FLS M9.02 is a highly efficient flow indicator and is designed to convert the frequency signal of FLS flow sensors into flow rate.

The M9.02 indicator is equipped with a large 4” graphic display which clearly shows the measured values and many other useful information.

The color display and powerful backlighting make it easy to determine the measurement status even from a distance. The software provides assistance to minimize errors and speed up the configuration of all parameters to the maximum.

Calibration can be done by tweaking the setup features or using a reference value with the new “Online Calibration”.

A 4-20mA output is available to communicate flow rate to an external remote device. A suitable combination of digital outputs allows you to customize the configuration to control any process.

The USB port on the rear allows you to update the software with a wide range of standard and optional customization services.
