The Best Choice for Fuel Level Measurement in Gas Stations: Unveiling the 6 Major Advantages of Magnetostrictive Level Gauge
The working principle of magnetostrictive level gauge
Magnetostrictive level gauge operate based on the magnetostrictive effect, where certain materials change length under the influence of a magnetic field. The level gauge consists of a probe rod, a float, and an electronic head. The probe rod contains a magnetostrictive waveguide wire, and the float houses a permanent magnet. During operation, the electronic head emits a current pulse, generating a magnetic field that propagates along the waveguide wire. This interacts with the float's magnetic field, producing a torsional stress wave. By measuring the propagation time of the stress wave, the liquid level height can be precisely calculated.
Advantages of Magnetostrictive Level Gauge
- High Accuracy: Measurement accuracy can reach ±0.5mm, meeting the high demands of gas stations for liquid level measurement.
- High Stability: Unaffected by factors such as medium density, temperature, or pressure, ensuring long-term stability.
- Long Lifespan: No mechanical moving parts, minimal wear, and a service life of over 10 years.
- High Safety: Intrinsically safe and explosion-proof design, suitable for flammable and explosive environments.
- Easy Installation and Maintenance: Simple installation, no need for regular calibration, and low maintenance costs.
- Multifunctional: Capable of simultaneously measuring liquid level, interface, and temperature, with alarm functionality.
