MC-II Flow Analyzer
1
Introduction
The NuFlo MC-II Flow Analyzer combines with a turbine flowmeter to provide an accurate display of accu-
mulated flow volume and flow rate of liquids and gases in a simple-to-use, battery-powered instrument. The
MC-II’s microprocessor circuitry counts the pulses generated by a companion flowmeter, converts that data
into volume and rate values in accordance with calibration settings, and displays the totalized data on two
six-digit liquid crystal displays (LCD’s). The top LCD indicates total flow volume; the bottom LCD indicates
flow rate.
The flow rate decimal point position is determined auto-
matically by the MC-II, as dictated by flow conditions. As
the flow rate changes, the flow rate decimal point will shift
position to provide maximum resolution.
The MC-II has no internal potentiometers, jumpers, or dip
switches to adjust. For applications that rely on standard
engineering units, the MC-II automatically calculates the
divisor when you supply the calibration factor of the com-
panion flowmeter.
With the simplistic MC-II design, you can save totals in
nonvolatile memory with the press of a button on the key-
pad, or reset the total display (to zero or to a predetermined
value).
A password-protection security feature deters unauthor-
ized personnel from altering the calibration or accumulated
volume data in the instrument. The security function may
be enabled or disabled, using the keypad.
The low current draw of the MC-II’s CMOS circuitry enables the MC-II to run for 3 to 5 years on a single
3.6V lithium battery. This durable power supply and the MC-II’s noncorrosive weatherproof enclosure make
it ideal for use in remote locations.
In addition, the MC-II can be purchased with a pulse-output option that provides a scaled pulse output rep-
resenting an increment in volume for each pulse. The pulse output function can be disabled when not in use,
reducing current consumption. Installation and operation instructions for the pulse output option are provided
in Appendices A and B.
