Bundle: Gauge Only

Overview

This Flush Mount Water Tank Gauge gives you a clean, built-in way to track fresh water levels with a dedicated backlit display. Designed by Topargee in Australia and stocked at our shop in Oregon, it is a strong fit for vans, RVs, trailers, and boats. If you prefer a no-screen option that displays water levels on your phone, see our Bluetooth Water Tank Gauge page. 

This recessed 12V hard-wired gauge uses a polarized backlit display, live liter or gallon readout, and inline hose-line installation so nothing is fitted to the tank itself. It is a good choice for customers who want a permanent, OEM-style installation instead of using a phone app.

Important Info

This gauge tracks water use from the programmed starting amount. After refilling the tank, the unit must be reset so the stored total returns to the programmed value. This unit does not have Bluetooth.

Frequently Asked Questions (click to expand)

1. How does the Flush Mount Water Tank Gauge work?

The sender installs inline on the water line and the display tracks water use from the programmed tank amount. The built-in gauge shows the remaining water in liters or gallons.

2. Does it require drilling into the tank?

No. The sender is installed on the hose line, so nothing is fitted to the tank itself.

3. Is this gauge powered by 12V only?

Yes. This model is designed for 12V hard-wired operation.

4. Where should the sender be installed?

For best results, install the sender about 200 mm after the pump and away from 90 degree elbows. If space is limited, it can be fitted before the pump.

5. Can I switch between liters and gallons?

Yes. The unit can be changed between liters and gallons through the power reconnect procedure described in the installation guide.

6. Do I have to reset it after refilling the tank?

Yes. After refilling the tank, turn the display on and hold the reset button for six seconds so the unit returns to the programmed value.

7. Does it work with gravity-fed and pressurized systems?

Yes. It is suitable for both gravity-fed and pressurized freshwater systems.

8. Can I cut or extend the sender lead?

No. The sender and extension leads should not be cut or joined. Use the proper extension lead if you need more length.

9. What fittings do I need for installation?

The sender has 1/2 in BSP male threads. Many customers use 1/2 in BSP female to 1/2 in NPT male adapters, or other compatible plumbing fittings that suit their hose and system.

10. What happens when the tank runs low or empty?

When the remaining capacity reaches zero or below, the unit gives an audible alert and the display turns red.
