TF1100-EC Wall-mounted Transit-Time Ultrasonic Flowmeter

WaterFlow & Velocity Measurement & Monitoring
TF1100-EC Wall-mounted Transit Time Ultrasonic Flowmeter works on the transit-time method. The clamp-on ultrasonic transducers (sensors) are mounted on the external surface of the pipe for non-invasive and non-intrusive flow measurement of liquid and liquefied gasses in fully filled pipe. Three pairs of transducers are sufficient to cover the most common pipe diameter ranges. In addition, its optional thermal energy measurement capability makes it possible to carry out a complete analysis of thermal energy usage in any facility. This flexible and easy to use flow meter is the ideal tool for the support of service and maintenance activities. It can also be used for the control or even for the temporary replacement of permanently installed meters.
