Liquid Level/Material Level Measurement Principle

Radar level transmitters measure liquid level or material level by emitting microwave pulses and receiving echoes. The instrument calculates the distance based on the time difference between the transmitted wave and the echo, and then converts it into the liquid level height. The FMR50 series is suitable for a variety of working conditions, and the measurement results are affected by factors such as dielectric constant and installation position.

Key Operation Instructions

The instrument is equipped with three keys: "+", "-", and "E". Proper use of the keys enables efficient parameter setting and menu switching.

Detailed Key Functions

  • "+" plus key: Moves down through options in a selection list; moves forward to select menu items in an input menu.
  • "-" minus key: Moves up through options in a selection menu; moves back to select menu items in an input menu.
  • "E" confirm key: Opens a submenu or parameter, and confirms the changed parameter value.

Combination Key Operation

  • Press "+" and "-" simultaneously: Discards parameter changes, exits the current menu, and returns to the previous menu.

Menu Path

After entering the menu via the keys, basic setup can be completed according to the hierarchical path. The figure below shows the menu structure of the E+H radar level transmitter FMR50 series, making it easy to quickly locate the required parameters.
