There are times with medical instrumentation and in medical device manufacturing when it is necessary to determine the internal volume of a part. The examples provided here illustrate the advantages of using gas with mass flow, pressure and temperature sensors to measure even difficult volumes.
Select the right method
In medical instruments and in medical device manufacture it is often important to determine bag volume, control balloon volumes or determine the cavity size in moulded parts. Trying to measure these geometries by length measurements can be difficult, if not impossible. It is possible to use a liquid to fill the part to calculate the volume, ...
