LDG-150S electromagnetic flowmeter installation in the key points

LDG-150S electromagnetic flowmeter not only meets the needs of on-site display, but also can output 4~20mA current signals for recording, adjustment and control. It is now widely used in chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage and other industrial technology and management departments. Selection of installation location of LDG-150S electromagnetic flowmeter: In order to make the electromagnetic flowmeter work stably and reliably, the following requirements should be paid attention to when selecting the installation location: 1. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields (such as large motor, large transformer, etc.) to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor. 2. It should be installed in a dry and ventilated place as much as possible. It should not be installed in a humid place or a place prone to water accumulation. Electromagnetic flowmeter installation requirements: In order to measure correctly, the following requirements should be noted when selecting the installation location on the pipeline: 1. The sensor can be installed on vertical pipelines, or on horizontal or inclined pipelines, but requires two electrodes The center line is horizontal. 2. The medium should flow fully into the tube at the installation position to avoid the tube being full and gas adsorbed on the electrode. 3. When the medium at the installation location of the flow meter is not full of the pipe, you can raise the pipe at the rear end of the flow meter to fill the pipe. It is strictly prohibited to install the flow meter at the highest point of the pipe and at the water outlet. 4. The length of the straight pipe section before and after the flow meter: the front section ≥ 10DN, the rear end ≥ 5DN (DN is the pipe diameter)

Wiring of LDG-150S electromagnetic flowmeter 1. The shorter the signal cable for split installation, the shorter the length. The better; 2. Signal cables must be strictly separated from other power lines; 3. Excess cables cannot be rolled together and should be cut off. When the cable enters the electrical interface of the sensor, make a U-shape at the port to prevent rainwater from penetrating into the sensor.
