Temperature Range
Measurement Accuracy
-40°F to +32°F (-40°C to 0°C)
+/- 0.4°F (+/- 0.2°C)
32°F to 140°F (0°C to 60°C)
+/- 0.5°F (+/- 0.3°C)
You can configure the units of measure (°F or °C) and the reference base temperature by using the
Dresser MeterWare software.
For ease of calibration, you can use the Dresser MeterWare software to perform a single point
temperature field calibration.

Flow Rate Measurement
Access the flow rate by scrolling to the Flow Rate screen (
FLOWRATE
) on the meter’s LCD screen
, as
described in Section 4.1. The flow rate indication is not instantaneous, but it is based on the average flow
rate of the last thirty (30) seconds of the saved uncorrected volume data.
Because the meter updates and stores the data collected every thirty (30) seconds, there is a slight delay
in the timing of the displayed results ranging from 1 to 29 seconds until the results are updated again.
