Turbine Water Flow Meter
Turbine water flow meter first converts the flow rate into the rotation speed of the turbine, and then converts the rotation speed into an electrical signal proportional to the flow rate.The high accuracy and stable performance is the advangtage of turbine water flow meter .
What’s the working principle of the turbine liquid flow meter?
Turbine Water Flow Meter is a speed-type flow measurement instrument with temperature and pressure compensation functions. Its working principle is: the power of the flowing fluid drives the turbine blades to rotate, and the rotation speed is approximately proportional to the volume flow. The fluid volume is indicated by the flow meter. Values are based on turbine wheel revolutions.
In what fields can turbine water flow meters be used?
Turbine Water Flow Meter are widely used in petroleum, chemical industry, electric power, gas pipeline networks, etc. due to their high measurement accuracy, good repeatability and stability, wide measuring range, rapid response to flow changes, strong anti-interference ability, and easy signal transmission,city gas and other fields.
