TO MEASURE FROM THE OUTSIDE WHAT FLOWS WITHIN.

Clamp-on Whether it concerns liquids* or gases, leak detection or energy flow, in an open sewer or closed pipe, above ground or underground; with a clamp-on ultrasonic measuring instrument you will obtain reliable results quickly and easily.

*for example water, diesel and oil, but also homogeneous mixtures such as water / glycol or water / hydrochloric acid.

The external mounting of the sensors makes this method an interesting alternative to in-line measurement. It is not necessary to open up a tube or pipe to be able to take the measurement. A clamp-on ultrasonic flowmeter can also be combined with a pressure meter, temperature sensor or a wireless GPRS system.

WHEN CLAMP-ON ?

Because of the advantages that clamp-on flow measuring offers (see the right hand side of this page), this technique is used more and more.

  1. For measuring, checking and adjusting flow, level, pressure, temperature and wall thickness.
  2. For clear and contaminated liquids and gases. Also for (waste-)water applications.
  3. In existing constructions, retrofits and new constructions of a system, installation or section of pipes. Especially at sites where no efficient measuring solution was possible before, clamp-on ultrasonic flowmeters are now widely used.

HOW DOES IT WORK ?

Our ultrasonic measuring and adjustment instruments are based on the so-called ‘clamp-on’ principal. The sensors are mounted on the external wall of a tank or pipe. There is no contact with the medium inside. This is what makes clamp-on ultrasonic flowmeters ideal for measuring concentrations of toxic media, but also for example for slurries, air, scaling and pig detection.

ON SITE CLAMP-ON MEASURING

We perform clamp-on flow measurements on site. By means of our ultrasonic measuring solutions, your flow will be readable in no time. We are able to measure a whole series of pipelines quickly and accurately. Extensive reports are optional.
