A metering device regulates the refrigerant liquid to flow at the proper rate.
He held a tool box in one hand and a jumble of wiring attached to a metering device in the other.
This equipment is used in larger pipelines where automatic metering devices would not be sufficiently reliable.
The necessary protection and metering devices are included for the high voltage leads.
A utility meter is any of the following metering devices used on utility mains:
