Vortex Flow meter
Vortex Flowmeter is used to measure the flow of liquids, Gases or Steam in pipelines. Its characteristics are no pressure loss, no moving parts and no maintenance. Though it is similar to Electro Magnetic Flowmeter the one advantage Vortex Meter has over EMF is the medium need not be conductive as in the case of EMF. This flowmeter adopts piezoelectric sensor, has high reliability, and works with in –200C to +2500C. It gives standard analogue signal (4 ~ 20mA) or Digital pulse signal outputs. It is compatible with digital systems like Computer, DCS Systems, Dataloggers, etc.
Features:
-Medium: Superheated Steam, Saturated Steam, Compressed Air, water, other gases and liquids.
-Accuracy: +/-1.0% (liquid), +/-1.5% (gas)
-Rated Pressure (optional): 1.6MPa, 2.5MPa, 4.0MPa
-Temperature of Medium: -40°C~+350°C
-Operated Power: 24V DC, Built in battery (can work lasting for 2 years)
-Output Signal (optional): 4-20mA, RS-485, HART
-Protection Grade: IP65
-Ambient Temperature: -40°C~+60°C (without LCD), 0°C~+60°C (with LCD)
-Ex-proof: Exd II BT3-6
- oil flow switch, gear flow meter, oval gear flow meter
