The TFX-5000 transit time ultrasonic flow 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 raw sewage.

TFX-5000 flow meter clamps onto the outside of pipes and do not contact the internal liquid.


The TFX-5000 meter is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.
The TFX-5000 meter is suitable for:

- Water Delivery
- Sewage
- Cooling Water
- Water-glycol mixtures
- Alcohols
- Chemicals


Transit time flow meters measure the time difference between the travel time of an ultrasound wave going with the fluid flow and against the fluid flow. The time difference is used to calculate the velocity of the fluid traveling in a closed-pipe system. The transducers used in transit time measurements operate alternately as transmitters and receivers. Transit time measurements are bi-directional and are most effective for fluids that have low concentrations of suspended solids and are sonically conductive.

Does this meter have a straight line pipe requirement?

Asked by: MDugan
Thank you for your inquiry. Yes, typically a straight run of 10x the pipe diameter upstream and 5x the pipe diameter downstream will be sufficient.
