Tri-clamp Electromagnetic Flow Meter Installation & Maintainance
Installation
1. The sensor is installed vertically (fluid flows from bottom to top). In this position, when the liquid is not flowing, solid matter will precipitate, and oily matter will not settle on the electrode if it floats up.
If it is installed horizontally, the pipe must be filled with liquid to avoid air pockets from affecting the measurement accuracy.
2. The inner diameter of the pipe should be the same as the inner diameter of the flow meter to avoid throttling.
3. The installation environment should be far away from strong magnetic field equipment to prevent interference.
4. When using electric welding, the welding port must be far away from the sensor to prevent damage to the lining of the clamp-type electromagnetic flowmeter due to overheating of the sensor or flying in of welding slag.
lnstall at the lowest point and vertical upward direction
Don't install at the highest point or vertical downward diection |
When drop is more than 5m, install exhaust
valve at the downstream |
lnstall at the lowest point when used in open drain pipe |
Need 10D of upstream and 5D of downstream |
Dont' install it at the entrance of pump, install it at the exit of pump |
lnstall at the rising direction |
Maintenance
Routine maintenance: only need to make periodic visual inspections of the instrument, check the environment around the instrument, remove dust and dirt, ensure that no water and other substances enter, check whether the wiring is in good condition, and check whether there are newly installed strong electromagnetic field equipment or newly installed wires near the instrument Cross-instrument. If the measuring medium easily contaminates the electrode or deposits in the measuring tube wall, it should be cleaned and cleaned regularly.
