Split LDG electromagnetic flowmeter LDG-300 explosion-proof electromagnetic flowmeter

Description :

　　This product has a simple and reliable structure, no movable parts, and a long working life. No flow blocking components, no pressure loss or fluid blockage. 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.

　　1、 Characteristics:

　　The sensor adopts an integral welded structure with good sealing performance;

　　The structure is simple and reliable, with no moving parts inside and almost no pressure loss;

　　The measurement accuracy is not affected by changes in physical parameters such as pressure, temperature, density, viscosity, etc. of the measured medium; Accuracy is not sensitive to changes in velocity distribution (except for vortices);

　　Equipped with conductivity measurement function, it can distinguish whether the sensor is empty or not; Adopting a 16 bit embedded microprocessor, it has fast computing speed and high accuracy; There are two integrators inside, which display forward and reverse accumulation and difference accumulation respectively; Capable of outputting RS485 or RS232C digital communication signals;

　　Containing digital processing, strong resistance to F-interference, reliable measurement, and high accuracy; The instrument is sensitive, the output signal is proportional to the flow rate, and the range ratio is wide;

　　Ultra low EMI switching power supply is suitable for a wide range of power supply voltage changes and has good EMC resistance performance; It includes Chinese and English menu operations, easy to use, simple to operate, easy to learn and understand.

　　3、 Selection of installation location:

　　1. The flow direction indicator on the sensor must be consistent with 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.
