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 (0–190Ω) and American (240–30Ω) 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 0–190Ω or American 240–30Ω
- 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
Fitting: 52mm cut-out, with at least 55mm clearance behind the panel.
Need the matching sender? Browse level senders →. Running 24V? Feed the dashboard from a voltage regulator → for a steadier supply (why this matters →), or browse all level gauges →.
The gauge has a 5-pin connector:
1. Blue — 12V negative (ground)
2. Red — 12V positive (fused, via the ignition or a separate switch)
3. Black — to the sender
4. Orange — red backlight
5. Yellow — amber backlight
Connect either the Orange or the Yellow wire for backlighting — the wire colour matches the backlight colour. The backlight is dimmable.
Fitting on 24V: either fit a voltage regulator (12V output) ahead of the gauge, or wire the supplied 150Ω dropping resistor in line with the 12V positive feed.
1. Cut a 52mm (2 1/16") diameter hole in the panel. You will need a minimum clearance of 55mm (2 3/16") behind the panel to fit the gauge. The panel can be 1–20mm thick.
2. Remove the fastening ring, insert the gauge through the panel from the front, then fit and tighten the fastening ring from the rear.
3. Connect the wiring as shown in the wiring diagram, selecting either the Orange or Yellow wire for your preferred backlight colour.
4. Securely connect the plug into the port at the back of the gauge.

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).
