0-190 ohm Car Boat Digital Voltage Meter Voltmeter Ammeter Fuel Gauge with A5 Oil Tank Level Meter Sensor 100~500mm DC 12V 24V

Keep an eye on your fuel level and battery voltage at the same time with this 2-in-1 digital gauge. It combines a voltmeter and a fuel gauge in one compact display, making it a practical addition to any car, boat, or RV dashboard. The included A5 oil tank level sensor works with standard 0-190 ohm senders for accurate readings.

This gauge is built to handle tough conditions. It operates on DC 9-36V power and works in temperatures from -40 to 50 degrees Celsius. The voltage meter measures from 10 to 39V with a precision of plus or minus 0.1 percent. It also includes a flashing alarm that triggers when voltage drops below 10V, goes between 16 and 20V, or rises above 31V, helping you catch electrical issues early.

The fuel level sensor measures resistance from 0 to 190 ohms, with empty at 0 ohms and full at 190 ohms. It comes in lengths from 100 to 600 mm and is rated IP67 for dust and water resistance. The sensor can handle operating temperatures from -40 to 85 degrees Celsius, so it performs reliably in harsh environments. The gauge also supports oil resistance ranges from 5 to 1000 ohms with a measurement accuracy of plus or minus 1 percent and flashes an alarm when fuel drops below 10 percent.

Installation is straightforward with the 5-hole mounting design. The sensor uses five M5 screws and a 2 mm thick gasket for a secure fit. Whether you are upgrading an old gauge or setting up a new system, this kit gives you the essential tools to monitor both fuel and voltage in one glance.

Key Features and Benefits

- 2-in-1 gauge design that displays voltage and fuel level together, so you do not need separate instruments on your dashboard.

• Wide voltage measurement range from 10 to 39V with high accuracy of plus or minus 0.1 percent, giving you reliable electrical system monitoring.

• Flashing alarm for low voltage, mid-range voltage, and high voltage conditions, alerting you to potential battery or alternator problems.

• Fuel level sensor with 0-190 ohm signal range and IP67 protection, ensuring accurate readings even in wet or dusty environments.

• Broad operating temperature range from -40 to 85 degrees Celsius for the sensor, making it suitable for extreme climates.

Who Is This For

- Boat owners who want a single gauge to monitor both fuel level and battery voltage on the water.

• Car enthusiasts upgrading their dashboard with a digital display that provides real-time electrical and fuel data.

• RV and campervan users who need reliable fuel level monitoring and voltage alerts during long trips.

• DIY mechanics and technicians installing a replacement gauge system for older vehicles or custom builds.

Usage Scenario

Mark runs a small fishing boat and was tired of guessing how much fuel he had left. After installing this 2-in-1 gauge, he can see both his fuel level and battery voltage at a glance. On a recent trip, the voltage alarm flashed when his alternator started failing, giving him enough time to head back to the dock before the battery died. The fuel level sensor also helped him plan his trips better, so he never runs out of gas in the middle of the lake.

Micro Comparison

Unlike basic fuel gauges that only show fuel level, this unit combines a voltmeter and fuel gauge in one device. It also includes voltage alarms that many standalone fuel meters lack, giving you early warnings for electrical problems. The IP67-rated sensor adds extra durability compared to sensors with lower protection ratings.
