Mass flow or air flow testing uses flow measurement devices to calculate leak rates based upon the rate of air flow through the device. This technique is suitable for small and large volumes and is often applied to test kitchen appliances, gas meters, exhaust systems and other products where gas or air is required to flow through the item.
As a leak testing technique, mass flow measurement is very useful for detecting small leaks in large volumes. When selecting a mass flow tester it is important to select the correct flow meter range to ensure that the desired amount of sensitivity is achievable. Uson’s leak test application engineering group are available to help you with this.
