A hydrant apparatus may be employed to monitor a water distribution system, and may include a sensor, a processor, and a local clock source. The apparatus may wake from a low power mode to a sensing mode, receive the sensor data, associate the sensor data with a first local clock time, and return the apparatus to the low power mode from the sensing mode. The apparatus may subsequently wake to an operational mode, determine a second local clock time subsequent to the first local clock time, associate an external clock time with the second local clock time, determine an offset for the received sensor data based on the first local clock time and the association between the second local clock time and the external clock time, and transmit the sensor data and the offset to an external monitoring system.

Apparatuses for a hydrant, as well as associated methods for installing the same, may be directed to a threaded stem for actuating a hydrant outlet valve at a first end of the stem. An attachment nut may define a bore for supporting the stem in the hydrant. The attachment nut defines a cavity configured to receive water from a barrel of the hydrant. The attachment nut also defines a water access passage extending through an outer wall of the attachment nut to the cavity. The apparatus also includes a sensor in fluid communication with the cavity to obtain sensor data for the water in the barrel.
A liquid monitoring system includes a remote measurement device located at a location of the fire hydrant that is in contact with water provided by a water main. The remote measurement device has sensors that measure characteristics of the water and/or acoustic vibrations in the water and a communication interface that transmits measured information to a communication network device that may be located elsewhere on the fire hydrant. The communication network device communicates with a communication network.

A communications and control system for use with a utility meter includes a first wireless communications subsystem for exchanging messages with a central facility via a cellular communications network. The first wireless communications system is operable to send messages including meter data generated by the utility meter to the central facility and receive utility control messages from the central facility for controlling the provision of a utility monitored by the utility meter. A second wireless subsystem communicates within a wireless mesh network of compatible wireless subsystems operating in conjunction with a set of utility meters for exchanging the meter data with a selected compatible wireless subsystem within the mesh network.
