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.
