　　3. Installation

　　1. Horizontal and vertical installation

　　Sensors can be installed horizontally and vertically, but it should be ensured to avoid the influence of sediment and bubbles on the measuring electrode, and the electrode axis should be kept horizontal. When installed vertically, the fluid should flow from bottom to top. Sensors cannot be installed at high positions in pipelines, as this location is prone to the accumulation of air bubbles.

　　2. Ensure full pipe installation

　　Ensure that the flow sensor is filled with the measured fluid in the pipeline during measurement and that there is no non full pipe state. If the pipeline is not full or the outlet is empty, the sensor should be installed on a siphon tube.

　　3. Installation between bends, valves, and pumps

　　To ensure the stability of the measurement, a straight pipe section should be installed before and after the sensor, with its length given. If it cannot be achieved, a current stabilizer should be used or the cross-sectional area of the measurement point should be reduced.

　　4. Sensors cannot be installed at the inlet of the pump

　　To avoid negative pressure, the sensor should not be installed at the inlet of the pump, but at the outlet of the pump.
