Liquid filters are recommended to be used, in order to protect flowmeters from abrasive particles and clogging. The use of a deaerator tank is to prevent, especially at start up, large quantities of air or gas entering the process liquid.

Liquid filters /deaerators are available in connection sizes from 15 mm up to 300 mm representing maximum flow ranges from 50 l/min up to 16000 l/min. Steel and stainless steel models are available.

VAF Instruments liquid filters/deaerators are suitable for a wide range of liquids and they are especially developed for filtering and deaerating of all kind of hydrocarbon liquids.
