Electromagnetic flowmeters have a wide range of applications, large-diameter instruments are mostly used in water supply and drainage projects; medium and small calibers are often used in high-demand or difficult-to-measure occasions, such as blast furnace tuyere cooling water control in the iron and steel industry, measurement of pulp and black liquor in the paper industry, and chemical industry. Strong corrosive liquid, ore pulp in non-ferrous metallurgy industry; small-diameter and micro-diameter are often used in places with hygiene requirements such as pharmaceutical industry, food industry, and biochemistry.
Features
The measurement channel is a smooth straight pipe, which will not be blocked. It is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, mud, sewage, etc.;
There is no pressure loss caused by flow detection, and the energy saving effect is good;
The measured volume flow is actually not significantly affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
Large flow range and wide caliber range;
Corrosive fluids can be applied.
Advantages
The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity; .
There are no obstructing flow parts in the measuring tube, no pressure loss, and the requirements for straight pipe sections are low;
The nominal diameter of the series is DN4 ~ DN3000. There are various options for sensor lining and electrode materials;
The converter adopts a novel excitation method, with low power consumption, stable zero point and high accuracy. The flow range can reach 1500:1;
The converter can be combined with the sensor to form an integral type or a separate type;
The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming;
The flowmeter is a two-way measurement system with three built-in totalizers: forward total, reverse total and difference total; it can display forward and reverse flow, and has a variety of outputs: current, pulse, digital communication , HART, RS485 protocol;
The converter adopts surface mount technology (SMT), with self-check and self-diagnosis functions;
Rubber and urethane lined sensor for intrinsic immersion structure;
Explosion-proof instruments can be used in corresponding explosion-proof places;
Electromagnetic flowmeter is used to measure the volume flow of conductive liquid and slurry in closed pipelines. It is suitable for chemical, electric power, metallurgy, petroleum, water supply and drainage, papermaking, medicine, food and other departments.
