How to install an electromagnetic flowmeter?

The installation of electromagnetic flow meters must strictly follow the specifications to ensure measurement accuracy and stable operation of the equipment. The specific installation points are as follows:

1. The installation position requires ensuring that the pipeline is filled with liquid. The measuring tube must always be completely filled with liquid, otherwise it will cause abnormal flow display or measurement errors.

. If there is a diversion or solid particle sediment in the fluid, it is recommended to install it vertically, and the fluid direction should be from bottom to top to avoid vibration, dust, and pipeline cavities. To prevent bubbles from entering the measuring tube and interfering with the measurement signal, it is necessary to design the pipeline to avoid the accumulation of bubbles. If there is a valve near the measuring tube, the flowmeter should be installed upstream of the valve to prevent pressure drop from causing bubble formation. Secondly, the installation direction should avoid the electrode being perpendicular to the ground. If the electrode is installed vertically, bubbles at the top or sediment at the bottom may cause measurement errors. The junction box of the split type flowmeter and the integrated converter need to be installed at the top of the pipeline system to ensure that the electrodes are level.

3. The straight pipe section requires reducing the interference of magnetic field and flow field. Equipment that may interfere with the magnetic field, induction signal or flow field distribution (such as pumps, valves, etc.) shall not be installed near the measuring pipe.

. Ensure the length of the upstream and d Flow meter installation specifications

ownstream straight pipe sections under normal operating conditions: a straight pipe section with a diameter of 5 times the diameter (5D) upstream and 3 times the diameter (3D) downstream is required. Including turbulence components (such as elbows and valves): The length of the straight pipe section needs to be extended, which needs to be adjusted according to the site conditions. Valve installation position: It is strongly recommended to install the valve downstream of the flow meter to avoid flow fluctuations in the measuring tube or empty tube counting. Maintain stable fluid conductivity and avoid installing flow meters at locations with uneven conductivity. If chemical substances need to be injected upstream, they should be moved downstream or a sufficiently long straight pipe section (about 5D) should be reserved to ensure uniform mixing. 4. Choose the installation location to avoid strong magnetic fields and electromagnetic interference, and stay away from strong electromagnetic equipment such as large motors and transformers to prevent signal interference. The environmental conditions require installation in a dry and ventilated area, avoiding damp and waterlogged environments. To prevent exposure to sunlight and rain, the ambient temperature should be ≤ 60 ℃ and the relative humidity should be ≤ 95%. Choose a location that is convenient for maintenance and construction. The pipeline layout requires that the flow meter must be installed at the rear end of the water pump and cannot be placed on the suction side. The valve should be installed on the downstream side of the flow meter.

Fifth, the installation position of the pipeline should be selected. Electrode horizontal installation sensors can be installed
