XSJ**9AI series digital flow totalizer is a new type instrument
which adopts the single-chip as the core. It can be used with
turbine, vortex, rotary piston, back wheels flowmeter which can
product electric pulse signal or standard DC signal to do remote
display and control. It is used in the occasion which does not need
any compensation. It has the following features:
Display instantaneous flow and cumulative flow
Power off data protection function
Two relay contact output
Output 4～*0mA、0～*0mA or l～5V、O～5V Standard DC signal
high accuracy, fast response and easy operation.
