| Reads | Fuel level |
|---|---|
| Resistance | 0–190 ohms (European) or 240–30 ohms (American) |
| Gauge size | 52mm diameter |

| Face | black or white |
| Bezel | black or white plastic, or 316 stainless |
Like all products in the Wema range, our analogue instruments are built to last. Designed to be accurate, reliable and dependable over years of use.
Running out of fuel unexpectedly is, at best, an inconvenience. A fuel gauge you can trust and depend on really matters — and consistent, accurate readings over years of use is what these are designed to deliver.
The IP67 rating means that the gauge is waterproof to up to 1m underwater for 30 minutes and although we hope it never comes to that, it does mean that the gauge is sealed completely from all weather and dust ingress.
Fits any standard 52mm panel cutout. Retrofits straight into most existing dashboards without modification, or drops into any new installation.
Works with any resistance sender of the correct range — Wema S3 or S5, or any sender from another manufacturer with a matching resistance.
Available in European (0-190Ω) and American (240-30Ω) resistance.
Sender and gauge must have the same resistance range — or the gauge will read backwards, or not at all. Not sure which you have? →
Runs on 12V. For 24V systems a dropping resistor is supplied — or a voltage regulator for a cleaner, more stable long-term solution.
Red or amber backlight. Available in black or white face with black, white or brushed stainless bezel — the same styling runs across the full Wema gauge range, so everything matches.
We stand behind our products with a 3-year guarantee.

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).
