NON-CONFIDENTIAL DESCRIPTION
Dry Flow Meter for Gas Measurement
Technology Description
Scientists at the University of California, Davis, have developed a novel and highly efficient precision gas flow meter. Because of its precision and non-manual operation, the apparatus allows control of certain predetermined variables. For example, the gas flow rate can be continuously measured and recorded during a specified time frame. The new meter is capable of:
- Gas collection and venting,
- Gas holding and measurement, and
- Electronic control and recording.
The major limitations of current flow meters suitable for small flow measurement are:
- Contact with fluid causes loss of some gases.
- Flow is measured by an imprecise and labor-demanding manual logging method.
Applications
Possible applications include:
- Bio-reactors
- Medical and pharmaceutical use
- Fermentation industry
- Electronic industry
- University/research laboratories
Advantages
The advantages of this new precision gas flow meter include:
- Measurement of small flow rates with high precision in the range of 0.01 to 10 liters per minute.
- Measurement of soluble as well as insoluble gases.
- Measurement of continuous or discontinuous gas flow.
- Electronic control and data acquisition.
- Programmable control of output gas volume at selected temperatures and pressures.
