Scope of application

The intelligent flow integrator is used in conjunction with all kinds of flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters. The intelligent flow integrator can measure, display, accumulate, alarm, transmit and output data, collect data and communicate all kinds of liquid, steam, natural gas and general gas flow parameters.

Functional characteristics

The intelligent flow accumulator has automatic temperature and pressure compensation operation and the compensation mode is set arbitrarily. Linear integrator and open square integrator are set arbitrarily. A variety of parameters such as instantaneous flow rate, cumulative flow rate, temperature and pressure show that the small signal removal function and the resection range 0-5% are optional.

The accumulative flow value of the intelligent flow accumulator can be cleared through the panel key, the zero operation can be locked, the power failure protection function is accumulated, the accumulative flow value is down for more than 5 years, and all the settings are always maintained after power failure.

The advanced modular structure of the intelligent flow integrator is very convenient for the function combination and the system upgrade with the powerful instrument chip.
