ProSense® Variable Area Flow Meters

ProSense FG1 Series mechanical variable area flow meters provide visual indication of flow rate for water or petroleum based fluids. These meters provide +/-5% full scale accuracy when monitoring liquids with viscosity and specific gravity similar to the factory calibrated fluids and a repeatability of +/-1% that is important for cyclical applications requiring consistent readings. Two adjustable flow limit pointers are available to provide preset visual indication of high, low, or normal flow rates.

• Constructed of high-impact polysulfone plastic, these flow meters are available with 1/2", 3/4" or 1" NPT process connections and several easy to read flow scales in both gallons per minute (GPM) and liters per minute (LPM).
• The unique spring loaded variable area design allows the FG1 series flow meters to be installed in-line in any position without affecting accuracy and makes them relatively insensitive to shock and vibration.
• No special plumbing or accessories are required to stabilize turbulent flow because the FG1 series meters can be installed immediately adjacent to 90-degree elbows or other piping components allowing for system design flexibility.
