FG Series Magnetic Float Level Transmitter

FG Series

The FG Series is a magnetic float level transmitter comprising a float and sensing guide rod. The float is sized (volume and weight) based on the density of the fluid to be measured. As the liquid in the vessel travels up and down, the float will rise and fall on the sensing rod. The magnetic float level transmitter has a resistance output directly proportional to float position, fluid level.
