A direct-reading level gauge for fuel or water tanks that needs no electrical power — useful where there's no supply, or where you simply want an independent read that doesn't depend on the electrics. You read the level straight off the dial at the head of the gauge.

It's suitable for water, diesel or petrol. The nylon head and aluminium body resist corrosion and chemical exposure, and it comes in lengths from 110mm to 1500mm to match your tank depth.

• Mechanical level gauge — no power required
• For water, diesel or petrol
• Lengths 110–1500mm (choose to suit tank depth)
• Nylon head, aluminium body — corrosion and chemical resistant
• 1.5" BSP threaded fitting
• IP64 — sealed against dust and splashing water

Mounting is a 1.5" BSP thread. Where you can't thread directly into the tank, the FL-6 fitting flange bolts to the tank top and provides a 1.5" female thread to take the gauge. Custom lengths and mountings are available to order (minimum 10).
