Accuracy 0.5% thread connection turbine meter

Turbine Flow Meter engages a vaned rotor causing it to rotate at an angular velocity proportional to flow rate. the Turbine Flow Meter senses the spinning motion of the rotor inside the pipe & converts it into a pulsating electrical signal.

Summation of the pulsating electrical signal is directly related to the total flow. the frequency is linearly proportional to flow rate which is converted to electrical signed 4-20mA.

1. High accuracy and long life
2. Easy maintenance and installation
3. Widely used for factory, oil field, chemical, metallurgy, etc

Applications the sensor is suitable for measuring the liquid without any impurity such as fiber and particle and which does not corrode stainless steel SS304, 2Cr13, adamantine spar Al2O3 and rigid alloy.

the instrument parameter given by the inspection certificate is suitable for the situation which the media viscosity is smaller than 5X10-6m2/s in the working temperature.

in respect the liquid with the viscosity larger than 5X10-6m2/s, calibrate the sensor according to the actual liquid, and then use as per the new instrument parameter.

If users need to use the sensor of special type, it can order under the negotiation with us. If it needs explosion-proof sensor, specify in the order.

FIXING of INSTRUMENT
A) Fixing differs on various sizes of pipes

B) the instrument can be fixed horizontally, vertically or leaning, the pipe must be full of liquid and without gas in it

C) Follow the direction indicator on the surface of sensor, upstream length must be more than 20DN, downstream length at least 7DN

D) Instrument should be away from any electromagnetic field, shielding measures take should be taken if necessary.

E) If the flowmeter works in open air, a waterproof shell is recommended
