Abstract:
1. A hydrant testing system which measures hydrant pressures at at least two hydrants and determines fluid flow at at least one hydrant, the system comprising: a pressure unit configured to interface with a test hydrant and configured to measure static pressure and then residual pressure of the test hydrant; a flow unit configured to interface with a flow hydrant and to determine a fluid flow at the flow hydrant, the pressure unit and flow unit configured to measure residual pressure and determine the fluid flow at the flow hydrant at about the same time; a transmitter in at least one of the units, the transmitter configured for wireless communication and effective for wirelessly communicating data representative of measurements taken in the at least one of the units; a receiver in at least one of the units, the receiver configured for receipt of wireless communications and effective for receiving data in the wireless communication representative of measurements taken in the other unit and then communicated to the receiver; and at least one data storage device, the system effective for wirelessly communicating data representative of the measurements made at at least one of the units and receiving the communication at the other unit and storing data representative of the measurement of data by both units, the system being configured to measure, transmit and record data representative of the static pressure and residual pressure, and at least measure and record data representative of residual pressure and fluid flow at about the same time.
