The portable flow meter UDM 100 is used for precise measurement of direction of flow and actual flow volume of potable water in water supply networks ultrasonically. This measurement is made on the outer surface of the pipe. Flow measurements of this kind must be taken, for instance, when designing pumping power or when determining zero consumption in the analysis of leakage. The flow velocity of liquid media can be measured, too, e. g. to avoid the sediments in a pipe from coming off or to ensure minimum flow velocity in a potable water system in order to maintain high quality. Temperature or heat values can be measured by means of one or two PT 100 sensors. The Ultrasonic Flow Measuring Device employs the principle of measuring the difference of travel times between two ultrasonic sensors. Depending on pipe diameter, two sensors are attached either side by side (reflection measurement) or on opposite sides (flow measurement). These intelligent sensors make re-calibration unnecessary when sites are changed, as their own calibration data are stored. Measuring time can be programmed at will, unattended measurements without the presence of an operator can be taken, e. g. at night. German, English and French are available as user languages.
