Abstract
A flow testing system comprises a flow unit for interfacing with a flow hydrant, a pressure unit for interfacing with a test hydrant, a transmitter in a first one of the units to transmit data to a second one of the units, a receiver in the second unit to receive data from the transmitter, and a data storage medium in the second unit to record data. A method includes providing flow and pressure units, interfacing the pressure unit to a test hydrant and the flow unit to a flow hydrant, measuring static pressure by the pressure unit, initiating water flow through the flow hydrant, measuring pitot pressure in the flow, measuring residual pressure in the test hydrant, transmitting the residual pressure measurement from the pressure to the flow unit, and recording the pitot and residual pressure measurements.
