Turbine flow meter consists of turbine flow sensor and display instrument and it is made by us using foreign state-of-the-art technologies, which is an ideal gauge for measuring of liquid flow.
Applications:
1.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.
2.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.
3.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.
4.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.
Configuration selection:
LWGY-N Type Sensor: 12 to 24V DC Power Supply; Pulse Output
LWGY-A Type Transmitter: 24V DC Power Supply; 2-wire 4 to 20 mA Output
Basic Type (Without Explosion Proof) and Explosion Proof Type are optional for LWGY-N and LWGY-A.
LWGY-B Type: powered with 3.2V10AH lithium battery (Battery life > 3 years); no output
LWGY-C Type: 24V DC Power Supply; 2-wire 4 to 20 mA Output (Optional: RS485 or HART)
