Key Features & Technical Highlights

The Sensor is designed to measure the fuel level in reservoirs and fuel tanks of vehicles as well as in stationary fuel storage facilities. The Sensor can be used to measure the level of other non-electrically conductive liquids. The fuel level is measured by a measuring head integrated into a single unit with a probe immersed in the fuel. The measuring probe performs the function of a capacitor, the capacity of which depends linearly on the fuel level in the tank.

Why Choose Mercetech SP-BLE Fuel Level Sensor?

1. Wireless Fuel Monitoring with BLE Technology

The SP-BLE utilizes Bluetooth Low Energy (BLE) to transmit fuel level data wirelessly to compatible GPS trackers, telematics systems, or Bluetooth sensor readers. This simplifies installation, eliminates wiring failure risks, and supports long-range data communication (typically up to 20 meters).

2. Real-Time & High-Precision Fuel Measurement

Powered by capacitive sensing technology, the SP-BLE sensor measures fuel level with extremely high resolution and linearity. The fuel level is converted into a corresponding capacitance reading by the probe, enabling accurate digital data that provides reliable insight into fuel volume and consumption patterns.

3. Built-In Calibration & Galvanic Isolation

This fuel level sensor includes an internal calibration table that allows measurement output to be translated directly into litres, eliminating guesswork and manual conversions. Additionally, galvanic isolation protects the sensor electronics from power surges and electrical noise, ensuring stable performance over time.

4. Long-Lasting Performance & Battery Efficiency

The unit operates on a low-power lithium battery (3.6 V) designed for multi-year continuous usage. BLE communication further reduces power consumption, making it ideal for remote or hard-to-reach fuel tanks.

5. Easy Installation & Versatile Probe Length

Installation is simple and adaptable. The probe can be cut to suit varied tank depths — from 15 cm up to 300 cm — using basic tools, ensuring quick setup in diverse vehicles or fuel storage settings.

6. Broad Compatibility

The SP-BLE transmits data to any BLE-enabled device. For systems without built-in BLE support, a compatible BLE sensor reader can bridge the connection via RS-232, RS-485, or USB interfaces, making SP-BLE suitable for both modern telematics and legacy systems.

Applications & Use Cases

Fleet & Transport Management

Keep accurate track of fuel levels across fleets — from trucks to heavy machinery. This sensor enables fleet managers to detect abnormal fuel decreases, optimize fueling schedules, and reduce fuel costs.

Stationary Fuel Storage

Ideal for monitoring fuel tanks at construction sites, generator farms, and backup power systems without wiring complexity.

Industrial & Remote Assets

Equip stationary industrial systems or unmanned assets (like remote off-grid generators) with continuous fuel level monitoring to prevent downtime and plan refills efficiently.

IoT & Telemetry Integration

Connect with IoT dashboards or telematics platforms to view historical trends, generate alerts, and derive actionable insights into fuel consumption and asset utilization.
