摘要
A non interrupting on-line water distribution pressure monitoring system for a dry barrel fire hydrant includes an upper portion or the head and a lower portion or the barrel having an opening. A water flow control mechanism mounted at the opening of the lower portion of the barrel for controlling the water flowing through the barrel. An operating rod for activating the water flow control mechanism having an upper operating rod and a lower operating rod extends through the barrel between the upper and lower portions. The upper operating rod is secured to the head and the bottom of the lower operating rod is secured through the water flow control mechanism to extend beyond the lower portion of the barrel. A water pressure measuring device is housed within the bottom of the lower operating rod and extending beyond the bottom of the lower operating rod. A communication mechanism is positioned remotely from the dry barrel fire hydrant for receipt, collection and distribution of information collected from the water pressure measuring device.
