow meter is one complete instrument. Flow indicators, which are observation windows in industrial processing lines, aid in measuring flow by visual indicators. Flowmeters are useful in a variety of fields. Medically, flowmeters are can be used measure a patient's air intake. In plumbing, flowmeters are used to measure the amount of fluid running through a tube for efficiency purposes. In general, flowmeters are used in many industrial purposes for flow measurements to help companies determine profit gain or loss. Other industries that benefit from the use of flowmeters include automotive, petroleum and gas, utility services, HVAC, food processing and raw materials.

Flowmeter manufacturers offer various instruments for different measurements of flow. Thermal mass flow meters take measurements with two sensors that work together. A temperature sensor reference and an active heated sensor take measurements by calculating how much heat loss occurs in the flowing liquid, and thus these flowmeters can determine the flow rate based on this amount. Another type of flowmeter is the Coriolis mass flow meter, which operates on the basis of the Coriolis Effect. In the Coriolis Effect, an excitation force is applied to the flowmeter tube, causing the fluid or gas to rotate because the acceleration is acting in opposite directions on both sides of the applied force. A flowmeter measurement can then be taken. Other kinds of flowmeters operate using sound. These are called ultrasonic flowmeters, and include several types, like Doppler Effect flow meters and time-of-flight flowmeters. Each type of flowmeter has specific guidelines that must be followed for proper use. For example, when using gas flowmeters, the flowmeters must remain full of gas. Liquid in gas flowmeters can affect the flowmeter's accuracy. Similarly, in order for liquid flowmeters to work properly, they must remain full of liquid. Gas in liquid flowmeters can affect the accuracy of flow meters' readings, as well as contaminants of any kind.
