SH-LWGY turbine flowmeter
1.Turbine flowmeter description
Turbine flowmeter is a speed meter with high precision, high pressure resistance, wide measuring range, small pressure loss, long life, simple operation and convenient maintenance. It is used for measuring low viscosity and no corrosiveness in closed pipelines. , volume flow and cumulative flow of cleaning liquid. Can be widely used in petroleum, chemical, metallurgical, pharmaceutical, food, paper and other industries.
2.Suitable medium
Low viscosity liquid: water, wine, milk, gasoline, diesel, cooking oil, etc.
2.Working principle
The sensing coil mounted outside the casing detects the rotational speed of the turbine. When the turbine blade cuts the magnetic flux generated by the permanent magnet in the casing, it causes a change in the magnetic flux in the sensing coil, and the sensing coil will detect the magnetic flux. The cycle change signal is sent to the amplifier, and the signal is amplified and shaped to generate a pulse signal proportional to the flow rate, which is sent to the unit conversion and flow integration circuit to obtain and display the cumulative flow value.
