Metri IC-FMS Flow Monitor

Metri Measurements made in britain

Designed for use with liquids, the Metri IC-FMS Flow Monitor builds on the success of the LPM.  Featuring rugged radial turbine flow technology with a simple local display transmitter and switch.

The FMS Flow Monitor was designed with ease of use and functionality in mind.  It employs a simple user friendly interface for analog output with configuration for High / Low alarm setpoint at specific flow rates. The FMS is housed in a rugged stainless-steel body and enclosure with toughened glass screen. IP67 rated the display has a 36mm x 28mm backlit LCD screen and 2 x 10 characters of text which provides users with flowrate and totalisation indication. The display also flashes when the alarm set point is exceeded for easy visual alarm / fault indication.

The FMS is ideal for a wide range of general purpose, medical and industrial applications where stainless steel wetted parts are acceptable and  good repeatability accuracy are essential. Designed with simplicity and flexibility in mind this high quality flow sensor can be configured with a variety of connection types, at pressure to 100 Bar and temperature to 350 deg C. Further customisation is possible, consult our engineers for further details on options.
