Catalog excerpts

ULTRASONIC FLOW METERS BY Flow Measurement Systems ULTRASONIC BATTERY POWERED GENERAL INDUSTRIAL METERS The Hoffer Ultrasonic battery powered flow meters of the Transi-Flo II Series are intended for measurement and storage of instantaneous flow rate and total volume passing through the meter. Typical applications include cold or hot water in accordance to OIML R49-1 and other similar liquids in water and heat supply systems and in a wide range of industrial applications. Optionally, the meters can be provided with pressure gauges to monitor the fluid pressure in the piping. The Transi- Flo II meters are noted for high measurement accuracy and long-term stability over a wide range of measured values. No external power is needed; the meters include no moving parts and compared to conventional flow meters, their pressure drops are significantly lower. The associated electronic unit provides for processing of the sensor signal and display of the instantaneous flow rate, total flow and fluid pressure, as well as for archiving of the measured data in specified time intervals in the internal meter data logging unit. The archived data can be retrieved either via communication line for further processing by, for example, a notebook computer. On-line processing of the measured values is also possible using
