Installation example diagram and requirements of electromagnetic flowmeter manufacturer Xi'an intelligent flowmeter
1. Electromagnetic flow meters should be installed at the lower and vertically upward positions of horizontal pipelines, avoiding installation at the highest points and vertically downward positions of pipelines;
2. The electromagnetic flowmeter should be installed at the rising point of the pipeline;
3. When installing an open discharge pipeline, it should be installed at the lower part of the pipeline;
4. If the pipeline drop exceeds 5m, install an exhaust valve downstream of the sensor;
5. Electromagnetic flow meters should be installed with control valves and shut-off valves downstream of the sensor, rather than upstream of the sensor;
6. The sensor * * * cannot be installed at the inlet and outlet of the pump, it should be installed at the outlet of the pump;
7. The method of installing electromagnetic flowmeter in the measuring well;
Remarks: 1. Inlet 2. Overflow pipe 3 Inlet grille 4. Cleaning hole 5. Flow meter 6. Short pipe 7. Outlet 8. Discharge valve
How to correctly select installation nodes for electromagnetic flow meters:
Choosing the correct installation point and installing the flow meter correctly are both very important steps. If there is a mistake in the installation process, it can affect the measurement accuracy in mild cases, the service life of the flow meter in severe cases, and even damage the flow meter.
Special attention should be paid when selecting the installation location:
The axis of the non measuring electrode must be approximately horizontal;
The measuring pipeline must be completely filled with liquid;
There should be at least a 5 * D (D is the inner diameter of the flowmeter) straight pipe section in front of the electromagnetic flowmeter, and at least a 3 * D (D is the inner diameter of the flowmeter) straight pipe section behind it;
The flow direction of the fluid is consistent with the arrow direction of the flowmeter;
Vacuum inside the pipeline can damage the lining of the flowmeter, so special attention should be paid;
There should be no strong electromagnetic field near the electromagnetic flowmeter;
There should be ample space near the electromagnetic flowmeter for installation and maintenance;
If there is vibration in the measuring pipeline, there should be fixed supports on both sides of the flowmeter. When measuring mixed liquids of different media, the distance between the mixing point and the flowmeter should be at least 30 × D (D is the inner diameter of the electromagnetic flowmeter). To facilitate the cleaning and maintenance of the flowmeter in the future, a bypass pipeline should be installed;
