Never worry about running out of fresh water or overflowing tanks again. This Marine Water Level Sensor & Gauge Kit gives you real-time, accurate tank level monitoring directly on your dashboard — eliminating guesswork, preventing dry-pump damage, and saving you from costly overflows. Whether you're on a boat, RV, or off-grid vehicle, this kit is your essential water management solution.

Why You Need This Kit

  • Prevent dry-run pump damage — know your water level before the pump runs dry
  • Avoid tank overflow — monitor fill levels in real time
  • Easy dashboard reading — analog gauge with backlit display, readable day or night
  • Wide voltage compatibility — works with 9–32VDC systems (12V & 24V boats/RVs)
  • Durable stainless steel sensor — corrosion-resistant, built for marine environments
  • Multi-color backlight — 6 backlight colors (Red/Green/Blue/White/Yellow/Cyan + Auto cycle)

How It Works

The sensor uses a ferrite magnet and reed switch (干簧管) mechanism: as the float rises and falls with the liquid level, it triggers the reed switch to output an electrical signal proportional to the tank level. This signal is sent to the analog gauge, which displays the current water level on a clear dial face.

Kit Contents

  • 1× Stainless steel water level sensor (available in 15/20/25/30/35/40/50cm lengths)
  • 1× 52mm analog water level gauge with multi-color backlight
  • Wiring harness

Gauge Wiring (5-Wire)

  • ① Black — Ground (–)
  • ② Red — Power 9–32VDC (+)
  • ③ Blue — Signal input (from sensor brown wire)
  • ④ Yellow — Backlight power
  • ⑤ White — Backlight color adjustment (short to ground to cycle colors)

Sensor Wiring

  • Blue wire — Power negative (–)
  • Brown wire — Signal output → connect to gauge terminal ③ (blue)
