VISUAL TANK LEVEL WITHOUT BATTERIES OR WIRING
850mm mechanical level gauge with DN40 (1.5 BSP M) fitting. Direct visual read of tank contents without power or sensors.
No-power monitoring
The Fozmula mechanical gauge uses a float arm and dial. No 12V supply to wire in, no sensor to corrode, no gauge cluster to program. Mount it in your tank port, tighten the 1.5 BSP male thread, and the dial tells you how full the tank is. That simplicity matters on AgChem rigs and small fuel trailers where you don't want another electrical fault to chase.
850mm for shallow tanks
This probe length suits bunded diesel tanks under a metre deep, workshop oil drums with BSP bungs, and compact water carts. Measure your tank depth before you order. If the probe is too short you'll never see the bottom quarter; too long and it fouls the sump or baffle.
