The Wireless Magnetostrictive Level Gauge is an intrinsically safe probe designed for advanced monitoring of underground tanks installed in Zone 0 environments. Using 169 MHz wireless magnetostrictive technology with an integrated battery, it ensures reliable long-distance transmission—up to 3 km—without the need for cabling or excavation. Built in stainless steel and equipped with high-precision floats, it accurately measures product level, water interface, and average temperature. Its compact design, fast installation, and long battery life—up to 7 years—make it a robust and efficient solution for demanding and highly regulated fuel storage applications.
