General information

The TFX-5000 transit time meter measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or sewage.

TFX-5000 ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid.

Measuring principle

Heat meters

Heat meters

The heat meters use the highly precise ultrasonic transit time measuring principle, for which two ultrasonic sensors are externally mounted on the pipeline and connected to the electronic. The ultrasonic sensors work alternately as transmitter and receiver, and mutually send ultrasonic signals. During these transmissions, the respective signal transit times of the to-and-from signals (t1, t2) are measured.  

The electronic measures the difference of the transit time of the ultrasonic signals going with and against the flow direction t1 and t2. These signals are either decelerated or accelerated by the medium flow. The difference produced in both signal transit times is proportional to the flow rate and is used together with the pipeline geometry for a precise flow calculation
