Selection of installation site
The measuring tube must be fully filled with medium at all times – electromagnetic flowmeters cannot operate normally when the tube is not full or empty.
1) Select a straight pipe section filled with liquid, such as a vertical section of the pipeline (the flow direction is preferably from bottom to top) or a horizontal pipe filled with liquid (the lowest point of the entire pipeline is the Xuan). During the installation and measurement process, non-full pipe conditions must not occur.
2) The measurement position should be selected at a location greater than 5D upstream of the flowmeter and a straight pipe section of 3D downstream.
3) The measurement points should be selected as far away as possible from pumps, valves and other equipment to avoid their interference with the measurement. 4) The measurement points should be selected as far away as possible from large radio frequency, strong magnetic fields, strong vibration interference sources, etc.
