Differential Fuel Level Sensor

The DUT-E 2Bio is a differential fuel level sensor.  Designed to measure fuel volume and automatically detect changes in fuel type or quality. Ideal for vehicles and machinery that may operate using blended fuels.  Such as biodiesel or fuels with varying chemical compositions across regions.

It features a third capacitive electrode.  This means the DUT-E 2Bio goes beyond traditional fuel level sensing.  Providing data that not only reflects how much fuel is in the tank but also gives insight into what type of fuel is being used. This feature allows users to identify potential misuse or fuel substitution, protect engine performance, and ensure fuel quality compliance.

DUT-E 2Bio integrates easily into GPS tracking and telematics systems.  In addition, it is powered by the IoT Burger® and S6® technologies.  Therefore, enabling onboard data processing and sensor-to-sensor networking over a single cable.

Key Features

• 🔍 Fuel Type Detection
  Automatically detects changes in fuel composition using a third measuring electrode – perfect for biodiesel monitoring or ensuring fuel consistency across regions.

• 🧠 IoT Burger® Onboard Processing
  Filters and processes raw fuel data inside the sensor, sending only clean and stable information to your telematics platform.

• 🔗 S6 Technology Support
  Easily integrates with other S6-compatible sensors using a single cable for both power and data.  Therefore, ideal for systems with multiple tanks or complex fuel systems.

• 📏 Adjustable Probe Length
  Probes are available in standard sizes (700 mm and 1000 mm).  In addition, they can be cut or extended (up to 6000 mm) to suit your tank depth.

• 🔧 Simple Installation
  Designed for easy mounting with a standard 5-bolt flange and a wide compatibility range for different tank types.

• 🔌 Flexible Output Options
  Available with multiple output signal types including:

  • Digital: CAN J1939/S6, RS-232, RS-485 Modbus

  • Analog: Voltage (1–9 V), Frequency (500–1500 Hz), or Current (4–20 mA).  Analog Outputs are optional and available on placement of order.

• 🌡️ Rugged Design for Harsh Environments
  Built to perform in temperatures from -40°C to +85°C, with excellent protection against overvoltage (up to 100 V) and EMI.

🔧 Customising the DUT-E 2Bio Probe Length

The DUT-E 2Bio sensor probe can be easily adjusted to match the depth of your fuel tank. You can cut the probe to shorten it, or extend it using optional extension sections — up to a total length of 6000 mm. This flexibility makes it suitable for a wide range of tank sizes and applications.
