摘要： By implementing an oil monitoring in a rotary meter, the meter can check the oil level, condition and/or both level and condition and report any issues detected such as out-of-limit low oil condition, contamination, etc. The function can trigger a preventative maintenance on the rotary gas meter with a view to improving its longevity. Oil level monitoring may be signalled using sensors such as switches. Oil colour, clarity, aeration and foaming, corrosion, varnish, wear debris, or other quality monitoring may be signalled using sensors such as spectrometers. A rotary meter may be configured with one or more such sensors for (multi-)parameter monitoring and the one or more sensors positioned in respective locations such as at an oil reservoir.

摘要： A magnetic sensor assembly for rotary gas meters includes a counter module electronic volume corrector (“EVC”). In one aspect, the assembly includes a magnetic sensor probe configured to be releasably secured within an aperture of a first gas meter body. The sensor probe may alternatively be positioned within an adapter sleeve. The adapter sleeve is configured to be releasably secured within an aperture of a second gas meter body. In another aspect, the counter module EVC includes a base coupling member, and the assembly includes first and second magnetic sensor probes, the probe being configured to be releasably secured within apertures of first and second gas meter bodies, respectively. Each probe has a probe coupling member that is releasably engagable with the base coupling member.

摘要： A gas meter with a rated maximum flow capacity of greater than 3,000 CFH (Cubic Feet per Hour)—for example, between 3,500 CFH and 7,000 CFH—is provided with 2-inch flange connectors. One or more undercuts are provided in the meter body to promote satisfactory performance in terms of, for example, differential pressures at the meter inlet and outlet.

摘要： A direction selective unidirectional clutch assembly for a fluid meter counter module assembly is characterized by a drive selector mechanism to couple a direction selection drive shaft to a unidirectional clutch to select one of a first flow direction and a second flow direction of flow of the fluid to drive a counter module. The direction selection draft is coupled to a rotating member (e.g. impeller) driven by flow of the fluid and rotates in a direction that is responsive to the direction of rotation of the rotating member. A pair of gears are mounted to slide along the direction selection draft between a first position and a second position. A direction changing gear is mounted at the second position. Further provided is a flow meter with a direction selective unidirectional clutch assembly.

摘要： An apparatus for use with a backup counter module, the apparatus having: a housing having a first end for coupling the housing to a gas meter body, and a second end for coupling an electronic counter module to the housing; and the second end having an inner surface with at least two sets of backup counter module engagement features for securing an output end of a backup counter module in one of at least two backup counter module positions. The housing may be coupled to a first gas meter body with a backup counter module positioned within the housing in one of the at least two backup counter module positions. The housing may alternatively be coupled to a second gas meter body with the backup counter module positioned within the housing in another of the at least two backup counter module positions.
