Abstract: A metering arrangement includes a meter housing, a source of energy signals, a source of gas flow signals, a source of temperature signals, and a processing circuit. The meter housing is securedly supported proximal to a facility receiving utility commodities. The processing circuit is disposed within the meter housing, and is operably connected to the source of energy signals, the source of gas flow signals, and the source of temperature signals. The processing circuit is operable to generate electrical energy consumption metering information from the energy signals. The processing circuit is further operable to generate corrected gas consumption information based on the received gas flow signals and the received temperature signals.

Abstract: A vacuum flow measurement device measures the quantity of air flowing into a high-volume evacuator (HVE) vacuum tip commonly found in dental treatment rooms. The device includes a tubular member constructed to mimic internal structural characteristics of a HVE tip. The tubular member includes a valve end coupleable with a HVE valve and an open end. A pressure gauge is connected to the tubular member via a port spaced from the open end of the tubular member. When the vacuum flow measurement device is coupled with the HVE valve, an air flow rate is determined as a function of pressure measured via the pressure gauge.
