Digital Dual Gauge with Alarm 52MM Water Level and Sewage Level Meter | 0-190ohm Marine Tank Gauge

Monitor your water and sewage levels from a single dashboard gauge. This 52mm digital dual gauge displays both fresh water and holding tank levels with a programmable alarm, giving you clear readings at a glance. Compatible with 12V and 24V systems, it works with 0-190 ohm sensors for a wide range of boats, RVs, and vehicles.

This gauge is built for real-world conditions. It features a built-in 20-second reading delay so splashing water in the tank does not cause erratic readings. The high-resolution LED screen stays visible even in direct sunlight, and the IP66 waterproof rating ensures reliable operation in marine and outdoor environments. You can program the input resistance signal to match different sensor types including 0-190 ohm, 0-180 ohm, 10-180 ohm, 240-33 ohm, and 240-30 ohm.

Installation is straightforward. The gauge fits into a standard 52mm (2-inch) panel cutout, and the included wiring harness connects to your power source and sensors. The gauge is sold individually and does not include a sensor. If you need a sensor, it is available separately. The package includes the gauge, a user manual, and a wiring cable.

This dual gauge replaces the need for two separate meters, saving space on your dashboard. Whether you are managing fresh water and waste tanks on a boat, motorhome, or truck, this single unit gives you the information you need without clutter.

Key Features and Benefits

- Dual display shows both water level and sewage level on one gauge that saves dashboard space and simplifies monitoring

• Programmable input resistance from 0-190 ohm to 240-30 ohm that allows compatibility with various sensor types

• Built-in 20-second reading delay that prevents false readings from water splashing inside the tank

• High-resolution LED screen that remains readable under direct sunlight for clear visibility at all times

• IP66 waterproof rating that protects the gauge from water spray and harsh marine conditions

• Reverse polarity protection that prevents damage from incorrect wiring during installation

Who Is This For

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

• RV and motorhome users who want a clean dashboard setup without multiple separate meters

• Truck and hot rod builders who require a compact tank level monitoring solution for custom builds

• Generator operators who need reliable tank level readings in outdoor or industrial environments

Usage Scenario

Mark spends weekends on his cabin cruiser with his family. Before this gauge, he had to check two separate meters to see if the fresh water tank was getting low and if the holding tank was getting full. After installing this dual gauge, he can see both levels on one screen. The alarm alerts him when the sewage tank approaches capacity, so he knows exactly when to pump out. No more guessing or checking multiple locations.

Micro Comparison

Traditional tank gauges require one meter per tank, taking up twice the dashboard space and requiring separate wiring. This dual gauge combines both readings into a single 52mm unit, reducing installation time and simplifying your panel layout. The programmable signal range also means you are not locked into a single sensor type, giving you more flexibility compared to fixed-resistance gauges.

Questions and Answers

Question: Does this gauge work with both fresh water and sewage tanks at the same time?

Answer: Yes, the gauge has two independent inputs. One displays water level and the other displays sewage level, both on the same screen.

Question: What size hole do I need to cut for installation?

Answer: You need to cut a 52mm (2-inch) diameter hole. The gauge fits standard 52mm panel cutouts.

Question: Does the gauge come with a sensor?

Answer: No, the gauge is sold separately. The package includes the gauge, manual, and wiring cable. Sensors are available as separate items.

Question: Can I use this gauge with a 0-180 ohm sensor?

Answer: Yes, the gauge is programmable. You can set it to work with 0-190 ohm, 0-180 ohm, 10-180 ohm, 240-33 ohm, or 240-30 ohm sensors.

Question: How long does it take for the reading to update when the tank level changes?

Answer: The gauge has a built-in delay of about 20 seconds. This prevents the display from jumping around due to water splashing inside the tank.

Question: Is this gauge suitable for use in a marine environment?

Answer: Yes, it has an IP66 waterproof rating and is designed for marine boats, trucks, RVs, and other vehicles exposed to moisture.

Question: What voltage does this gauge work with?

Answer: It works with both 12V and 24V DC systems.
