Our Top 10 Tips For Selecting A Clamp-On Ultrasonic Flow Meter For Liquid

A broad range of factors can influence your choice of clamp-on ultrasonic flow meter such as the type of liquid to be measured, pipe material and pipe size and selecting a suitable model requires an understanding of the different features and options available. 

Here are 10 Top Tips to help you chose the most suited clamp-on ultrasonic flow meter for your liquid flow application.
1. Why choose a clamp-on ultrasonic flow meter?

Flow meters which clamp on to the outside of the pipe offer many advantages over traditional in-line flow meters: easy installation, no moving parts, no pressure loss, no compatibility issues etc.

2. What are the two basic principles?


Time of Flight, ultrasonic pulses are timed as they are transmitted and then received within a pipe. Doppler Shift, where suspended solids and bubbles reflect an ultrasonic beam.

3. Which principle is best for me?
It depends on your application: clean liquids with little air or suspended particles are suitable for Time of Flight, whereas …

Kuwait ‘Clamp on’ to Tackle Water Woes

Image
Kuwait is one of the most water-scarce regions in the world but at the same time has one of the highest per capita water consumption rates at 500 litres per day. In order to monitor this consumption and develop water management strategies, Kuwait’s Ministry of Electricity and Water have begun deploying innovative water meters.

Working together with an environmental measurement company Bell Flow Systems are undertaking a widespread project to supply and install non-invasive water meters on large domestic properties in Kuwait. With inherent advantages over in-line water meter technologies, the Dynasonics TFX Ultra™ ultrasonic clamp-on flow meters were chosen. 


The TFX Ultra™ simply clamps on to the outside of pipes and does not contact the internal liquid, this non-invasive technology means no remedial work needs to be carried out on pipework. Other advantages include zero pressure head loss, no moving parts to maintain and high accuracy. Equipped with Modbus or BACnet communication the …
