Bernet High Sensitivity Circular Pulse Output Signal Magnetic Sensor for Fuel Dispenser

Product Description

The magnetic sensor is a high-precision volumetric flow meter widely used in liquid flow measurement across petroleum, chemical, and energy industries. It is particularly suited for fuel dispensers handling viscous fluids like diesel and gasoline. Its operating principle involves a pair of elliptical gears rotating to partition fluid into fixed volumetric units, enabling cumulative measurement with excellent repeatability and resistance to interference.

Technical Specifications (General Fuel Dispenser Applications)

Measurement Range: 0.08–340 m³/h, with port sizes from DN15 to DN1500, accommodating diverse flow requirements.

Accuracy Class: Standard grade 0.5, high-precision grade 0.2, and repeatability error as low as ±0.06%, ensuring reliable fuel dispensing.

Media Compatibility:

Viscosity range: 0.3–50,000 mPa·s, supporting high-viscosity liquids (e.g., heavy oil, lubricants).

Temperature resistance: -40°C to +300°C (extended models for extreme conditions).

Structural Design:

Housing materials: Cast iron, cast steel, or stainless steel, with pressure resistance up to 6.4–10 MPa (cast steel), ideal for high-pressure fuel systems.

Protection: IP66/IP67 ingress protection and explosion-proof rating Ex d IIC T6 Gb, ensuring safe operation in humid or flammable environments.

Signal Output: 4–20 mA current, pulse signals, and RS485 communication (MODBUS protocol) for seamless integration with dispenser control systems.

Advantages & Considerations

Strengths: No straight-pipe installation required; vibration-resistant design; optional built-in lithium battery or external power supply for off-grid applications.

Precautions: Install filters to prevent gear blockage by impurities; unsuitable for aerated liquids without additional gas separators.
