RegFlo Pressure and Flow Instruments

RegFlo RF100 Series Pressure and Flow Instruments

RegFlo RF100 Series pressure and flow instruments are devices which measure and archive flow and pressure data. Other parameters such as battery voltage, and minimum and maximum values are also stored. Alarms may be configured to signal abnormal or emergency conditions. The Type RF110 instrument is used as a standalone pressure instrument. Mounted on a regulator, such as the Type EZR, the Type RF100 instrument measures pressure and also estimates flow rates based on valve plug travel.

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)
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
