Influence of flow controllers on ultrasonic flowmetersInfluence of flow controllers on ultrasonic flowmeters
The operating principle of an ultrasonic flowmeter is based on the use of sound waves. This means that this type of flow meter is sensitive to sonic disturbances. In any measurement environment there will always be some form of sonic noise. Up to a certain point this is not a problem. When does it become…
Tailor-made distribution block for clean room application
VDL Klima and Teesing have worked together for many years, including on components for liquid based temperature controlling systems. This involved design, assembly and delivery. This story is about how in that collaboration you sometimes take a trip: the starting point is the first idea and together you eventually arrive at a modified design.
Gasunie is responsible for the natural gas distribution network in the Netherlands. The main transport pipeline, which runs roughly around the IJsselmeer, is 1.06 m in diameter (42″) and has a nominal pressure of 67 bar. Gasunie uses ultrasonic flow meters for flow measurement. What are the considerations for choosing an ultrasonic flow meter in…Measuring natural gas at 67 bar and with 1m diameter
A nice example of co-engineering and cleanroom assembly
Testing electronics under cleanroom conditions and in a vacuum is a challenge. Especially when it concerns high voltage electronics. In this case the customer needs a vacuum chamber that is able to test electronics under high vacuum (10-7 mbar). It is an ultra high purity application with a cleanliness of Grade 2 on the inside and Grade…

A MAGMETER WITH 30% ERROR?
Inventing and making specialty firefighting vehicles is what Innovative Fire Fighting Solutions (IFFS) is strong in. They focus mainly on systems for extinguishing water and hose systems. Fire trucks all have their own requirements regarding the amount of water on board, the flow and the distance over which water must be transported. For measuring the…
Micro Turbine Technology in low flow applications
In the sequence of our webinars about flow measurement techniques, we have added turbine technology. This type of flowmeter has a turbine, a rotor, placed axially that rotates faster as the medium flows through the instrument faster.
