The FLMW and FLMH flowmeters can be installed directly in the fluid line without flow straighteners or special piping. The spring-and-piston type assembly enables these flowmeters to be mounted in any position and protects them against changes in viscosity.
The FLMW or the FMLH Series with the optional analog output (-MA) are typically used to transmit a signal proportional to the flow rate to a process controller, a PLC, a recorder, or a panel-mount display. With the -MA options the user can choose between reading a 0 to 2000 Hz square-wave pulse, a 0 to 5 Vdc analog signal, or a 2-wire 4 to 20 mA analog signal by connecting the appropriate pins.
