1 Liquid filters Deaerators _ 32 Product Bulletin

2 Introduction VAF Instruments liquid filters/deaerators are used in combination with VAF flowmeters. The use of liquid filters protects downstream equipment against abrasive particles and clogging. The sturdy, compact construction and the particularly large filtering area ensure that these liquid filters are on the safe side even in tough and unfavorable conditions. The design permits trouble free operation at all time and easy cleaning. The use of a dearator tank is to prevent, especially at start up, large quantities of air or gas entering the process liquid. Experience in flow measurement In 938 VAF Instruments started as a manufacturer of petrol delivery pumps. The flowmeters made by VAF Instruments for this pump had to have the highest accuracy and had to meet the demands of the board of weights and measures. Innovation and research over the past 75 years helped VAF Instruments to make new types of flowmeters bearing in mind customer requirements and the need for accurate flow measurement also in combination with liquid filters or dearators. Available liquid filter / deaerators Liquid filter/deaerators are available in connection sizes from 5 mm up to 3 mm representing maximum flow ranges from 5 l/min up to 6 l/min. Steel and stainless steel models are available. Liquids VAF Instruments liquid filters/deaerators are suitable for a wide range of liquids. Especially developed for filtering and deaerating of all kind of hydrocarbon liquids. Special versions This brochure comprises only VAF Instruments standard delivery program. Special flowmeter variants can be offered as tailor-made solutions. 2

4 Technical specification Pressure drop The pressure drop across the filter must not exceed,8 bar (8 kpa). Higher pressure drops increase the risk of filter element failure. The pressure drop data given below are based on filter elements with the smallest mesh size available. Data for versions not shown are available on request. Air vent/deaerator Liquid filters can optionally be provided with a top mounted air vent. The purpose of this feature is to automatically expell small to medium quantities of air or gas from the process liquid. Especially important at the initial start-up. The air vent is not suitable for continuous venting of large quantities of air or gas. In this case a separate deaerator tank should be installed upstream of the flowmeter.,8,6,4,2,8,6,4, mpa.s 5 mpa.s 5 mpa.s mpa.s mpa.s mpa.s,8 Filter DN5 (½ ) Filter DN25 ( ) Filter DN4 (½ ),6,4, mpa.s mpa.s mpa.s,8 Filter DN5 (2 ),6,4, mpa.s mpa.s mpa.s Deaerator tank Housing Steel Connection size DN 5 (2 ), 8 (3 ), (4 ), 5 (6 ), 2 (8 ) Flange connections DIN PN, ANSI 5 RF, ANSI 3 RF Max. working pressure [bar] Vent outlet ¾ NPT,8,6,4,2,8,6,4,2 Filter DN8 (3 ) mpa.s mpa.s mpa.s Filter DN (4 ) mpa.s mpa.s mpa.s 4
