5.4.RTM-register pairing
5.4.1.Programming current register reading (pulse register only)
This feature allows to initialize the current reading of each Port.
RTM Elster AMCO measures, and count pulses coming from the pulse register. It is thus necessary to
establish the link between the reading of the meter given in volume unit (gallon, for example), and RTM
Elster AMCO current reading accessible through radio link.
Example : if the water meter indicates 1000 gallons.
- if the pulse register is from type k = 1 (1 pulse per gallon)
1000 pulses represent 1000 gallons, so the value to be programmed into the RTM current
reading will be 1000.
- if the pulse register is from type k = 10 (1 pulse per 10 gallons)
100 pulses represent 1000 gallons, so the value to be programmed into the RTM current
reading will be 100.
- if the pulse register is from type k = 100 (1 pulse per 100 gallons)
10 pulses represent 1000 gallons, so the value to be programmed into the RTM current
reading will be 10.
