Digital Dual Gauge with Alarm 0-190ohm 52mm | Water Level and Sewage Level Meter for Marine and Vehicle

Monitor both water and sewage levels in your boat, RV, or vehicle with a single 52mm digital gauge. This dual-purpose meter works with 0-190 ohm sensors and includes a programmable alarm to alert you when levels reach critical points. The bright LED display stays readable even in direct sunlight, making it a practical choice for marine and automotive use.

This gauge is designed for easy installation into a standard 52mm panel cutout. It features reverse polarity protection and an anti-fogging display for reliable performance in demanding environments. The unit is IP66 waterproof rated, so it can handle splashes and moisture without issue. A built-in 20-second delay prevents false readings from liquid movement inside the tank.

The gauge is fully programmable. You can set the input resistance range to match different sensors, including 0-190 ohm, 0-180 ohm, 10-180 ohm, 240-33 ohm, and 240-30 ohm. This flexibility allows it to work with various fuel, water, and temperature sensors. The top and bottom rows can be configured independently, letting you monitor two different tank levels on one display.

Please note that this listing is for the gauge only. Sensors are sold separately. If you need both the gauge and sensor, be sure to add both to your cart when placing your order. The gauge works with 12V or 24V systems and operates in temperatures from -40 to 85°C.

Key Features and Benefits

- Dual display shows water level and sewage level on one gauge for space-saving installation

• Programmable input resistance from 0-190 ohm to 240-33 ohm adapts to different sensors

• Built-in alarm alerts you when tank levels reach critical points for proactive management

• IP66 waterproof rating protects against moisture and splashes in marine environments

• 20-second reading delay prevents false alarms from liquid movement inside the tank

• Reverse polarity protection and anti-fogging display ensure reliable long-term performance

Who Is This For

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

• RV and motorhome users looking for a clear, sunlight-readable tank level display

• Truck and bus operators who want a durable gauge for water or sewage monitoring

• Custom vehicle builders installing a multifunctional level monitoring system

Usage Scenario

Mark owns a 35-foot cabin cruiser and was tired of checking two separate gauges for his fresh water tank and holding tank. He replaced both with this single 52mm dual gauge. Now he can see both levels at a glance, and the alarm lets him know when the holding tank is nearly full before it becomes a problem. The sunlight-readable display means he can check levels even on bright summer days without shading the screen.

Micro Comparison

Unlike single-function analog gauges that only display one tank level and offer no alerts, this digital dual gauge shows both water and sewage levels in one unit. The programmable alarm gives you an extra layer of awareness that standard meters lack. Its IP66 rating and wide operating temperature range make it more suitable for harsh marine and vehicle environments than basic automotive gauges.
