JMG Magnetic Level Gauges are a safe, economical way to measure and control level through a wide range of process pressures, temperatures, and fluids. Each component of the JMG (chamber, float, and indicator) has been engineered to improve on existing designs to ensure reliable, maintenance-free operation right out of the crate. The JMG can be coupled with an MGT magnetostrictive level transmitter and/or any Jogler level switch to provide control outputs configured to specific customer needs.
