 RegFlo™
RF100
The
RegFlo™ RF100 measurement instrument calculates the travel of the
valve plug and, along with inlet and outlet pressure, estimates a
flow based on an algorithm for the regulator type, size and
construction. Currently, the RegFlo™ instrument fits the
2-inch and 4-inch EZR regulators with future plans to include all
sizes of EZR and1098-EGR regulators.
A third pressure sensor is available as an option to measure an
additional auxiliary pressure. An algorithm estimates the flow
through the regulator and archives pressure, travel, and flow data
in history. It also records other parameters such as battery
voltage, minimums and maximum values, etc. Alarms may be
configured to signal abnormal or emergency conditions.

 RegFlo™ RF110
The
RegFlo™ RF110 pressure recorder instrument is used as a standalone
pressure recorder. It is mounted remotely from the regulator.
Pressures are piped to the unit and are measured and archived in
history. The RF110 does not measure travel or estimate flow. Up to 3
pressure sensors may be installed. Other parameters such as battery
output, and minimum and maximum values are also stored. Alarms may
be configured to signal abnormal or emergency conditions.
Flexible and versatile, the RegFlo™ 110 pressure recorder
instrument makes data available for a variety of uses, such as gas
load forecasting, system balancing and modeling, estimating pipeline
inventory, documenting unused system capacity, or to check metering.
NOTE: It is a U.S. Department of Transportation requirement to
document pressure at certain district stations.
