Flow Totalizer in the Field

Accuracy:
Instantaneous rate: 0.5% of reading
Total rate: 0.1% of reading
Ambient temperature limits: -20 to 60 degree Centigrade

Process temperature limits: -20 to 120 degree Centigrade
Ambient humidity limits : 5 to 95% R.H.
Case material: aluminum alloy
Power supply:3.6V lithium battery (life for 1 year)
      The meter will be into sleep mode when no signal for 1 minute. It will be awoked once appear signal.
Display: 6 digits LCD and engineering units % display mode; Display in engineering unit mode; Totalized flow display mode; Alternate % flow rate and totalized flow display mode; Alternate flow rate in engineering unit and totalized Instantaneous flowrate (engineering unit) and totalized flow display mode, Alternate instantaneous flowrates (in engineering unit Instantaneous flowrates in engineering unit and in % and %) display mode
Non-volatilization: Keep the data in memory when power off
Correction error: Correct the instrumental error in flowmeter characteristics using 1 line-segment approximation (with five correction factors).
Enclosure classification : IP65
Electrical classification:  NEPSI EEx d II BT4
