Abstract: A high frequency data recorder (“HFDR”) can include a first set of contacts, on a first side of the HFDR, that are pluggable into a first meter receptacle of a meter box, wherein the first meter receptacle provides a connection to a power supply and a connection to a load. The HFDR also includes a second set of contacts, on a second side of the HFDR, that form a second meter receptacle. The second meter receptacle provides another connection to the power supply and another connection to the load. The HFDR can further include a processor that accesses a non-transitory machine readable memory that stores instruction that when executed cause the processor to passively measures current downstream from the meter box. The HFDR still further includes a wireless transceiver that wirelessly transmits data characterizing the measured current.

Abstract: An apparatus for reducing the outlet bore restriction of the inlet tube of existing outage gauges from a diameter of 0.055 in. to a chosen diameter, thereby reducing the quantity of LP Liquid and/or Gas, or other liquid or gaseous fluid, escaping from an LP Gas tank during filling thereof, is described. By retrofitting the original valve stem of an outage gauge with an adapter having a smaller inlet bore and a smaller stem, which screws into the adapter, the restriction of the outlet bore is achieved without requiring the emptying the LP Gas tank upon which the outage gauge is mounted.
