When installing the electromagnetic flowmeter, the axis of the measuring electrode must be approximately horizontal, and the measuring pipe must be filled with liquid.
Precautions for installing electromagnetic flowmeter
1. The measurement of flow is not affected by changes in density, viscosity, temperature, pressure and conductivity of the fluid. The sensor-induced voltage signal has a linear relationship with the average flow rate, so the measurement accuracy is high.
2． There are no flow obstructions in the measuring pipe, so there is no additional pressure loss; there are no moving parts in the measuring pipe, so the sensor has an extremely long life.
3． Since the induced voltage signal is formed in the middle of the entire magnetic field and is an average value on the pipe surface, the straight pipe section required for the sensor is shorter, with a length of 5 times the pipe diameter.
4． A variety of electrode and lining materials can meet the requirements of corrosion resistance and wear resistance.
5． HY-LDE converter adopts the latest single-chip microcomputer and surface mount technology, with reliable performance, high precision, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese to display the LCD, which displays cumulative flow, instantaneous flow, flow rate, flow percentage, etc. .
6. The bidirectional measurement system can measure forward flow and reverse flow. Special production processes and materials are used to ensure that the product's performance remains stable over a long period of time.
When installing the electromagnetic flowmeter, the axis of the measuring electrode must be approximately horizontal, and the measuring pipe must be filled with liquid. There should be at least 5D (D is the inner diameter of the flowmeter) straight pipe section in front of the flowmeter, and there should be at least 3D straight pipe section in the back. The flow direction of the fluid is consistent with the arrow direction of the flowmeter. If there is a vacuum in the pipeline, it will damage the lining of the flow meter, so special attention is required. There should be no strong electromagnetic fields near the flowmeter and ample space for installation and maintenance. If the measuring pipe vibrates, there should be fixed supports on both sides of the flow meter. When measuring mixed liquids of different media, the distance between the mixing point and the flow meter must be at least 30D (D is the inner diameter of the flow meter). To facilitate future cleaning and maintenance of the flow meter, a bypass pipe should be installed. When installing a PTFE-lined flowmeter, the bolts connecting the two flanges should be tightened evenly, otherwise the PTFE lining will be easily crushed, so use a torque wrench.
1. It should be installed at the lower and vertical points of the horizontal pipeline, and avoid installation at the high points and vertical points of the pipeline.
2. It should be installed at the rising point of the pipeline.
3. When installing a pipeline with an open discharge, it should be installed at the lower part of the pipeline.
4. If the pipeline drop exceeds 5m, install an exhaust valve at a high position downstream of the sensor.
5. The control valve and shut-off valve should be installed downstream of the sensor and not upstream of the sensor.
6. The sensor cannot be installed on the suction side of the pump. It should be installed on the suction side of the pump. At the outlet
