Wet barrel hydrant with pressure monitoring and leak detection

A pressure monitoring and leak detection system for a wet barrel hydrant comprising:

• a pressure monitoring subsystem comprising a threaded connector configured to externally mount the pressure monitoring subsystem to the wet barrel hydrant and comprising;
• a pressure sensor configured to measure the pressure of a fluid received in a barrel of the wet barrel hydrant;
• a first processor configured to process pressure data measured by the pressure sensor;
• and
• a first antenna configured to send a pressure signal representative of the pressure data processed by the first processor to a remote location;
• and
• a leak detection subsystem comprising;
• a vibration sensor configured to measure vibrations in a pipeline system connected to the wet barrel hydrant;
• a second processor configured to process vibration data measured by the vibration sensor;
• and
• a second antenna configured to send a leak signal representative of the vibration data processed by the second processor to the remote location, the second antenna in communication with the first antenna.

A method for using a pressure monitoring and leak detection system comprising:

• measuring the water pressure of water received in a hydrant cavity of a wet barrel hydrant with a pressure sensor of a pressure monitoring subsystem, the pressure monitoring subsystem mounted to the wet barrel hydrant;
• processing the water pressure data to determine whether an anomaly is present;
• automatically triggering a leak detection subsystem to run a leak detection cycle when an anomaly is determined to be present to determine whether a possible leak is present, the leak detection subsystem mounted to the wet barrel hydrant and comprising a vibration sensor;
• and
• sending an alert signal to a remote location when a possible leak is determined to be present.
