Abstract

A wireless health monitoring system has been developed for determining the height of water condensation in steam pipes. The data acquisition in this system is done remotely using a wireless network system. The developed system is designed to operate in the harsh manhole environment and the pipe temperature of over 200 °C. The test method is an ultrasonic pulse-echo and the hardware that includes a pulser, receiver, a data processor and wireless modem for communication. Data acquisition and signal processing software were developed to determine the water height using adaptive signal processing and data communication that can be controlled while the hardware is installed in a manhole. A statistical decision-making tool is being developed based on the field test data to determine the height of the condensed water height under high noise conditions and other environmental factors.
