Installation precautions for acid-base liquid flow meters
1. The sulfuric acid flowmeter should be installed at the lower and vertically upward positions of the horizontal pipeline, avoiding installation at the highest and vertically downward points of the pipeline.
2. It should be installed at the rising point of the pipeline. When installing in the 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. The sensor * * * cannot be installed at the inlet and outlet of the pump, but should be installed at the outlet of the pump.
6. There should be at least a 10 * D (D is the inner diameter of the flowmeter) straight pipe section in front of the flowmeter, and a 5 * D straight pipe section behind it.
