LDG-450 electromagnetic flowmeter

Description :

　　This product has measurement value power-off protection and air traffic control alarm function. The flow direction of the fluid can be set, so the installation of the sensor is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.

　　1、 Characteristics

　　Small size, light weight, easy installation, and low maintenance;

　　Wide measurement range, unaffected by changes in fluid temperature, density, pressure, viscosity, conductivity, etc;

　　It can be installed by drilling holes on old pipelines, with simple construction and installation, and a small amount of work;

　　Compared to general electromagnetic flow meters, it has lower costs and installation expenses, making it particularly suitable for measuring flow in large and medium-sized pipelines;

　　Adopting advanced processing technology, solid-state packaging, long service life, and ensuring good measurement accuracy and stability of the instrument;

　　Simple structure, sturdy and reliable, long service life (and suitable for measuring seawater);

　　There are no moving parts or resistance parts inside the measuring tube, no pressure loss, and no blockage will occur;

　　Reliable measurement and strong anti-interference ability.

　　2、 Technical parameters

　　PTFE lining: -30 to+100 ℃; High temperature PTFE lining: -20 to+180 ℃

　　Rated working pressure: (high pressure can be customized) DN10- DN150: ≤ 1.6MPa; DN200－DN350：≤1.0MPa

　　DN400－DN1000：≤0.6MPa； DN450－DN2200：≤0.25MPa

　　Flow velocity range: 0.1-15m/s

　　3、 The installation steps are as follows

　　It can be installed on vertical pipelines or on horizontal or inclined pipelines, but it is required that the center line of the two electrodes be in a horizontal state.

　　The medium should flow fully in the installation position to avoid incomplete pipes and gas adsorption on the electrodes.

　　When the installation position of the flowmeter is not filled with the medium, the method of raising the rear pipeline of the flowmeter can be adopted to fill the pipeline. It is strictly prohibited to install the flowmeter at the high point and outlet of the pipeline.

　　The length of the straight pipe section before and after the flowmeter: the front section is ≥ 10DN, and the rear section is ≥ 5DN (DN is the pipe diameter)

　　For flange connection, spot weld the matching flange onto the pipeline and connect the bolt to the flange on the body. Perform welding again.

　　The installation method involves welding the two flanges and pipelines on the main body, installing the flow meter together with bolts and nuts, and then spot welding.

　　Wiring of electromagnetic flowmeter:

　　The shorter the signal cable for the split installation connection, the better;

　　Signal cables must be strictly distinguished from other power lines.
