Flow testing system for fluid networks

摘要

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.

1. A method of testing fluid flow in a network of fluid carrying pipes, comprising:
providing a flow unit and a pressure unit, the flow unit and the pressure unit being units separately moveable with respect to each other; interfacing the pressure unit to a test hydrant; interfacing the flow unit to a flow hydrant; measuring a static pressure of the fluid at the test hydrant by the pressure unit; initiating a flow of water through the flow hydrant; measuring a pitot pressure in the flow from the flow hydrant; measuring a residual pressure in the test hydrant simultaneously with measuring the pitot pressure; transmitting, by a transmitter at the pressure unit, the residual pressure measurement to a receiver at the flow unit; and recording the pitot pressure measurement and the residual pressure measurement on a data storage medium at the flow unit.
