  • Introduction
  • Specifications
XSJ-39 series digital flow totalizer is a new type instrument which uses 8039 micro-chip which made by Intel company as the core. It can be used with turbine, vortex, rotary piston, back wheels flow instrument which can products electric pulse signal. It is used in the occasion where need no compensation to realize the following function:
Display the total flow
Display the instantaneous flow
Output volume pulse signal
Output 0~10mA or 4~20mA standard DC signal
Power off data protection
High accuracy, fast response and easy operation
