Features of AJ Flow Meter Totalizer /flow indicator totalizer

Suitable for flow (Heat) displaying, flow rate totalizer,calculating and controlling of all kinds of liquids, water, acid, chemical solutions, single or mixed gases and vapor,saturated steam,superheated steam，natural gas, compressed air. It is flow rate totalizer.
Input multiple flow sensor signals (Such as VSF,vortex flow meter , Turbine flow meter , Electromagnetic flow meter, Roots, Elliptical gear, Duplex rotor, Orifice plate flow meter ,V-cone, Annubar, and Thermal mass flowmeter, etc.). it is universal flow monitors.AJ series flow indicator totalizer can be water flow totalizer,steam flow totalizer, fuel oil flow totalizer,gas totalizer,natural gas flow meter totalizer.
Flow indicator totalizer input channel: Receive frequency and multiple current signals (4-20mA).
Totalizer meter has pressure and temperature input channel: Receive multiple current signals. It is steam/gas flow controller with temperature and pressure compensation calculation.
Provide 24VDC and 12VDC power supply with short circuit protection, simplify the system and save investment.
Fault-tolerance: When the compensation measurement signals of temperature, pressure or density are abnormal, compensate with the manual setting of the corresponding operation.
Circular display: Provide convenience to monitor multiple process variables, not just a flow counter, can also indicate temperature and pressure information when the signals are connected to our flow totalizer indicator.
The update cycle of output current signal is 1 second, which can meet the requirements of the automatic control.
Configure with Instrument clock, automatic meter reading and print function, provide convenience for metering management.
Self-test and self diagnosis makes the flow rate totalizer easier to use and maintain.
3 -level password to prevent unauthorized personnel to modify parameters.
There are no potentiometer, code switch and other adjustable devices, that can improve the vibration resistance, stability and reliability of the flow totalizer.
Communication
