Flowmeters

Flowmeters measure the volumetric or mass flow rate of liquids, gases, and steam in pipes and ducts. They are essential instruments for process control, custody transfer, energy management, and environmental compliance monitoring. Operating on principles ranging from ultrasonic transit-time and Coriolis mass measurement to thermal dispersion and differential pressure, flowmeters are selected based on the fluid type, flow range, required accuracy, and installation conditions.

In industrial and laboratory settings, flowmeters support tasks such as controlling reagent dosing, balancing HVAC air distribution systems, metering fuel and gas consumption, and monitoring cooling water in power generation. Panametrics (Baker Hughes) specializes in ultrasonic clamp-on and inline flow measurement for liquids and gases. TSI Incorporated is a leading supplier of precision gas flowmeters for laboratory and medical applications, while Dwyer Instruments provides air velocity transmitters and flow switches for HVAC and building automation.
