Product Introduction
Intelligent Electromagnetic Flow Meter is composed of sensor and converter. It is based on Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquid with conductivity greater than 5s/cm. It is an inductive instrument for measuring volume flow of conductive medium, besides measure the volume flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strong liquid and strong corrosive liquids such as strong acid and strong alkali, and even liquid solid two phase suspension liquid such as slurry, pulp and pulp. It is widely used in oil, chemical, metallurgy, textile, papermaking, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other areas of flow measurement.
Features
The measurements are not affected by the changes in the density, viscosity, temperature, pressure and electrical conductivity of the fluid.
There is no pressure loss in the measurement tube, and the requirement of the straight pipe section is low. It has a unique adaptability to the measurement of slurry.
The rational selection of electrode and lining material, that is, has good corrosion resistance and wear resistance.
Full digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range ratio of up to 150:1
The ultra low EMI switching power supply is suitable for large change range of power supply voltage and good performance against EMI.
Using 16 bit embedded microprocessor, the operation speed is fast, the precision is high, the programmable frequency is low frequency rectangular wave excitation, and the stability of the measurement is improved and the power consumption is low.
The reliability of the circuit is high by using SMD device and surface mounting (SMT) technology.
There is no movable part in the pipe, no flow component, and there is little additional pressure loss in the measurement.
In the field, the range can be modified online according to the actual needs of the user.
The measurement results have nothing to do with the distribution of flow velocity, fluid pressure, temperature, density, viscosity and other physical parameters.
High definition backlight LCD display, all Chinese menu operation, easy to use, easy to operate, easy to learn and easy to understand.
With R5485, RS232, HART and Modbus Profibus-DP and other digital communication signal output (selection).
It has the function of self examination and self diagnosis.
Hourly total recording function, recording the total amount of flow in an hour, suitable for time sharing measurement system (selection)
The internal rearing three integrators can display the reverse cumulant and the difference value of the positive cumulant respectively. There is a power drop clock in the inside, and the 16 times of power fall can be recorded. (Selection)
Infrared hand-held operator, 115KHZ communication rate, all functions of remote non-contact operation converter (optional)
