What is a FEM-03 Flow Monitor?
The FEM-03 is available as a simple, compact easy to use flow monitor. A large, backlighted
LCD graphic display provides easy to read indication of flow rate, totals or ratios. Two Form C
relay outputs can be programmed to perform limit, warning or alarm functions. Remote programming or monitoring is available via the RS-232 serial communications port. The FEM03A model has a 4-20mA output to track data remotely. The FEM-03A2 model is equipped
with 2 channels to monitor dual flows and display them separately or as a sum (as in total
material use) or as a difference (as in fuel consumption) or as a ratio of A/B. This unit can
also be configured to monitor and detect bi-directional flow when “A” and “B” channel (90°
phase shifted) signals are available from a single flow meter.
