Abstract
An automatic fire hydrant water supplying system provides hydrant supply water to a fire truck having a water pump; a water pump master intake valve; a water-supply fire hose, a pressure sensor upstream of the master-intake-valve, and a water-pump control system. The automatic fire hydrant water supplying system has a remotely-controllable hydrant discharge valve connectable to the hydrant and to the fire-hose. A remotely-controllable air bleed valve is in fluid communication with the master-intake-valve and the fire-hose. The water-pump control system determines whether a pressurized volume in the fire hose upstream of the master-intake-valve input port is air or water based on a difference in density between air and water as sensed by the pressure sensor and if the pressurized volume is air causes the air to be vented to atmosphere through the air-bleed-valve before opening the master-intake-valve to provide hydrant supply water to the water pump.
