MC-III™ EXP Flow Analyzer Section 1
Section 1—Introduction
The NuFlo™ MC-III™ EXP Flow Analyzer (Figure 1.1) packs a full spectrum of gas and liquid measurement
functionality, high-speed performance, and log archive and retrieval capabilities in an easy-to-use, explosion-
proof totalizer. Commonly used operations can be accessed from the six-button keypad on the front of the
instrument or from the dynamic interface software, allowing you to calibrate and congure the unit quickly
and easily.
When the MC-III EXP is installed in accordance with the provisions in this manual (Section 2, page 19), it is
approved by CSA for use in hazardous areas in Canada and the United States, and meets the ATEX/IECEx
standards for use in hazardous areas worldwide.
Operation
The MC-III EXP calculates and displays instantaneous ow rates and accumulated totals based on a turbine
owmeter input signal. The MC-III’s microprocessor circuitry counts the pulses generated by a companion
owmeter, converts that data into volume and rate values in accordance with calibration settings, and displays
the totalized data on a two-line liquid crystal display (LCD). The eight-digit top readout indicates total ow
volume; the six-digit bottom readout indicates ow rate.
