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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eSetting 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.\u003c\/p\u003e\n\u003cp\u003eKey Features and Benefits\u003c\/p\u003e\u003cp\u003e- Stainless steel 316L front cover and anti-fog glass that resists corrosion and humidity for long-lasting use\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eIP67 waterproof and dustproof rating that protects the gauge in wet or dusty conditions\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eStepper motor drive that delivers accurate readings with less power draw and a longer lifespan\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eUltra-wide 9-32V working voltage that handles electrical fluctuations in cars, trucks, boats, and machinery\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSnap-together harness connector that stays secure under strong vibration, ideal for engines and construction equipment\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eRed backlight that makes the dial easy to read in dark cabins or at night\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWho Is This For\u003c\/p\u003e\u003cp\u003e- Boat owners who need a reliable water or fuel level indicator for their marine tank\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eTruck and RV operators who want to monitor auxiliary water tanks from the dashboard\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eOff-road and overland enthusiasts who need a rugged gauge that handles dust, water, and vibration\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eMechanics and DIY builders installing a universal level gauge on generators, agricultural machinery, or custom vehicles\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eUsage Scenario\u003c\/p\u003e\u003cp\u003eMark 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.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eMany 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.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003e- Material: Stainless steel 316L + plastic + anti-fog glass\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eGauge diameter: 52mm \/ 2-1\/16 in\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eBacklight color: Red\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eWorking voltage: 9-32 VDC\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eInput signal: 0-190 ohm\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eWorking current: ≤60mA\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eOperating temperature: -30°C to +75°C \/ -22°F to +167°F\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eStorage temperature: -40°C to +85°C \/ -40°F to +185°F\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eProtection grade: IP67\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eItem colors available: Black, White, Silver black\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor material: Stainless steel\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor output signal: 0-190 ohm (standard European)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor length options: 100mm to 600mm (contact seller to choose)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor assembly: SAE standard 5 holes\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor operating temperature: -40°C to +85°C \/ -40°F to +185°F\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eSensor rated current for alarm switch: 500mA\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eItem weight: 0.15 kg \/ 5.3 oz\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003ePlease allow 1-3 cm \/ 0.4-1.2 in difference due to manual measurement.\u003c\/p\u003e\n\u003cp\u003ePackage Includes\u003c\/p\u003e\u003cp\u003e- 1 x Water gauge\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e1 x Wiring harness\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e1 x Installation instruction\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e1 x Water level sensor\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e1 x Gasket\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e5 x Screws\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWhy You Will Love It\u003c\/p\u003e\u003cp\u003eYou get a complete water level monitoring kit in one box, from the gauge to the sensor and mounting hardware.
