The TankMinders will give you ample warning before your black water holding tank needs emptying.




Tankminder Waste Tank Level Indicator

Robustly made from a stainless steel, compact, 20 cm long tank level indicator. This sender works on the simple principle of twin magnets in the float activating two thresholds on a PCB board securely housed and doubly insulated inside the stainless steel tube. Designed to be fitted into the top surface of a tank with an 1 ¼” BSP thread.
The sender simply screws into the threaded fitting allowing for a quick and easy removal for inspecting and cleaning.
If fitted by Tek Tanks then a machined 1 1/4″ BSP female threaded socket is welded directly to the tank.

TankMinder 1 allows you to connect the sender to a single light panel, you can bring the signal on at approximately 9 or 15 cm from the top of the tank depending which wire you connect.

TankMinder 3 gives you a 3 light LED gauge giving you appropriate readings before you need to empty your tank.
Green shows the tank has plenty of capacity.
The yellow light will then come on indicating the level is 15cm from the top.
Finally the red light will come on indicating that the tank is 9cm from the top and will require emptying.
