I. Function characteristics of intelligent flow integrator

● Full range of automatic temperature and pressure compensation operation, compensation mode can be set arbitrarily

● Linear product, square product, arbitrary setting

● Instantaneous flow, cumulative flow, temperature, pressure and other parameters display

● Small signal excision function, excision range 0-5% optional

● The accumulated flow value can be cleared by the panel key, and the clearing operation can be locked

● Power failure protection function, the cumulative flow value power failure retention time is greater than 5 years, all the set values after power failure to maintain for a long time

● Modular structure, with powerful instrument chip, function combination, system upgrade is very convenient
