Main Features

1.Suitable for flow (Heat) displaying, calculating and controlling of all kinds of liquids, single or mixed gases and vapor.

2. Input multiple flow sensor signals (Such as VSF, Turbine, Electromagnetic, Roots, Elliptical gear, Duplex rotor, Orifice plate, V-cone, Annubar, and Thermal flowmeter, etc.).

3. Flow input channel: Receive frequency and multiple current signals.

4. Pressure and temperature input channel: Receive multiple current signals.

5. Provide 24VDC and 12VDC power supply with short circuit protection, simplify the system and save investment.

6. Fault-tolerance: When the compensation measurement signals of temperature, pressure or density are abnormal, compensate with the manual setting of the corresponding operation.

7. Circular display: Provide convenience to monitor multiple process variables.

8. the update cycle of output current signal is 1 second, which can meet the requirements of the automatic control.

9. Configure with Instrument clock, automatic meter reading and print function, provide convenience for metering management.

10. Self-test and self diagnosis make the instrument more easy to use and maintain.

11. 3 -level password to prevent unauthorized personnel to modify parameters.

12. There are no potentiometer, code switch and other adjustable devices, that can improve the vibration resistance, stability and reliability of the instrument.

13. Communication:RS485,RS232,GPRS/CDMA,Ethernet

14. the USB interface can be configured to export the instrument data to the U disk.

15. Configure with temperature, pressure, and density compensations, and it also has compressibility coefficient compensation for general gas and flow nonlinear compensation.

16. Perfect function of vapor's density compensation, automatic recognition of saturated vapor and superheated vapor and moisture content calculation of wet vapor.

17. Special function for trade settlement.

A.Power down record
