The AFM flow meter for front and panel mounting are used for flow control of gas media in analysis devices and systems.
The Ankersmid AFM 10x flow meter consists of a vertical, internally conical glass tube widening towards the top in which a float can move freely upwards and downwards and of the head and bottom piece with an integrated Stainless Steel needle valve The sample gas flows upwards through the tube and lifts the float until a radial clearance occurs between the tube wall and the float so that forces affecting the body are in equilibrium. Every position of the float corresponds to a certain flow which can be read on a calibrated scale.
The measuring tube is sealed within the head and bottom part with FPM o-rings, as is the fine adjustment needle valve.
The flow meter is fitted with a fine adjustment valve in the inlet for precise flow value setting.
The Ankersmid AFM 20x flow meter consists of a vertical, internally conical glass tube widening towards the top in which a float can move freely upwards and downwards. A “front panel“ of a maximum 4 mm thickness with two appropriate mounting bore holes serves as base body for attaching the head and the bottom part.
The measuring tube is sealed within the head and bottom part with FPM o-rings. All parts coming into contact with the gas medium are made of PVDF, FPM and glass.
