Boat digital tank level display
TCM 1 / 2 philippi elektrische systeme

The well readable digital tank monitor TCM shows a clear overview of the filling conditions of up to four tanks, e.g. a water, a fuel and a waste water tank. The measuring of liquid levels resulted by proven immersion tubes TGT/TGW that are available in different lengths or with ultrasonic sensors series UTV. Older level sensors series TRG or level sensors with different characteristics (240-33 Ohm, 0-90 Ohm,...) can also be connected. Active level sensors with current output 4-20 mA are also connectable after a hardware-adjustment. The tank monitor TCM 2 calculates the water tank level by a flow rate sensor DFS. The calculation of the level is made by a math-integration algorithm. The fill up reset (100%) is made just by pressing a key when the tank is fully. The TCM 4 can be used for up to 2 flow sensors.
The tank symbols can be choosen individually by the setup. An interval measurement procedure reduces the power consumption to a minimum. In case the voltage comes below 12 V, the measurement interval increases to reduce the power consumption.

The size of the individual tank can be stored in the setup, so the measuring value can be shown in liters or in percentage. Please keep in mind that because of the limited resolution of the sensors, the shown liters/level will never be exact. To adjust the displayed level to non-rectangular tanks a correction factor can be set in the setup for each tank.
