Jiangsu LDG-50 electromagnetic flowmeter

Description :

　　Jiangsu LDG-50 electromagnetic flowmeter

　　The main components of this product are: measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. It is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, salts, etc.

　　1、 Characteristics:

　　The structure is simple, reliable, without moving parts, and has a long working life.

　　No flow blocking components, no pressure loss or fluid blockage.

　　No mechanical inertia, fast response, good stability, can be applied to automatic detection, adjustment, and program control systems.

　　The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc.

　　Different combinations of PTFE or rubber lining materials and electrode materials such as HC, HB, 316L, Ti can adapt to the needs of different media.

　　There are various flow meter models available, including pipeline type and plug-in type.

　　Using EEPROM memory, the storage of measurement and operation data ensures safety and reliability.

　　It has two forms: integrated and separated.

　　High definition LCD backlit display.

　　3、 Installation:

　　1. It should be installed indoors in a dry and ventilated area. Avoid installation in areas with high ambient temperatures, avoid strong vibrations, and try to avoid equipment with strong magnetic fields. Such as large motors, transformers, etc. Avoid installation in environments with corrosive gases. The installation location should be convenient for maintenance, which is the environmental condition to ensure the normal operation of the transmitter.

　　2. Valves and bypasses should be installed at both ends of the electromagnetic flow transmitter.

　　3. In order to ensure that the measuring tube of the electromagnetic flow transmitter is filled with the measured medium, the inverter is installed vertically with a flow direction from bottom to top. Especially for liquid-solid two-phase flow, it must be installed vertically. If only horizontal installation is allowed on site, it must be ensured that the two electrodes are on the same horizontal plane.

　　4. To avoid interference signals, the signal between the transmitter and the converter must be transmitted using shielded wires. It is not allowed to parallel signal cables and power lines in the same cable steel pipe. The length of signal cables should generally not exceed 30m.
