Figure 9A. Example Pulse Signal Hookups to EtherMeter
Setup Via Serial Terminal or Telnet:
When a pulse-based meter input is desired, the user should set the TYPEn parameter to PULSE.
In the example below, the user has set Meter Channel 2 as a pulse-based meter. After TYPEn is
set to PULSE, note that additional user-options become visible on Pg.1 of the Setup Screen. DBn
is a firmware debounce filter setting (see section below), and CNTn is used to synchronize the
EtherMeter’s totalization with that on the meter register (index). PSn (Pulse Scaler) and PDn (Pulse
Divider) are parameters used to scale the pulse count into engineering units. For example, if meter
1 emits 1431 pulses per 1000 gallons, then PD1 should be set to 1431 and PS1 should be set to
1000.
