Turbine Flow meter
1. Product Features
Medium temperature: -20~+120º C
Ambient temperature: -20~+55º C
High quality turbine resulting in wider measurement range than conventional ones
Various types of transducers for different applications
The unique Multi-point intelligent non-linear correction to the instrument coefficient
Accuracy assurance due to the standard flow calibration facilities
100% pressure experiment, 100% products quality inspection
Power-Off Protection: The instrument coefficient and the accumulative flow value can be saved for ten years without power
2. Basic Parameters
Sensors of which diameter ranges from DN4 to DN40 are screw thread connection and the maximum pressure tolerance is 6.3Mpa
Sensors of which diameter ranges from DN50 to DN200 are flanged connection and the maximum pressure tolerance is 6.3Mpa
Sensors of which diameter ranges from DN4 to DN40 have straight pipes and filters upstream and downstream.
Our company supplies upstream and downstream straight pipes for the sensors with their diameters lager than DN15
