A 52mm analogue gauge for keeping an eye on your water tank level at a glance. It works with resistance senders — the Wema S3 and S5, or any other sender with a matching resistance range — reading steadily as the tank fills and empties.
It's available in both European (0–190 or 10–180 ohms) and American (240–30 ohms) ranges. The gauge and sender must share the same range to read correctly — European vs American resistance explained → shows how to check before you order.
- 52mm analogue water level gauge
- Pairs with S3, S5 or any matching resistance sender
- European 0–190 or 10–180 ohms, or American 240–30 ohms
- Red or amber backlight, wire-selectable
- 12V or 24V (24V needs a dropping resistor or voltage regulator)
- IP67 — sealed against dust and water
- Choice of black or white face, with a stainless, black or white bezel
- Backed by a 3-year guarantee
Fitting: 52mm cut-out, with at least 55mm clearance behind the panel.

Fitting on 12V or 24V — and why a voltage regulator helps
A 12V system is never a steady 12V: it sags under load, rises to 14V or more on charge, and spikes as things switch on and off. The gauge sees all of it, so readings can wander with the state of the electrics rather than with what you’re measuring. A voltage regulator delivers a clean, steady voltage whatever the supply is doing — so the gauge reads consistently, the backlight stays even, and sensitive electronics are protected from spikes.
On a 24V system a dropping resistor is supplied to suit the gauge, but a regulator is the better option: resistors run hot, waste power and add a failure point at each gauge, whereas one regulator feeds the whole dashboard from a single clean supply (the 3A model runs up to 20 standard 52mm gauges, the 5A up to 38).
