Example: Liquid Measurement with User-Defined Units of
Measure
Calculating the divisor for liquids is necessary when registering the vol-
ume in units other than barrels, gallons, cubic meters, or liters. User-de-
fined (
USEr
) units may be used for the volume total and preprogrammed
units for the flow rate.
Note—Each MC-II is shipped with a label set (Part No. 100080190) con-
taining labels for commonly used flow rate and volume units. The appro-
priate label can be placed on the front panel on the right side of the LCD
viewing window.
Calibration Information
•
A NuFlo ¾-in. turbine meter is being used to measure injected water
for a water flood project.
•
The turbine meter calibration factor is 2977.01 pulses per gallon.
•
The volume is to be measured in kiloliters and displayed to an accu-
racy of one-tenth of a kiloliter.
•
The units of measure for flow rate will be kiloliters per day.
•
No preprogrammed volume is to be entered.
•
The pulse output will not be used.
•
The security code is disabled and the MC-II is in the Run mode.
•
The MC-II has not been calibrated and is at factory default settings.
Step-by-Step Calibration Procedure
1. Calculate the divisor and divisor decimal point position.
a. Determine the factor for converting gallons to kiloliters. Since
there are 264.17 gallons per kiloliter, the conversion factor for
this example is 264.17.
b. Use the following formula to determine the divisor.
Divisor = Meter factor in pulses per gallon × conversion factor
for pulses per unit volume of desired measure
Divisor = 2977.01 × 264.17 = 786,436.73.
c. Round the divisor to six digits (to accommodate the six-digit limit
of the MC-II display). In this example, the divisor to be entered
into the MC-II is 786,437.
2. To begin the calibration process, press and hold ACCESS for 3 sec-
onds, then release, to enter the Calibrate Mode. The MC-II performs
a diagnostic test that momentarily displays all segments of the LCD.
The firmware version is then displayed by showing Prog.no on the
upper display and the firmware version on the lower display.
