Continuous Level Measurement

F78MP Series Radar

The F78MP Series air radar sensor provides non-contact, continuous level measurement for bulk materials in bins, tanks and silos. Accurate and reliable in difficult environments, the F78MP Series is an ideal level meter for powder and bulk solid inventory management. The F78MP Series air radar withstands corrosive environments and takes consistent measurements in steam, dust and other turbulent conditions.

The F78MP Series air radar measures the level of material in a bin or silo by monitoring the time it takes for an emitted microwave pulse to travel from the level meter to the surface of the material being measured and back to the meter. This time is calculated into distance which is then translated into a level measurement.

Ideal for Difficult Environments

Transmitting at a frequency of 78 GHz with a narrow beam angle of 4 degrees, the F78MP Series air radar level device is consistent and accurate in difficult environments.

Optimal Positioning

To receive the best results, a directional (5 degrees), or aiming flange (10 degrees) is offered on the F78MP Series air radar, which allows the unit to be directed specifically at the desired location within the vessel. A flat flange is also available.
