Description

The FLMW and FLMH variable area 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. Available scaled for water or oil, in Aluminum, Brass or Stainless Steel bodies.

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.
