8、 Installation techniques for pulse turbine flowmeter

1. When installing a turbine flowmeter, attention should be paid to staying away from external electric and magnetic fields, and effective shielding measures should be taken if necessary to avoid external interference. Turbine flow meters can be installed horizontally or vertically, and the fluid direction must be upward when installed vertically. The liquid should fill the pipeline without any bubbles. During installation, the direction of liquid flow should be consistent with the direction indicated by the arrow on the sensor housing. During installation, the pipeline must be filled with fluid to ensure accurate measurement.

2. The upstream end of the flowmeter should have a straight pipe section at least 10 times the nominal diameter length, and the downstream end should have a straight pipe section at least 5 times the nominal diameter. The inner wall should be smooth and clean, without defects such as dents, scale, and peeling.

9、 Price of pulse turbine flowmeter products

The price of pulse turbine flowmeter is related to the medium, pressure, installation method, and diameter. The final price should be based on the on-site working conditions. Platinum Rui will provide you with the most favorable price and quality service!
