Flow rate is determined by measuring the pressure drop across a laminar flow element, where the flow rate is linearly proportional to any change in pressure
The PV series flowmeter measures the flow rate of non-hazardous, inert gases with an accuracy of +/-2% of full scale.
The standard output is 0-5 VDC; the meter is also available with a 4-20mA output signal, integral display or remote digital display.
The PV Series flowmeter is available with full-scale ranges from 50CCM to 50LPM with 50:1 turndown.
All units are supplied with an aluminum body, polycarbonate case and brass compression fittings.
The flow rate is determined by measuring the pressure drop across a laminar flow element.
As gases move through the flow element, the flow becomes laminar; as a result, the flow rate is linearly proportional to any change in pressure.
This creates a highly accurate volumetric flow rate output, which can be displayed or transmitted as an analog signal.
The major advantage of this technology is no moving parts, which means a long, dependable life for the meter.
