1、 Functional characteristics of intelligent flow totalizer
● Full range automatic temperature and pressure compensation calculation, with any compensation method set
Linear integration and square root integration can be set arbitrarily
Display of various parameters such as instantaneous flow rate, cumulative flow rate, temperature, and pressure
Small signal cut-off function, with a cut-off range of 0-5% optional
The accumulated flow value can be reset by pressing the panel button, and the reset operation can be locked
● Power failure protection function, with accumulated flow value and power failure retention time greater than 5 years, all set values will be maintained for a long time after power failure
Modular structure, combined with powerful instrument chips, makes function combination and system upgrade very convenient
