OMEGA’s FC-21 and FC-22 flow computers are useful
in a variety of flowmeter applications. The FC-21 is
suitable for liquid batching, volumetric batching, and
corrected-volume applications. The FC-22 is designed
for liquid, gas, steam, and heat applications. Both
models can store multiple flow equations.
These versatile instruments are programmable from
the front panel. During setup, the user can assign
inputs and outputs. For example, the isolated analog
output can monitor the volume flow, corrected-volume
flow, mass flow, temperature, pressure, or density.
The RS232 serial port allows for data logging,
transaction printing, or connection to a modem for
remote meter reading.
