  • Page 30 User manual 4.4.3. Pulse-binary inputs PV1 to PV4 HydroLogger H1 contains 2 fast pulse inputs labeled PV1, PV2 (terminals 16 and 19) and two slow pulse-binary inputs labeled PV3, PV4 (terminals 21 and 23). All pulse inputs are activated by their connection to the GND ground terminal and therefore the connected sensors must have either an open collector or a potential-free contact (relay contact) at the output.
  • Page 31 The number of pulses per archiving interval is stored along with the pulse weight in the instrument's data memory. From these stored partial flow volumes, the Hydro Logger H1 continuously calculates the total flow volume. The amount of leaked volume since the instrument was installed (or since the channel was initi- alized) is displayed in cyclic mode on the instrument display below the instanta- neous flow rate.
