Electromagnetic flow calculation instrument, water flow capacity calculation instrument, liquid pipeline flow calculation instrument, electromagnetic working flow sensorproduct description
Electromagnetic flowmeter (EMF) is the rapid development of electronic technology in the 1950s and 1960s.
A new type of flow measuring instrument developed rapidly. The electromagnetic flowmeter is based on the principle of electromagnetic induction, which is based on the electric current induced by the conductive fluid passing through the external magnetic field.
A gauge that measures the flow of a conductive fluid.
1.2 Electromagnetic flowmeter has the following characteristics
★Unaffected by changes in fluid density, viscosity, temperature, pressure and conductivity, the linear measurement principle enables high-precision measurements;
★There is no obstruction and moving parts in the measuring tube, the pressure loss is small, so it will not cause additional energy loss, and will not cause blockage.
It is especially suitable for the measurement of liquid-solid two-phase flow media such as sewage, mud, slurry, pulp, etc.
★The installation requirements are low. The front straight pipe section only requires 5D, and the rear straight pipe section is 2D (D is the inner diameter of the selected instrument)
★ Nominal diameter DN3-DN3000 Covering a wide range, lining and electrodes have a variety of options to meet the requirements of measuring a variety of conductive flow;
★ With MODBUS-RS485, HART, GPRS and PROFIBUS and other communication signal output (optional)
★The converter adopts 32-bit embedded microprocessor, full digital processing, fast calculation speed, strong anti-interference ability, reliable measurement, high precision, measurement
Range up to 1500:1
★High-definition backlight LCD display, full Chinese menu operation, easy to use, easy to operate, easy to learn and understand;
★ With conductivity measurement function, it can judge whether the sensor is empty or not, and has self-test and self-diagnosis function;
★ The internal calculator can display positive cumulative flow, reverse cumulative flow and instantaneous flow respectively.
★Plug-in electromagnetic flowmeter, easy to install, can continuously flow the field with pressure opening, has absolute installation advantages and price advantages.
1.3 Main applications
An electromagnetic flow meter can be used to measure the volumetric flow of a conductive fluid in a closed conduit. Widely used in petroleum, chemical, steel metallurgy, water supply and drainage,
Flow measurement and control in industrial and agricultural production processes such as water irrigation, water treatment, environmental sewage control, paper making, medicine, food, etc.
★Use environmental conditions
Ambient temperature: sensor -25°C~+60°C Converter -10°C~+60°C
Relative humidity: 5% to 95%
★ working conditions
Fluid conductivity: greater than 5μS/cm (electrical conductivity of tap water and raw water is about 100~5005μS/cm)
