Характеристики

Electromagnetic flowmeter is a new type of flowmeter developed rapidly with the development of electronic technology from 1950s to 1960s. Electromagnetic flowmeter is an instrument which uses electromagnetic induction principle to measure the flow of conductive fluid according to the electromotive force induced by conductive fluid passing through an external magnetic field.

Product Description :

YEZON Electroplating and corrosion prevention mud integrated pipe type electromagnetic flowmeter PL111, the sensor and the converter. It is based on Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquid whose conductivity is greater than 5 μs/cm. It is an inductive instrument to measure the volume flow of conductive medium. Besides measuring the general conductive medium, it can also measure strong acids, strong alkali, mud glue and other special liquids. It is widely used in petrochemical, papermaking, environmental protection, food and municipal water conservancy testing and other fields.

Product Features:

A. measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
B. There are no blocking parts in the measuring pipe, no pressure loss, low requirements for straight pipe section, and unique adaptability for slurry measurement.
C. reasonable choice of electrode and lining materials, that is, good corrosion resistance and wear resistance.
D. digital processing has strong interference ability, reliable measurement and high accuracy.
E. ultra low EMI switching power supply, suitable for a wide range of power supply voltage, good anti EMI performance.
F. uses 16 bit embedded microprocessor, and its operation speed is fast and precision is high.
G. adopts SMD and surface mount (SMT) technology, and the circuit has high reliability.
H. can be equipped with RS485, RS232, HART, MODBUS PROFIBUS-DP and other digital signal output.
I. high definition backlight LCD display, easy to use, simple operation, easy to learn and understand.
J. Hourly Total Recording Function, Recording the Total Flow in Hours, Used for Time-sharing Measurement Values (Customized Selection)
There are three accumulators in K., which can show the positive cumulant reverse accumulation and difference accumulation respectively. The internal power failure clock can record the 16 power down time. (custom selection)
L. infrared handheld operator, 115KHz communication frequency, remote non-contact operation converter all functions. (custom selection)
