KROHNE electromagnetic flowmeter VA45 for low pressure gas applications

VA45

Variable area flowmeter for low pressure gas applications

Glass tube with easy-to-read scale

For use in gas supply lines of furnaces, protective gas or heating systems

Flange: DN15…40 / ½…1½"; also NPT, G, hose connection

-20…+100°C / -4…+212°F; max. 1 barg / 14.5 psig

The VA45 is a glass tube variable area (VA) flow meter for flow measurement of gases at low operating pressures (<1 barg /<14.5 psig). The device is ideally suited for use in gas supply lines of industrial ovens, forges and furnaces or protective gas and heating systems (with process temperatures up to +100°C / +212°F).

Simple, low-cost measuring principle without auxiliary power

For direct reading of the flow and observation of the medium

Full scale value for gases: 2300…75,000 l/h / 85…2790 SCFH

Maximum measuring error: ±2.5% (acc. to VDI/VDE 3513-2) or ±2% of full scale

Turndown ratio: 10:1
