Digital flow Indicator flow totalizer meter

 

1.Production introduct

 

  Flow totalizer collects, displays, controls, transmits, communicates and prints all kinds of signals such as temperature, pressure and flow. It forms a digital acquisition system and control system. It is suitable for flow accrual measurement and control of various liquids, general gases, superheated steam and saturated steam.

 

2. Product Features

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

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

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

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

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

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

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

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

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

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

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

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

l Communication

  RS485

  RS232

  GPRS/CDMA

  Ethernet

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

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

l Special function for trade settlement.

  Power down record

  Timing meter reading

  Query function on some illegal operations.

  Printing

l Display unit can be modified according to different requirements.

l Large storage function.

  Day record can be stored in 5 years

  Month record can be stored in 5 years

  Year record can be stored in 16 years
