:: Flow Meters

Coriolis Meters
Identifying flow rates by directly measuring fluid mass over a wide range of temperatures with a high degree of accuracy, Coriolis Mass Flow Meters are suitable for a variety of fluids such as slurries and other viscous, nonconductive fluids. Coriolis meters are ideal when a high level of accuracy is necessary and for applications where measurement is difficult with other technologies.
Differential Pressure Flow Meters
Differential Pressure (DP) flow meters introduce a constriction in the pipe that creates a pressure drop across the flow meter. This technology is suitable for applications including DP measurement across filters, heat exchangers, backflow preventers, pipelines, ducts and more.
Electromagnetic Flow Meters
Electromagnetic Flow Meters manage critical flow applications to improve accuracy, decrease system maintenance and meet the demands of challenging liquid conditions. This volumetric flow meter does not have any moving parts and is ideal for wastewater applications or any dirty liquid that is conductive or water-based.
Positive Displacement
Positive displacement flowmeter technology is the only flow measurement technology that directly measures the volume of the fluid passing through the flowmeter. Positive displacement flowmeters achieve this by repeatedly entrapping fluid in order to measure its flow. This process can be thought of as repeatedly filling a bucket with fluid before dumping the contents downstream. The number of times that the bucket is filled and emptied is indicative of the flow through the flowmeter. Many positive displacement flowmeter geometries are available.
Turbine Meters
Turbine flow meters use the mechanical energy of the liquid to rotate a rotor in the flow stream. The rotational speed of the rotor is directly proportional to the velocity of the fluid travelling through the meter. These meters are used in multiple industries to reliably measure the velocity of a variety of liquids, gases and vapors.
Ultrasonic Flow Meters
Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter technologies: Doppler shift and transit-time. Transit-time measures the time differential between signals sent upstream and downstream. The differential is directly proportional to the velocity of the water. Transit-time meters are best used for measuring the flow of clean liquids and, as a result, are the most popular type of ultrasonic meter. Doppler shift measures the difference in frequency of the sound wave reflected off gas bubbles or particles in the flow stream and is suitable for aerated or dirty liquids.
Vortex Flow Meters
Vortex flow meters utilize ultrasonic technology to measure tiny vortices that form when media in the pipe move across a strut, or "bluff bar." The number of vortices formed is directly proportional to flow rate, and the resulting product is a flow meter with high turndown ratio (up to 70:1) and high accuracy (±1% of reading).
