ATWY Threaded Liquid Turbine Flowmeter

1.The sensor can be installed horizontally or vertically. When the sensor is installed vertically, the fluid direction must be upward. The liquid should fill the pipe without bubbles. When installing, the liquid flow direction should be consistent with the direction of the arrow indicating the flow direction on the sensor housing. The upstream end of the sensor should have at least 20 times the nominal diameter of the straight pipe section, the downstream end should be not less than 5 times the nominal diameter of the straight pipe section, the inner wall should be smooth and clean, no dents, scaling and peeling defects. The pipe axis of the sensor should be aligned with the adjacent pipe axis, and the gasket used for connecting the seal should not penetrate into the inner cavity of the pipe.

2.The sensor should be far away from the external electric and magnetic fields, and effective shielding measures should be taken if necessary to avoid external interference.

3.In order not to affect the normal delivery of liquid during maintenance, it is recommended to install a bypass pipeline at the installation place of the sensor.

4.When the sensor is installed in the open air, please make the amplifier and plug waterproof. The connection between the sensor and the display instrument is shown in Figure 4.

5.When the fluid contains impurities, the filter should be installed, and the filter mesh depends on the flow rate of impurities, generally 20 to 60 mesh. When free gas is mixed in the fluid, an air eliminator should be installed. The entire piping system should be well sealed.

6.The user should fully understand the corrosion of the measured medium and strictly prevent the sensor from being corroded.
