1. Features of intelligent flow totalizer

● Full-range automatic temperature and pressure compensation calculation, the compensation method can be set arbitrarily

● Linear accumulation, square root calculation can be set arbitrarily

● Display of various parameters of instantaneous flow, cumulative flow, temperature and pressure

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

● The accumulated flow value can be reset by the panel button, and the reset operation can be locked

● Power-off protection function, the cumulative flow value is kept for more than 5 years after power-off, and all the set values are kept for a long time after power-off

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