Description
The intelligent flow accumulator adopts microcomputer chip and technology, which is used in conjunction with all kinds of flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters. It can measure and display, accumulate calculation, alarm control, transmission output, data acquisition and communication of various flow parameters such as liquid, steam, natural gas, general gas and so on.
Functional characteristics
Automatic temperature and pressure compensation, compensation mode arbitrarily set
Arbitrary setting of linear product calculation and open square product calculation
Instantaneous flow rate, cumulative flow rate, temperature and pressure are displayed at the same time.
Small signal resection function, resection range0-5% optional
Cumulative traffic can be cleared by the panel button, zeroing operation can be locked
Power down protection function, cumulative flow value power down protection time is greater than10 years, after the set value is turned off, keep.
Modular structureIt is very convenient to cooperate with the function combination and system upgrade of instrument chip.
