  • Meter devices and methods
    Patent number: 8166830
    Abstract: Some embodiments of a meter device for measuring volume flow of gas can include bearings and the timing gears may each include a least one component comprising a ceramic material that enhances the wearability of the bearing and the timing gears. Accordingly, the gas flow meter can operate in a manner that reduces or eliminates the need for external oil lubrication of the bearings and the timing gears (e.g., the external oil lubrication conventionally provided by the oil bath compartment), and thus reduces the likelihood of failure of the gas flow meter due to leaks or failures of the oil bath compartment.
    Type: Grant
    Filed: July 2, 2010
    Date of Patent: May 1, 2012
