Electromagnetic Flowmeter DN25MM Electrode Form Standard Interpolation 4-20 mA Current Output
Performance & Characteristics
l It is suitable for all liquid flow test of conductivity of greater than 5. Conductivity change does not affect the performance of the change.
l The flow meter has the long-term high accuracy of measurement. It actually is not affected by fluid physical properties. Measurement accuracy can be up to 1, 0.5.
l The flow meter is with no mechanical and moving parts, usually without maintenance.
l Convenient operation, the flow meter is set automatically according to the scope of 0 ~ 10 m/s, without change of measuring range.
l Because of all the parts in contact with the medium under test, have good corrosion resistance and wear resistance, so the applicability is wide.
l In measuring medium containing oil or to the electrode surface sedimentary cover a layer of conductive material medium, can choose a convertible (scrub) electrode.
l Use advanced excitation algorithm.
l Using the world's most excellent integrated circuit to eliminate the influence of excitation switch and using compensation method of excitation current, finally up to the optimal stability of the product.
l Use high efficiency, high stability and designed the wide input range of multiple sets of the isolating switch power supply.
(DC: 18-36V; AC: 85V-265V).
Have a lot of output interface design, using conveniently:
A) 4-20 mA current output;
B) To set the pulse output;
C) The RS485 interface. Self-check function.
l High-definition main LCD backlight display in Chinese of four lines on a large screen.
l When power off, EEPROM can protect set parameters and total value.
l Provide nonlinear correction function of five sections of sensor
l With functions of automatic operation for average flow rate, easy to calibration of instrument.
