IMeter deployment
The iMeter is installed on site, where the meter is placed. Before the installation it doesn’t need any
process. The installer only need to know in which meter the iMeter is going to be installed to, in
order to have a pulse captor appropriate for the brand and model of the water meter.
The iMeter can be produced directly connected to the pulse captor, which makes easier and simpler
the deployment process. Also the waterproof properties are better guaranteed in this case.
There is a wide rage of types of places where the water meters are, but the main ones are:
boundary boxes in the ground, or on the buildings front wall or in meter chambers inside the
buildings. The iMeters are mainly used for isolated meters, or meters of special controlling interest
for its big water consumption, which ones are mainly in the ground boundary boxes.
2.1. Connection to a meter and pulse captor
When the installer is in the place of the water meter, the first action that has to be done is the wiring
between the iMeter and the pulse captor. The wiring has to be done according to the technical
characteristics of the pulse captor. It can be found in the pulse captor manual, and the wires must
be connected by functions. The iMeter wires functions are:
•
Brown wire: Ground
•
White wire: Pulses/Positive pulses
•
Yellow wire: Direction/Negative pulses
•
Green wire: Tampering (cable cut detection)
In the following chart there are the main brands and models of pulse captors used, with the color
wires already displayed:
