AFM流量计可安装在前面或面板上，用作测量装置和气体调价装置中气体介质流量的控制。它由一个垂直、内部倒置圆锥形的丙烯酸管和一个带有不锈钢针形阀的外部结构组成。锥形管渐高渐扩的构造，使得浮子可以自由上下移动。
气体样品从中间自下而上流过，托起浮子，浮子和管壁之间出现一个径向间隙使气流通过。浮子的位置对应一定的流量，可以从校准过的刻度上面读出。针形阀可以精确控制气体流量。
Ankersmid Flow Meter
AFM 10X
Application
The acrylic AFM 10X flow meter for front and panel mounting is used for flow control of gas media in analysis devices and systems.
Description
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 effecting 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.
AFM 20X
Application
The compact, flat, corrosion resistant AFM 20X flow meter for front panel mounting is used for flow control of gas media in analysis devices and systems.
Description
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.
