The new FLS M9.00 is a powerful flow indicator and transmitter based on 2-wire technology, designed to convert the frequency signal of FLS flow sensors into flow rate.

The M9.00 indicator is equipped with a large 4" display which displays the measured values extremely clearly. Furthermore, the standard backlighting further improves the visibility of the display.

The main parameters can be configured with a first wizard.

A reference range can be used for recalibration or for an alignment through an intuitive "inline calibration".

A 2-wire 4-20 mA analog signal combined with a solid state relay allows remote management of the instantaneous flow rate or an alarm.

The M9.00 indicator is equipped with a USB port which facilitates the updating of the instrument software by the customer.
