Magnetostrictive level measurement for filling stations and fuel depots
Magnetostrictive level measurement for filling stations and fuel depots
This document discusses magnetostrictive and wireless technology for liquid level measurement in filling stations and fuel depots. It highlights the use of magnetostrictive level gauges with stainless steel shafts, suitable for various liquids including gasoline, gasoil, LPG, and solvents. The technology supports both wireless and wired communication options.
Specifications
- Magnetostrictive level gauges are available in wireless (battery-powered) and wired (RS485 communication) versions.
- They offer ATEX, CE, IP protection, and OIML compliance, with options for intrinsically safe or explosion-proof versions.
- The gauges support tele-diagnostic functions, remote configuration, and internal sensor replacement without removing the rod from the tank.
- Measuring range: 200 mm to 5,500 mm with accuracy of +/- 0.5 mm and resolution of +/- 0.01 mm.
- Temperature accuracy: +/- 0.2 °C with a resolution of ± 0.0625 °C.
Operating Principle
The magnetostrictive level probe operates on the Wiedemann effect, providing continuous and accurate liquid level readings. It uses a high-frequency electric impulse and a permanent magnet in the float to generate a mechanical impulse, which is measured to determine the float's position.
Certifications
- Explosion proof ATEX certifications: INERIS 06ATEX0051 and CESI 06ATEX 020.
- Intrinsically safe ATEX certifications: CEC 09ATEX131 REV. 3.
- Metrological certifications: OIML R85 for fixed tanks and R80 for mobile tanks.
Wireless Technology
The new generation of magnetostrictive wireless level gauges uses low-frequency wireless technology, offering advantages such as reduced installation costs, low power consumption, and long battery life (up to 5 years).
- Wireless transmission range: up to 2 km line of sight.
- Features include RF repeater, wake-up on radio function, and adjustable power up to 500 mW.
Junction Boxes
- I.S. IP68 Junction Box: High IP rated, suitable for wiring magnetostrictive probes and sensors, with 2 or 4 cable entry versions.
- Ex d IP68 Junction Box: Die-cast aluminum with IP68 protection, suitable for harsh environments.
Additional Components
- Sumps sensor: Detects fluid presence in tank cavities and under dispenser sumps, distinguishing between water and fuel.
- Iron Riser: 2” iron riser for multipoint wiring of probes.
Probes
- I.S. probes XMT-SI-485/RF Series: Intrinsically safe, stainless steel enclosure, suitable for submersion.
- I.S. probes XMT-SI-485 LOG Series: Includes data logger functionality for storing movement data when power or communication is lost.
