High Precision Film Flow Meter combines precision volumetric tubes with a soap film detector that allows it to measure the flow of a high number of gases accurately. The Film Flow Meter measures the amount of time required for the movement of soap film through a known portion of the volumetric tubing, and determines the gas flow rate using that time value. The Film Flow Meter measures the atmospheric pressure and temperature thus compensating for these prior to calculating the actual flow. The Film Flow Meter is Suitable for a range of gas flow rates by using one of the four volumetric units. High Precision Film Flow Meter also features an internal atmospheric pressure sensor.
