52MM Water Level Gauge with Red Backlight | 0-190 Ohm Water Tank Sensor and Meter

Monitor your water or fuel levels with clarity using this 52mm water level gauge. It comes with a matching 0-190 ohm sensor and a bright red backlight for easy reading in low light. Designed for a range of vehicles and equipment, this gauge helps you keep an eye on your tank levels at a glance.

This universal water level meter is built to handle tough conditions. The gauge features a stainless steel 316L front cover and anti-fog curved glass, offering durability against moisture and temperature changes. The stepper motor inside provides smooth, precise needle movement with low power consumption. With an IP67 waterproof rating, it resists dust and water ingress, making it suitable for engines, generators, boats, and off-road vehicles.

The included liquid level sensor is made from stainless steel and fits diesel or gasoline tanks. It uses the standard European 0-190 ohm output signal. You can choose from multiple sensor lengths, ranging from 100mm to 600mm, to match your tank depth. The sensor comes with a gasket and mounting screws for a secure installation.

Setting up the gauge is straightforward. The wiring harness connects firmly with a snap-together connector, ensuring stable operation even in high-vibration environments. You can also adjust the input resistance by pressing the Mode button on the back, giving you flexibility to match different sender units. The red backlight turns on with your vehicle's lights, keeping the display readable at night.

Key Features and Benefits

- Stainless steel 316L front cover and anti-fog glass that resists corrosion and humidity for long-lasting use

• IP67 waterproof and dustproof rating that protects the gauge in wet or dusty conditions

• Stepper motor drive that delivers accurate readings with less power draw and a longer lifespan

• Ultra-wide 9-32V working voltage that handles electrical fluctuations in cars, trucks, boats, and machinery

• Snap-together harness connector that stays secure under strong vibration, ideal for engines and construction equipment

• Red backlight that makes the dial easy to read in dark cabins or at night

Who Is This For

- Boat owners who need a reliable water or fuel level indicator for their marine tank

• Truck and RV operators who want to monitor auxiliary water tanks from the dashboard

• Off-road and overland enthusiasts who need a rugged gauge that handles dust, water, and vibration

• Mechanics and DIY builders installing a universal level gauge on generators, agricultural machinery, or custom vehicles

Usage Scenario

Mark owns a small fishing boat and often runs trips before sunrise. His old water tank indicator was hard to read in the dark and would fog up in humid weather. He replaced it with this 52mm water level gauge. The red backlight now lets him see the tank level clearly at dawn, and the anti-fog glass stays clear even when the cabin gets steamy. The stainless steel front has held up against saltwater spray without rusting.

Micro Comparison

Many basic water level gauges use plastic housings and standard needles that can fog or stick over time. This gauge uses a stainless steel front, anti-fog curved glass, and a stepper motor for smoother, more reliable needle movement. The IP67 waterproof rating and wide voltage range also make it a more versatile choice for both marine and automotive use compared to entry-level models.
