1. A system for monitoring gas flow and pressure to a gas appliance in a fluid network comprising:
an analyzer configured for temporary installation in-line and upstream of a fluid network, including:
a housing defining an inlet, an outlet, and an interior in fluid communication with the inlet and the outlet; and a first pressure sensor configured to generate a first signal related to a flow of gas being supplied to the gas appliance; and
a device configured to communicate with the analyzer, wherein the device has a user interface and is configured to monitor, store and display data, wherein the device can present the flow of gas and a capacity of the flow of gas to a user based on the first signal,
wherein the analyzer is loaded with performance curves generated using ambient air, the performance curves being a set of differential pressure readings across an expected range of gas flow values.
