When in programming mode, the left-most alphanumeric character blinks. Use the UP or DN keys to
increase or decrease the value. Use the SEL key to move to the next selection. When you have achieved
the desired value, press ENT to store. See Programming the FEM-03 beginning on Page 21 for complete
details.
Product Description
The FEM-03 Flow Monitor is a versatile, multi-functional device that helps you track rate, flow, limit,
ratio, and other variables. The unit’s large, back-lighted LCD display is easy-to-read with up to 22
different display modes available, depending on model. The standard unit is one channel, but the
optional two-channel version allows you to monitor dual flows and display them in a number of ways:
separately, as a sum (for example in total material use), as a difference (as in fuel consumption), or as a
ratio of product A/product B. You can also use the FEM-03 to detect bi-directional flow when A and B
channel signals are available from a single flow meter.
Other capabilities include the capacity to monitor data and program the unit remotely. Four model
variations give the FEM-03 the capability of performing limit, warning and alarm duties.
Principle of Operation
After first making connections to the power source and to flow transmitter input and output, you can
choose up to 22 display modes. These include rates, totals, ratios, limits, printer status, and others,
based on the model purchased. Then input k- and t-factor values, the required engineering units,
sampling rates, gate times, limits, etc. You may also program other values such as warning/alarm limits
and ratios, depending on model.
