RegFlo RF100 Series Pressure and Flow Instruments

RegFlo RF100 Series pressure and flow instruments are devices which measure and archive flow and pressure data. The Type RF110 instrument is used as a standalone pressure recorder. The Type RF100 instrument is mounted on a regulator, such as a Type EZR and can also estimate flow rates as well as record valve plug travel. Other parameters such as minimum and maximum values are also stored. Alarms may be configured to signal abnormal or emergency conditions.

RF100 Flow Recorder
The RegFlo Type RF100 instrument measures valve plug travel, inlet pressure, and outlet pressure. 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.

RF110 Electronic Pressure Recorder (EPR)
RegFlo Type RF110 Instrument
The RegFlo Type RF110 Instrument is used as a standalone pressure recorder. It is the same as the Type RF100 except it is mounted remotely from the regulator and does not measure regulator travel or estimate flow rates. Pressures are piped to the unit and are measured and archived in history. 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.
