Precautions during the installation of the flowmeter
1) Before installing the Sensor on the process line, it is necessary to confirm whether the speed sensor coil, the DC resistance of the drive coil, and the resistance value of the platinum resistance thermometer are normal.
2) The sensor mounting flange must be coaxially connected with the pipe flange so as to reduce the installation stress and ensure the measurement accuracy. When installing, it should be ensured that the pipe supports only support the process pipe and the sensor is not allowed to support the process pipe. The sensor housing should be kept free from contact with any objects.
3) When the sensor is installed in the process pipeline, ensure that the piping system and the sensors at the upstream and downstream sides of the sensor are securely connected at two locations. All threaded connections must be secured. Clamping the process piping can help reduce potential vibration disturbances. .
4) During the installation of the flowmeter, the use of the sensor housing to move the sensor should be avoided.
5) Flowmeters The valves or pumps on the process line near the sensor installation position need their own support. The support for the sensors cannot be used to support the valves and pumps.
6) The flow meter should be equipped with a shut-off valve upstream and downstream of the sensor.
7) Eliminate installation stress: When installing the sensor, in order to eliminate the installation stress, the most effective method is to first pipe, pre-install the process pipeline and the valve and the sensor as a whole, then lifting, and then welding it with the process master line. In order to make the best effect of stress relief, the sensor, stop valve and process master line should be in the same vertical plane.
