1 General information
1.1 V purpose of use
The battery/tank monitor BTM can only be operated in conjunction with the shunt SHE-348 on
extra-low voltage DC 8-32V. It is designed for use on yachts and may only be operated in enclosed
spaces protected from rain, moisture, dust and condensation. Never use the battery/tank monitor
in locations where there is a risk of explosion from gas or dust. The battery/tank monitor is not
suitable for outdoor installation.

1.3 RECOMMENDED FUEL SENSORS (not included)
To measure the fill level, we recommend the immersion tube sensor of the TGT or TGW series for
fuel and fresh water as well as the ultrasonic sensor UTV for faeces tanks and the flow rate sensor
DFS (fresh water only). For deep tanks up to 200 cm and a very precise measurement, the pressure
sensor TDS200 (water/diesel/faeces) or TDW200 (water/faeces).
However, these sensors are not included in the scope of delivery.
Sensors from other manufacturers can also be connected. The display is configured to the
connected sensors in SETUP. Furthermore, an adjustment to the tank geometry is possible in order
to correctly display the actual tank content.
Please note: only with the DFS
flow sensors is the litre display accurate, as litres are also measured here. With all
other sensors, this is only a conversion of the measured fill level and, depending on the
sensor accuracy, can never be accurate to the litre!
