FLS M9.20 is a smart battery operated flow indicator designed to convert the frequency signal of FLS sensors into flow rate.

The M9.20 indicator is equipped with a long-lasting lithium battery which also powers the sensors.

The large 4" display shows the measured values very clearly. The main parameters can be configured with an initial guided procedure.

For a calibration or alignment using an extremely intuitive online calibration procedure, a reference flow can be used.

A safety icon alerts you when it's time to replace the battery and the instrument automatically stores all main parameters.

A customizable string allows you to easily display the display level.

The M9.20 indicator is equipped with a USB port which facilitates software updating by the end user.
