RS485 4-20mA analog MODBUS HART PCB electromagnetic flow meter transmitter
DFLD-YGD electromagnetic flowmeter is a kind of high precision and high reliability flowmeter. It is used to measure the volume flow of conductive liquid and slurry in a closed pipe, and widely used in iron and steel, electric power, petroleum, chemical, coal, metallurgy, mineral, paper, water supply, food, medicine and other industries.
- The accuracy will be unaffected by the change of fluid density, viscosity, temperature, pressure and conductivity.
- There are no parts which will impede flow in the measurement tube, no pressure loss, and the need of straight section is lower.
- The converter use display, it is easy to read the data in the straight sun and dark room.
- Setting parameters through infrared though button, so we can set parameters safely without opening the cover of converter under harsh environment.
- The flowmeter has bidirectional measuring system and is installed with three totalizers: forward total volume, reverse total volume and total difference; it can display forward flow and reverse flow volume, and has multiple outputs: current, pulse, digital communication, HART.
- The converter has self-inspection and self-diagnosis function;
- The sensor of high pressure electromagnetic flow meter use PFA and net lining material, have the advantages of high pressure resistance, anti-negative pressure. It specially used in petrochemical, mineral, etc.
- Explosion-proof type flow meter can used in corresponding explosion- proof area.
