Illustrative embodiments of a meter box and couplings, either separately or in combination, are provided. An illustrative embodiment provides a valve coupling that is disposed through a wall of the meter box such that a first portion of the valve coupling extends exterior of the meter box and a second portion of the valve coupling extends interior of the meter box. An outlet coupling is disposed through the wall of the meter box such that a first portion of the outlet coupling extends exterior of the meter box and a second portion of the outlet coupling extends interior of the meter box. A telescoping tube is located in the meter box, extended into and movable relative to, and in fluid communication with, at least one of the second portion of the valve coupling and/or the second portion of the outlet coupling. The telescoping tube varies a distance between the valve coupling and the outlet coupling within the meter box.

A system includes a flow sensor contained within a flow sensor housing, a base, and a seal. The base houses a controller that generates at least one operation modification signal, and the flow sensor is separable from and mountable onto the base. A bottom surface of the flow sensor housing includes the seal. The seal forms a liquid-tight engagement between the flow sensor housing and the base when the flow sensor is mounted onto the base.

The design and structure of a fluidic concentration metering device with a full dynamic range utilizing micro-machined thermal time-of-flight sensing elements is exhibited in this disclosure. With an additional identical sensing chip but packaged at the different locations in the measurement fluidic chamber with a closed conduit, the device can simultaneously measure the fluidic concentration and the fluidic flowrate. With a temperature thermistor integrated on the same micro-machined thermal sensing chip, the disclosed device will be able to provide the key processing parameters for the fluidic applications.
