Plug-in electromagnetic flowmeter sensor installed downstream straight pipe not less than 10 D motioned diameter (D), cheap straight pipe not less than 5 D
Plug-in electromagnetic flowmeter installation is as follows:
1, winding installation, the sensor into the pipe should be and winding diameter of the pipe section Angle is less than 5 degrees, in practical measurement of pipeline vibration small clean medium,
2, tilt installation, the sensor axis and the axis of the measured pipe Angle of 45 degrees, suitable for big diameter and measurement medium contain other impurities in the liquid flow measurement, small resistance of the installation of water, should not be bound to hang,
Sensor draw point there are two ways: one is the thorn into pipeline to be tested on the central axis (i.e., 1 present 2 times the pipe diameter); The second is thrust into the pipe inner surface of pipe 1 present 4,
The installation of sensors
1, measured pipe installation pedestal welding slag and clean up the burr,
2, turn off the downstream flow control valves or take high pressure water supply,
3, on the (ball valve installation to install base, pay attention to the the sky cavity up ball valve, can review the ball valve can fully open and close, threaded seat of compression, compression nut and rubber seal on the ball valve installation, loosen nut positioning and the sensor into rod through the ball into the pipeline under test, with the sensor should be paid attention to the direction mark pole pointing should work in harmony with the direction of flow,
