LDG-500 Pipeline Electromagnetic Flow Meter

Description :

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid.

　　1、 Technical parameters:

　　Communication output: RS485, MODBUS protocol, HART protocol

　　Power supply: AC220V or DC24V

　　Requirement for straight pipe length: upstream ≥ 5DN, downstream ≥ 2DN

　　2、 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.

　　3、 Selection of installation location:

　　1. The flow direction indicator on the sensor must match the direction of the measured medium flow inside the pipeline.

　　2. The installation position must ensure that the measuring tube is filled with the measured medium.

　　3. Choose a location with smaller fluid flow impulse, which should be away from the pump and local resistance components (valves, elbows, etc.)

　　4. When measuring two-phase fluids, a location that is not prone to phase separation should be selected.

　　5. Installation in areas with negative pressure inside the pipe should be avoided as much as possible.

　　6. When the measured medium easily causes adhesion and scaling on the inner wall of the electrode and measuring tube, it is recommended that the flow velocity inside the measuring tube should not be less than 2m/s.
