Double Spiral Rotor Flow Meter

Double Spiral Rotor Flow Meter

Double Spiral Rotor Flow Meter is an advanced positive displacement flow meter with features of high measurement accuracy, smooth running, no pulsation, low noise, long service life, strong adaptability to various viscosities and without requirement to the upstream and downstream straight pipe length. It is widely used in many industries such as petroleum, chemical, metallurgy, thermal power, shipbuilding, and food etc. It is especially suitable for trading measurement for crude oil, highly condensed oil, crude oil with water, petroleum products, as well as engineering measurement. The flow meter can be equipped with photo-electric pulse converter or electronic flow transmitter to output pulse signal or analog current signal for remote monitoring in the control room.
