Patent ID: 7917324

Claim:
A method which measures pressure at least one test hydrant and determines fluid flow at least one flow hydrant with a pressure unit and a flow unit, respectively, and stores data arising from the measured pressure and fluid flow, the method comprising: interfacing the pressure unit to the test hydrant; interfacing the flow unit to the flow hydrant; initiating a fluid flow through the flow hydrant to start a test event; determining the fluid flow at the flow hydrant as a part of the test event; measuring a residual pressure in the test hydrant substantially simultaneously with determining the fluid flow at the flow hydrant; substantially simultaneously with the test event, wirelessly transmitting a signal from a test transmitter provided at the pressure unit to a flow receiver provided at the fluid flow unit, which signal is representative of data which describes at least one of the residual pressure measurement, and storing data representative of the fluid flow and the residual pressure measurement in a storage medium at least one of the units substantially simultaneously with the test event.
