A sensor assembly includes a sensor unit including a generally rigid sensor housing and at least one electronic sensor component, a conduit coupled with the sensor unit and extending away from the sensor housing, and a rigid support structure supporting a portion of at least one of the conduit or the sensor housing at a first end adjacent the sensor unit and extending away from the sensor unit to a length of at least about 6 feet. The rigid support structure configured to maintain the sensor unit within an internal structure for monitoring using the electronic sensor component.

A mobile fire hydrant (MFH) has a substantially planar rectangular base of tubing elements, with an inlet that connects to an ascending portion which has an outlet, generally configured as a fire hydrant outlet. Water or other fire abatement fluid, is pumped from a source to the MFH inlet, which then exits from the outlet in a manner very similar to that of a permanent fire hydrant. A switch mounted on the MFH controls the pump remotely through a pump cable as needed, allowing remote access to water sources at locations beyond 300 feet in distance and 75 in height, depending on pump specifications. This allows ease of water supply for firefighting in remote steep areas with streams or lakes otherwise inaccessible to firefighting equipment.

A water and electrical supply system for firefighting may provide both a supply of water and electrical power that are usable by a load device(s), such as an electric pumping system or a battery charging system of a firefighting vehicle such as a fire engine. An electrical connector may be mounted in a connector housing, which may be supported by a hydrant. The electrical connector may be de-energized in a default non-use state.

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 bearing system includes a first bearing, the first bearing being annular in shape and defining a ring aperture, the first bearing including a first surface and a second surface, a second bearing being substantially the same in construction to the first bearing, a first surface of the second bearing contacting a second surface of the first bearing, wherein each of the bearings is constructed of nylon MDS.

A sensing device for a hydrant can include a sensor located entirely within an interior cavity of a hydrant body of the hydrant and configured to measure a property of a fluid of a fluid distribution system and an antenna in communication with the sensor and positioned within the interior cavity.
