Geotech PVT Remote Gateway.2.5
Fig. 2 – PVT Remote Gateway with optional mounting bracket for 1” pipe.
The standard gateway supports up to 8 connected piezometers and comes encased in a plastic cabi-
net/box including a rechargeable battery with capacity for 6 months. Power consumption calculation is
based on time between loggings=1 hour; time between sending log file to the server=12hours. Capacity
might be reduced if used in very cold environment. If you need longer time between visits or more fre-
quent loggings/updates, we suggest installation of the optional photovoltaic solar panel.
Fig. 3 – PVT Remote Gateway comprising small box with electronics, battery, antenna and termi-
nal block.
The equipment comprises an internal casing with all electronics (below “small box”). The small box should
only be opened under dry conditions for installation of your SIM card. It is protected inside an external
casing (below “big box) together with terminal blocks, battery and antenna. A thin plastic hose connects
the built-in air pressure sensor with the external atmosphere.
