Abstract
A fire hydrant water leak and theft detection system is connected to a dry barrel fire hydrant. The detector is connected to the upper barrel portion of the fire hydrant below the nozzle assembly and includes a pair of electrodes. A signal is generated when water in the upper barrel portion closes an electrical circuit between the two electrodes due to the conductivity of the water between the electrodes. The detection system sends a signal to a network system upon detection of water in the barrel portion and relays to remote monitoring locations.
Claims20
A fire hydrant monitoring system for a fire hydrant having a barrel including an open interior, the fire hydrant monitoring system comprising:
- a housing configured for connection to an exterior surface of the barrel and having a sensing chamber inlet in communication with the open interior of the barrel;
- a controller located in the housing;
- and
- at least one electrode connected to the controller and located in the sensing chamber;
- wherein when water enters the sensing chamber, the electrode detects the presence of water and the controller processes a signal.
A detector for monitoring the presence of water in a fire hydrant comprising:
- a housing connected to the fire hydrant by an inlet fitting having a sensing chamber;
- a pair of electrodes, each electrode having a first end and second end, the first ends spaced from each other within the sensing chamber;
- a processing device connected to the pair of electrodes, wherein when the water is located within the sensing chamber between the two electrodes, the processing device processes a signal;
- and
- a communication device connected to the processing device to transmit the signal.
