  <dc:description>A vibration sensor that monitors the running time of pumps to determine water withdrawal by various public-supply, agricultural, and industrial groups has been developed in response to a need demonstrated by data gathering activities of the U.S. Geological Survey 's National Water Use Information Program. This sensor, the R100 digital vibration-time totalizer, attaches to monitored equipment such as a pump, motor, or pipe facility and senses vibration to determine running time. Battery-powered and packaged for field environment, the R100 can be left unattended for up to 1 year. Time is recorded to the nearest 0.01 hour, or 36 seconds. This operating manual for the R100 digital vibration-time totalizer describes the R100 's principal of operation and gives installation guidelines and instructions for battery replacements.
