MC-III
TM
WP Flow Analyzer offers state-of-the art liquid and gas measurement
with data logging and Modbus
®
communications in an easy-to-use weatherproof totalizer.
With the capacity to record up to 384 daily flow logs, 768 hourly logs, and 345 event logs,
the MC-III WP is a powerful addition to any flow measurement operation.
Features
The MC-III WP offers:
RS-485 Modbus communications
Extensive log archival capacity
High-speed downloads (less than
a minute, based on 115 K baud)
Easy-to-read LCD displays
12-point linearization
Simultaneous indication of rate
and total
Loop-powered analog output
Nonvolatile memory
Password-protected security options
Direct or remote mount
Modbus communication,
logging and accurate
flow measurement –
all in one compact
weatherproof device
Each unit is supplied with
one conduit hub for I/O
access; two seals can be
replaced with additional
hubs (as shown).
Calibration
Calibrating the MC-III WP
for liquid measurement is as
easy as entering the calibration factor of
the flow meter and selecting the desired
units of measurement. The instrument
automatically calculates its own divisor.
When the instrument is paired with a
gas flow meter, the user enters the
calibration factor of the meter, pressure
and temperature parameters and FPV via
the MC-III interface software. The wide
variety of unit options for total and rate
gives users the freedom to customize
the display, inputs and outputs for
specific needs.

Keypad Configuration
The MC-III WP is easily configured with the six-button keypad on the front of the
instrument. Built-in shortcuts to common functions (see figure below) reduce the user’s
time spent on-site.
Inputs/Outputs
The MC-III WP connects to a turbine meter or
a pre-amplifier. Users can select a 4 to 20 mA
output, a pulse output, or an amplified flow
meter frequency output that allows remote
equipment to calculate flow rates and volume.
