INSTALL ATTENTION FOR ELECTROMAGNETIC FLOWMETER
1. Horizontal and vertical installation
The sensor can be installed horizontally and vertically, but it should be ensured to avoid the influence of sediments and bubbles on the measuring electrode, and the electrode axis
should be kept horizontal. When installed vertically, fluid should flow from bottom to top.
2. The sensor cannot be installed at the highest position of the pipeline, as bubbles are likely to accumulate in this position.
3. Ensure full pipe installation
4. Installation between elbows, valves and pumps
In order to ensure the stability of the measurement, a straight pipe section should be set up before and after the sensor, the length of which is given in the figure below. If this is not possible,
a flow stabilizer should be used or the cross-sectional area of the measuring point should be reduced.
5. To avoid negative pressure, the sensor cannot be installed at the water inlet of the pump, but should be installed at the water outlet of the pump.
7. The inlet straight pipe section and the outlet straight pipe section of the sensor
The inlet straight pipe section should be ≥5D, and the outlet straight pipe section should be ≥3D (D is the nominal diameter of the sensor).
8. Series installation and parallel installation
If several sensors need to be connected in series on the same pipeline, the distance between each sensor should be at least 2 sensor lengths.
If two or more sensors are installed parallel to each other, the distance between the sensors must be greater than 1m.
