Applications & Suitability
Diesel Generator (DG) Fuel Tanks: Continuous fuel level monitoring, consumption tracking, and theft prevention for DG sets.
Fuel Storage & Underground Bunkers: Accurate inventory tracking in diesel, petrol, bio-diesel, kerosene, and aviation fuel tanks.
Industrial Oil Reservoirs: Precision monitoring in lubrication skids, hydraulic oil tanks, and turbine governor sumps.
Solvents & Chemical Processing: Safe measurement in ethanol, methanol, toluene, paints, and flammable volatile liquids.
Plastic & Fiberglass Tanks: Grounding tube provides self-contained reference electrode independent of non-metallic tank walls.
The CPLT-1200F provides accurate, continuous process level data to your DCS, PLC, and telemetry systems.
Working Principle of Continuous Fuel Level Transmitter (Diesel, Petrol, Fuels & Solvents)
The CPLT-1200F measures the change in capacitance between a central sensing rod and the outer concentric grounding tube as fuel enters the annular gap.
Because hydrocarbon fuels have a specific dielectric constant (εr ≈ 2.0 to 2.4) compared to air (εr = 1.0), the electrical capacitance varies linearly with the liquid column height.
Advanced digital filtering suppresses sloshing noise, producing an exceptionally smooth 4-20mA signal proportional to fuel depth.
