摘要： Example aspects of a pressure monitoring system for a wet barrel hydrant, a pressure monitoring and leak detection system for a wet barrel hydrant, and a method for using a pressure monitoring and leak detection system are disclosed. The pressure monitoring system for a wet barrel hydrant can comprise a pressure sensor assembly comprising a pressure sensor and a connector, the pressure sensor configured to measure the pressure of a fluid received in the wet barrel hydrant, the connector configured to attach the pressure monitoring system to the wet barrel hydrant; a mounting flange coupled to the pressure sensor assembly; a main PCB configured to process pressure data measured by the pressure sensor; an antenna configured to send a signal representative of the pressure data; and a housing coupled to the mounting flange, the housing enclosing the processor and the antenna.
