Flow Computer Features - Flowmetrics 922-MFC Installation And Operating Instructions Manual

Scaled digital and 4-20 mA analog current outputs, that
represent compensated flow, are standard for use in re-
mote monitoring of flow. Two form C relays provide iso-
lated compensated flow and temperature/pressure alarm
outputs.
There is a single precision voltage reference in the unit
used for all analog measurements. A single multi-turn
potentiometer is provided for factory calibration.
other adjustments are necessary.

1.2 Flow Computer Features

The Flow Computer is designed to provide accurate and
low cost compensated flow measurement for industrial ap-
plications. The instrument can be set up to display volu-
metric, mass, or heat flow, as well as totalized flow, with
an overall accuracy of
application ranges.
Fully programmable from the front keypad, the micropro-
cessor-based Flow Computer provides the operator with
prompts to set up the operating parameters of the instru-
ment.
The Flow Computer offers the following features:
• Front panel 16 key programming keypad
• 2 line by 20 character backlit LCD display
• Compensates gas, steam & liquid flow rates for
temperature and pressure.
• Direct input of 100Ω RTD
• Can display flow and heat flow rates and totals
• 12 bit input resolution for A/D conversion
• Non-volatile RAM memory
• Self diagnostics of instrument
• RS232 communications (optional)
• Supervisory lockout of keypad
• Provides 24 VDC output @ 100mA (AC Models only)
• Flow rate, temperature and pressure alarms
• Real time clock and calendar (not battery backed)
