Thanks so much for your support!

Performance & Characteristics

● It is suitable for all liquid flow test of conductivity of greater than 5. Conductivity change does not affect the performance of the change.

●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(Optional).

●The flow meter is with no mechanical and moving parts, usually without maintenance.

●Convenient operation, the flow meter is set automatically according to the scope of 0 ~ 10 m/s, without change of measuring range.

●Because of all the parts in contact with the medium under test, have good corrosion resistance and wear resistance, so the applicability is wide.

●In measuring medium containing oil or to the electrode surface sedimentary cover a layer of conductive material medium, can choose a convertible (scrub) electrode.

●Use advanced excitation algorithm.

●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.

●Use high efficiency, high stability and designed the wide input range of multiple sets of the isolating switch power supply:

85V-250VAC or 21V-36VDC(Optional)

Have a lot of output interface design, using conveniently:

A) 4-20 mA current output;

B) The RS485 interface. Self-check function.

●High-definition main LCD backlight display in Chinese of four lines on a large screen.

●When power off, EEPROM can protect set parameters and total value.

●Provide nonlinear correction function of five sections of sensor

●With functions of automatic operation for average flow rate, easy to calibration of instrument.

Installation

Note for installation

1. Environment for installation should be dry and wind, avoid shining from sun, temperature of environment is not more than 40℃.

2. It should be far away from high magnetic place o electric equipment. Such as large transformer, welding machines.

3. It is should be far away from the place including NH3, acid fog.

4. The direction of fluid flow is similar with flow mark.

5. Pipe is installation should be filled with measuring medium. it cannot be empty.

6. The instrument should not be installed inside pipe with negative pressure avoiding lining shedding.
