METERS, a type of INSTRUMENTATION.
Meters are a type of Instrumentation.
This subcategory covers flow measuring devices, including several types of mass flowmeterssuch as multi?parametric, thermal and Coriolis instruments. Primary elements used in flow measurement include orifices, plates, nozzles, Venturi tubes, Pitot tubes, fittings, flanges and meter runs. Ultrasonic flow meters are also part of this subcategory and include both Doppler and transit?time versions. A rotameter is another name for a variable area flowmeter.
Mass flow controllers integrate a mass flow meter, electronic controls and a valve. Data loggers are included, regardless of whether they transmit flow data or other types of data, and flow computers are encompassed here due to their association with flow measurement.
