Mains Insertion Mag Testing

Mains Insertion Mag Testing

Ultrasonic flowmeters were introduced by Tokyo Keiki in Japan in 1963, as a far more cost effective solution for measuring flow. We have been working with ultrasonic flowmeters and mains insertion mag testing for over 15 years and guarantee them because we know they work.


Although the technology has not had the strongest reputation in the past, we have a mission to change that perception. Our director, Alan, has sourced the best gear and established a long relationship with the team at Flexim who are leaders in their field. Their equipment is made in their factories in Germany, where Alan was visiting only last week.


Although the technology has been around for over 50 years, we continually find that people are in the dark about it’s full use, reliability and how cost effective it is. The technology is a non-invasive way of measuring flow in a wide variety of pipe sizes, shapes and materials.


The portable options mean flow can be measured in multiple locations on the one site with the one unit and it is light and easy to travel with.


Alan is constantly travelling to different sites around Australia to install and demonstrate the technology and one of the most rewarding parts of this job is seeing the surprise on people’s faces when they see just how good this technology is.


The unit can be setup and running within an hour. With clear access to a site, it is possible to start measuring flow rates immediately.





Ultrasonic Flow Meters

are widely used on both hydrocarbon liquids and on water, and they perform well on both. Multipath ultrasonic flowmeters, meaning those with three or more paths, are used to measure the custody transfer of hydrocarbon liquids.


  • By far, the best reason to use an ultrasonic flow meter of any kind is the lower costs associated with installation. Your system would not need to be shut down and your piping would not need to be altered.
  • Device will not obstruct flow or contaminate processes
  • Lack of moving parts means less maintenance
  • Flow range typically 100:1
  • Can be used with corrosive fluids
  • Mains insertion mag testing
  • Zero pressure drop (Magnetic flow meters also provide no pressure drop if you are installing a meter the same size as the line size)
  • Operates on pipe diameters from 1/2” to 200” (may require 2 or 3 different sets of transducer depending on pipe size and range transducers cover)
  • Insensitive to changes in temperature, viscosity, density or pressure (Temperature will effect the transit time sensor selection requiring high temp sensors above 250F.)
  • Available in a wide variety of communication protocols (Transit Time)
  • Ability to register locally, remotely or to interface with an energy management system (Transit Time)


We would love to work with you

We offer round the clock support as well as years of experience and knowledge. We also provide flow meter hire and rent to buy options, if you would prefer to test the unit first. So whether you need a gas flowmeter, or water flowmeter, find out more about how we can help you measure your application by calling the team who know flow at Flowservices.
