Smart Fire Hose Flow Monitoring System

NIST Inventors

Gregory W. Vogl and Wai Cheong Tam

This invention introduces a wireless sensor network to measure water flow rate in fire hoses, enhancing firefighting efficiency. It uses piezoelectric accelerometers attached externally to detect vibrations caused by flowing water. These signals are wirelessly transmitted to a base station, where

Wireless Fire Hose Flow Rate Apparatus And Measuring Flow Rate In A Fire Hose

NIST Inventors

Gregory W. Vogl , Wai Cheong Tam and Christopher U Brown

A wireless sensor network was used to measure water-flow rate in a fire hose. An accelerometer was chosen as the sensor to measure the flow rate based on the vibrations generated by water flowing through a fire hose close to the hose nozzle. These sensors are small, lightweight, and can attach to
