Turbine Flowmeter

LWG type turbine flow sensor and receiving electrical signals of the display instrument of turbine flowmeter, which is used to measure low and medium viscosity closed pipes
Degree of fluid (liquid or gas), the total volume flow and in petroleum, chemical industry, metallurgy, aviation and scientific research departments for a wide range of applications.
Sensor is composed of turbine sensor components and amplifier, the structure of the two together for one-piece: to measure the structure of the positive and negative flow
For two-way type; With inserted rod can be installed in the large diameter pipe flow body flow structure for a plug-in.
Based on the principle of moment balance sensor work. When the fluid flows through the sensor, promote the impeller rotation, when the flow rate must be dynamic torque
Maintain and drag torque balance, the impeller speed. Evenly distributed on the permeability of the impeller blade with the impeller rotation, to periodically change detection
The reluctance of the magnetic field sensor (coil), electrical pulse signal detector, after the amplifier amplification output. The output electric pulse frequency and impeller speed
Is proportional to the impeller speed is proportional to the flow in, so the output electric pulse frequency is proportional to the flow sensor flow, 4-20 ma signal is converted is proportional to the flow.
