VISUAL TANK LEVEL READING WITHOUT POWER OR WIRING
500mm mechanical float gauge with DN40 (1.5 inch) BSP male thread. Direct visual level reading for fuel and fluid tanks.
Simple mechanical operation
Float rises and falls with the fuel level. Dial indicator shows the position in real time. No electronics, no calibration, no wiring to run. Install it in the tank fitting and read the level at a glance. Suits diesel, petrol, AdBlue and oil tanks across workshops, construction sites and mobile refuelling setups.
Standard BSP fitting
DN40 (1.5 inch) BSP male thread is the common Australian tank standard. 500mm probe length suits tanks up to half a metre deep. If your tank uses a standard BSP boss, this gauge threads straight in. No adapters, no custom fittings to hunt down.
