I – Overview
GESTAG is a water telemetry system composed of field units
connected to pulsed water meters and a web management
platform. Each unit records flow pulses and transmits
these data over the cellular network (3G/M2M or Wi-Fi) to
the central system.
The architecture is modular: you can start with a few
points and expand as the project grows, without the need
for major civil interventions or complex cabling.
II – Components and functions
-
GESTAG Unit: electronic module
responsible for counting water meter pulses, storing
data temporarily, and transmitting them over the
cellular network.
-
Pulsed water meter: water meter with
pulse output proportional to the measured volume.
-
Power source/battery: unit power supply,
dimensioned for high autonomy.
-
Management platform: web environment
where data is consolidated, displayed on dashboards,
and exported into reports.
III – Electrical signal topology
Each GESTAG is connected to the water meter's pulse contact
using low-voltage cables. The connection must follow the
meter manufacturer's instructions, respecting polarity,
shielding, and maximum recommended distances.
In larger projects, it is possible to organize interconnection
panels and separate conduits for instrumentation signals,
avoiding interference with power cables.
IV – Data Flows and Calculations
With each registered pulse, GESTAG internally updates the
consumed volume. Periodically, these data are transmitted
to the central system, which converts pulses into m³ or
liters, aggregating by minute, hour, day, month, and other
configurable periods.
From the consolidated base, consumption charts,
unit comparisons, alarms, and automatic reports are generated.
V – Installation best practices
- Plan the positioning of modules and antennas.
-
Ensure easy access to points for future maintenance.
-
Protect wiring against moisture, excessive heat, and
mechanical damage.
-
Clearly identify each meter and its respective
monitored point.
VI – Bill of Materials
The typical bill of materials includes GESTAG units,
pulsed water meters, signal cables, power supplies,
conduits, junction boxes, and fixing elements. Exact sizing
depends on the number of points and the hydraulic layout
of the project.
