1) The installation height of the buoyancy level gauge should meet the specifications of the design document.
2) The buoyancy level gauge shall be installed with the buoys in a vertical position at the level of the normal operation level or the boundary level of the buoy.
3) The duct of the steel belt level gauge should be installed vertically, and the steel belt should be in the center of the duct and slide freely.
4) When using a differential pressure gauge or differential pressure transmitter to measure the liquid level, the height of the instrument should not be higher than the lower pressure extraction port. (This method is not affected by the air blowing method and the low-boiling liquid vaporization pressure transmission method for measuring the liquid level. Regulations limit).
5) Double-flange differential pressure transmitter capillary should be laid with protective measures, the bending radius of not less than 50mm, when the surrounding temperature change is severe, heat insulation measures should be taken.
6) The load sensor of the weighing level meter shall be installed and carried after the installation of the load-bearing container and all its components and connections.
7) -Generally measure the level of sewage, install the transmitter not to be installed at the bottom. The input type and pressure-conducting level gauge is put in from the top, leaving a certain distance from the bottom of the pool, more than 300mm is good, differential pressure / pressure / level transmitter installed in the side of the container, but also have a certain distance from the ground distance. 300mm can be.
8) Keep away from the pump, sewage pump and circulation pump when installing the level gauge. Avoid making the pool spray so that the measurement accuracy is not accurate.
9) In the industrial field, the moon float switch is usually used to control the start and stop of water and water. Although the float switch is cheap, the service life is very limited, and it is usually updated in one year or even several months. According to the author's on-site construction experience, the use of liquid level transmitters is relatively expensive, and it is generally desirable to use pressure transmitters, differential pressure transmitters, or pressure-conducting differential pressure transmitters and input level gauges. fair price.
