1, intelligent metal pipe float flowmeter installation selection flange connection, flange connection and clamp-on type.
2, installation of liquid flow direction should be consistent with the direction of the arrow marked on the sensor housing inflow, and upstream straight pipe section should be ≥ 20dn, downstream straight pipe section should be ≥ 5dn (dn for the inner diameter of the pipe).
3, the sensor should be away from the external magnetic field, if it can not be avoided, the necessary measures should be used.
4, in order to maintenance will not affect the normal transmission of liquid, should be installed outside the straight pipe section on both sides of the panel type flowmeter sensor bypass pipeline (such as Figure IV).
5, the sensor outdoor installation, please make the amplifier plug waterproof treatment;.
6, the sensor and digital display instrument wiring, should be based on the power amplifier to select the wiring method, see the relevant "manual".
7, the liquid metal tube float flowmeter sensor can be level, vertical installation, vertical when the liquid direction must be up. Liquid should be filled with pipeline, not bubbles. When installed, the liquid flow direction should be consistent with the direction of the arrow marked on the sensor housing inflow. The upstream end of the sensor should be at least 20 times the length of the nominal diameter of the straight pipe section, the downstream end should be no less than 5 times the nominal diameter of the straight pipe section, the inner wall should be smooth and clean, no pits, scaling and peeling and other defects.
8, if the liquid is unstable with pulse flow, to ensure excellent measurement of the flowmeter can be installed buffer to clear the pulse flow. Flowmeter in use, should first slowly unscrew the control valve in the upstream pipeline of the flowmeter, and then use the adjustment valve to adjust the flow rate, to prevent the sudden opening of the float to rise sharply to damage the cone tube.
