    System Time 2021/03/08 System time adjustable 11:57:54 LCD Brightness LCD screen 1~5 adjustable brightness 7 Installation The electromagnetic flowmeter must work under the condition of full pipe, and the flowmeter cannot work normally when the pipe is not full or empty. During installation, the positive direction of liquid flow should be consistent with the direction of the flow arrow on the sensor, and there must be enough space for installation and maintenance near the flowmeter.
  • Page 16 Figure 2 Straight pipes before and after installation In order to ensure the upstream piping conditions required for high accuracy measurement of the flowmeter, the piping installation as shown in the figure below is recommended. According to the position where the electromagnetic flowmeter is installed, when there are valves at the front and rear, the smallest straight pipe section must meet the installation distance of the first 10D and the rear 5D, and the valve needs to be fully opened, as shown in Figure 3.

  • Page 17: Modbus Rtu Communication

    Figure 5 When the electromagnetic flow is installed at the rear end of the valve and the valve is not fully open, the plug-in electromagnetic flowmeter and the rear end of the valve must be at least the first 20D straight pipe section, as shown in Figure 6.
