The liquid turbine flow meter is used to measure the flow rate of low viscosity liquid in closed pipe ranging from DN4 to DN200 mm. With the advantages of high accuracy, good repeatability, simple structure, small pressure loss and convenient maintenance, the turbine flowmeter is widely applied in the petroleum, chemical, metallurgy, water supply, paper and other industries.

Tips: Turbine Flow Meter Working Principle
When the fluid passes through the sensor of the turbine flow meter through the pipe, the impeller in the sensor rotates under the impulse of the fluid. The impeller changes the magneto-resistance in the magneto-electric induction system periodically, so that the magnetic flux through the coil changes periodically and produces the electric pulse signal. After the circuit amplification processing, the output has a certain amplitude of the continuous rectangular pulse, the field can directly display the measured flow, or the signal can be transmitted to the display instrument or communication output.
Precautions for turbine flowmeter installation and use
1. The turbine flow meter should be away from external electric and magnetic fields.
2. The upstream end of the flowmeter is recommended to keep at least 10D straight pipe segment (D is the nominal diameter of the pipeline), and the downstream end is not less than 5D straight pipe segment.
3. When there are impurities in the fluid, filter should be added.
4. At the beginning of the use of the turbine flowmeter, the flow sensor should be slowly filled with liquid, and then the outlet valve should be opened. It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in the state of no liquid.
