Diesel Fuel Tank Level Gauge Diesel Fuel Tank Water Level Indicator Sensor is intelligent submersible transmitter, this water level sensor consist of isolation diaphragm oil-filled sensor and high-powered MCU. The water level sensor can correct the linearity and compensate temperature drift, have digital output with HART protocol and analog output. The liquid level gauge with characteristic of high precision, good stability. This submersible level sensor can achieve two-way communication during diagnosing process at the scene. This submersible level transmitter apply in city's power supply, water conservancy, metallurgy, petrifaction and so on.
