RENT YOUR FLOWMETERS EASILY ONLINE

Flowmeters will measure flows. Non invasive or « Clamp-On » ultrasonic flowmeters measure flow from the outside of a pipe: you don’t have to empty the pipe or make any change of the pipe to measure the amount of water, compressed air or natural gas that flows through it. You take no risk of contamination or leak. Clamp-On flowmeters for liquids have been in use for many years. Yet two very different kinds of Clam-On flowmeters are used on liquids: some measure a transit time difference and are used on clear liquids charged with few or small particles and bubbles. The other kind of flowmeters uses the Doppler Effect and will analyze the signal reflected by particles or bubbles in the liquid.

On gases such as compressed air or natural gas, the first Clamp-On flowmeters were issued in 2001 by Panametrics (today GE INDUSTRIAL SENSING). They used “Shear Wave” sensor, though users don’t really have to know about that. Other sensors using “Lamb Wave” sensor have been issued by CONTROLOTRON and, more recently in 2008 by FLEXIM. Even the FLEXIM Lamb Wave sensors, which we retain as the best on compressed air, do not measure on certain pipes. For example, it is impossible to measure on a stainless steel pipe DN200 will only 2 mm wall thickness, though it will be possible to measure on a DN200 with a bigger wall thickness. Sometimes, it may happen that the GE SENSING sensors will measure on applications not measured by FLEXIM.

Based in France, Airprofil has become one of the most active French companies in the domain of non invasive ultrasonic flow measurements. Such flow measurements are used for “sizing” or “energy auditing” of compressed air, cooling water and water, nitrogen or natural gas nets. Airprofil now offers excellent flowmeters for rent on the Internet. According to your application, we will try to select the flowmeter which will perform best. It may be a GE SENSING flowmeter, a SIEMENS flowmeter or a FLEXIM flowmeter. If you produce new and better flowmeters, please let us know!

Airprofil will offer a rental service which we would like the most complete as possible:

• Independence from the flowmeters manufacturer: we will always try to find the best flowmeter for your application while manufacturers will always sell or rent their own production.
  

• On site training and checking of the rented meters: you are offered to measure during one day with one Airprofil Engineer. If he cannot measure for any reason – maybe deposits inside the pipe, too much corrosion, insufficient length available – then you don’t have to pay anything and you have not lost too many hours trying to use a flowmeter that was not fit for your application! You can even rent a measurement Engineer together with the flowmeters in order to help you with your measurement campaign.
  

• Most recent updates: one advantage of renting a flowmeter rather than buying it is that you will usually get a recent version of the sensors and the software. We bought three FLEXIM flowmeters type FLUXUS G601 in March 2009. Less than 6 months later, we already got 2 significant updates.
  

• Wide variety of measurements: We try to offer a complete set of sensors for a compressed air station energy audit, a cooling station energy audit or a boiler energy audit. For example: flow(s) + pressure(s) + dew point(s) + electrical power(s). You can reserve and rent all necessary auxiliary sensors, such as hygrometers, temperature or pressure sensors, power analysers, data recorders and not simply flowmeters.
  

• Easy reservation on the Internet the same way you reserve a room in a hotel!
