Working principle:
The turbine flowmeter is a leading variety of the vane-wheel flowmeter. When the measured fluid passes through the turbine flowmeter, under the fluid effect, the multi-blade wheel will rotate, and the vane wheel speed is in direct proportion to the pipeline fluid flow speed. By the magnetic induction method, the vane wheel rotation movement can be detected, and the fluid flow can be deduced.
Main purpose:
The liquid turbine flowmeter can be used to measuring the clean liquid with low viscosity, such as the running water, petroleum,gasoline, light oil, light diesel, naphtha, ethylene, polyethylene,styrene, ammonia water, methanol, alcohol, ethanol, benzene,toluene, dimethylbenzene, butadiene, carbon tetrachloride,methylamine, acrylonitrile, etc.
Application field:
It can be widely applied in the petroleum, chemical engineering,electric power and machinery fields.
Main characteristics:
With high measurement precision and good repeatability; With small lower limit of the speed and wide range; With reliable performance and long service life due to application of the hard alloy bearing; With stronger shake-proofing and anti-electromagnetic interference capabilities; With small starting flow and small pressure loss.
