The disclosed portable self-powered flow measuring device has a non-metallic housing through which a fluid flows. An annular turbine spins within the housing, and has a set of inwardly-extending vanes set to reduce the pressure of the flowing fluid by more than 10%. A set of magnets that are spaced circumferentially about the turbine. Coils are mounted to the housing with axes that are radial to the axis of the central waterway. A set of circumferentially spaced reinforcing arms, one for each coil, are positioned outside the coils, the circumferential width of each reinforcing arm near the axial position of the turbine being no more than the radius of the coil.

A decoupler tool for decoupling a Storz coupler is disclosed having a base member and handle and decoupling member attached to the base member. The handle and decoupling member may include two handles and each handle includes vertical leg having a protrusion for engaging a coupling lug or coupling lock release member of a Storz coupler.

A device is disclosed that may include a housing configured to snap onto a wand of a fogging machine near the nozzle. In addition, the device may include a positioning ramp fixedly attached to the housing. The device may include a cradle configured to hold a flashlight fixedly attached to the positioning ramp. Moreover, the device may include where the positioning ramp is configured to aim the beam of the flashlight obliquely at the nozzle to illuminate the spray pattern of the air liquid mixture exiting the nozzle. Also, the device is further configured to allow real-time adjustment of the spray pattern and droplet size of the air liquid mixture. Further, the device may include the apparatus being removably attached to the wand such that it may be utilized on various wands.

A fire hydrant assembly for use with an irrigation riser stub may include a generally cylindrically-shaped main body having an open end and a closed end. The open end of the main body has an inside diameter that is sized to slidably receive an end portion of the irrigation riser stub. A seal disposed within the open end of the main body is sized to sealingly engage the irrigation riser stub. A nipple having a threaded end and a plain end is mounted within an opening provided in a side portion of the main body so that the threaded end may be threaded onto a fire hose assembly. An actuator shaft extends through a shaft opening defined by the closed end of the main body so that a head end of the actuator shaft is disposed outside the main body and so that a distal end of the actuator shaft is disposed within an interior cavity defined by the main body. A yoke mounted to the distal end of the actuator shaft is sized to operatively engage a valve stem associated with the irrigation riser stub.

Systems and methods are provided for aircraft fire extinguishing with heated tubing. One example is a fire extinguishing system that includes a container configured to store a fire extinguishing agent, a tube configured to transport the fire extinguishing agent from the container to a compartment of the aircraft, and a valve configured to initiate a discharge of the fire extinguishing agent from the container and through the tube. The fire extinguishing system also includes a heating element thermally coupled with the tube, and a control member in a cockpit of the aircraft configured to direct the heating element to heat the tube prior to initiating the discharge of the fire extinguishing agent via the valve.

A fire hose coupling comprises a body having a first end connected to a fire hose and a second end having either male or female threads or, alternatively, a quarter-turn sexless coupler. The fire hose coupling comprises a recessed portion formed in an outer surface of the body. The recessed portion is shaped to define a visuotactile directional indicator such as an arrow. The recessed portion may include a light-reflecting surface to enhance visibility such as a super reflective metal film, a photo luminescent coating, or a phosfluorescent coating. The recessed directional indicator may be formed in female, male or sexless (Storz) couplings.
