Precision Air Flow Measurement Without the High Cost

Eastern Instruments presents the QVT Smart Multivariable Flow Transmitter for air/gas without the high costs typcially associated with DP transmitters.

Eastern Instruments introduces the world to the QVT Smart Multivariable DP Transmitter. The QVT is a Smart Transmitter that can be used for the accurate measurement of up to four separate process variables including Differential Pressure, Temperature and Absolute Pressure. When coupled with any DP based flow measurement element, the QVT will calculate the fully compensated mass flow of air/gas travelling through any process which is at or near atmospheric pressure (5 - 25 psia). The typical operating range of the QVT is between 0.0009 and 9.9 in WC (1000:1). Its high accuracy, especially at such low flow rates, is due in part to its unique process seal which requires no diaphragm seal. Due to condensate, diaphragm seals often cause inaccuracies in alternate technology’s sensor readings.
