The Bubble-O-Meter products measure the flow of all gases at various temperatures without recalibration over a wide range of flow rates.

They are very simple to use. Time the bubble as it travels between two calibration marks. Use the Flow Calculator or Nomograph to determine the flow rate. Then adjust as necessary for atmospheric pressure & temperature.

Most Bubble-O-Meters have several stages. These stages allow one Bubble-O-Meter to operate over a large range of flow rates. A single Bubble-O-Meter can be the measurement solution for multiple applications. We have engineered several flow meters into one convenient design.
