New electronic flowmeter from Key
The PV Series Flowmeter measures the flow rate of non-hazardous, inert gases with an accuracy of +/-2% of full scale: the meter uses a laminar flow element and achieves a 50:1 turndown

Revolutionary new concept in site monitoring
Food, Pharmaceutical and all manufacturers of perishable products can now protect their process operations against equipment failure without capital outlay and for a little as GBP3 a day
The PV Series flowmeter is available with full-scale ranges from 50 CCM to 50 LPM 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 analogue signal.
The major advantage of this technology is no moving parts, which means a long, dependable life for the meter.
