2-Wires Flow Monitor & Transmitter – FLS M9.00
The new FLS M9.00 is a powerful flow monitor and transmitter based on 2-wire technology designed to convert the frequency signal of FLS flow sensors into a flow rate. M9.00 is equipped with a wide 4” display which shows measured values clearly. Moreover, the standard backlight improves further the display visibility.
The first procedure will grant an easy set up of main parameters. A flow rate reference can be used for a recalibration or alignment through a intuitive “in-line calibration”.
A 2 wires 4–20mA output combined with a solid state relay allow to remote instant flow rate as well as an alarm. M9.00 is equipped with a USB port which allows easy updating of instrument software by customer.
