Green LED Digital 2 IN 1 52mm Gauge with Alarm | Water Level and Sewage Level Meter for 12V/24V Vehicles

This 2 in 1 digital gauge lets you monitor both water and sewage levels from a single 52mm display. It works with a 0-190 ohm signal range and includes programmable alarm settings to alert you when levels are too low or too high.

Designed for marine boats, trucks, RVs, and generators, this gauge provides clear green LED readouts that are easy to see even in direct sunlight. The dual function design saves dashboard space and simplifies your monitoring setup.

The gauge features a built-in delay of about 20 to 80 seconds. This prevents false readings from liquid splashing inside the tank, giving you more accurate and stable level information.

Installation is straightforward with color-coded wiring and a standard 52mm cutout. The unit works with both 12V and 24V electrical systems and includes reverse polarity protection for added safety.

Key Features and Benefits

- 2 in 1 dual function that monitors water level and sewage level from one gauge, saving panel space and reducing installation work

• Green LED digital display with high resolution that stays readable under bright sunlight, so you can check levels at a glance

• Programmable alarm set below 20% for water level and above 80% for sewage level, giving you clear warnings when action is needed

• Adjustable input signal range from 0-190 ohm with multiple preset options, making it compatible with different tank sensors

• IP66 waterproof rating and anti-fogging performance, ensuring reliable operation in wet and humid environments

• Wide working temperature range from -40 to 85°C, suitable for extreme weather conditions

Who Is This For

- Boat owners who need to monitor fresh water and waste tank levels from a single dashboard gauge

• RV and motorhome users looking for a compact dual-purpose level indicator for holding tanks

• Truck and bus operators who want a reliable water and sewage monitoring system for mobile living spaces

• Generator technicians requiring a durable level gauge that works in both 12V and 24V electrical systems

Usage Scenario

Mark owns a small motorhome and often camps off-grid for several days. He used to check his fresh water and waste tanks separately with two different gauges, which was inconvenient and took up space on his dashboard. After installing this 2 in 1 gauge, he can see both levels on one screen. The alarm reminds him when his fresh water drops below 20% and when his waste tank reaches 80%. This helps him plan his water usage and find a dump station before the tanks become a problem.

Micro Comparison

Unlike basic single-function gauges that only monitor one tank, this 2 in 1 unit displays both water and sewage levels from the same 52mm opening. It also includes programmable alarms and multiple signal range options, giving you more flexibility than standard fixed-range gauges. The green LED display offers better visibility in bright conditions compared to analog needle gauges.
