Float-Type Flow Meter Series FM® Versions FM-1, FM-10
●Description
■The FM-1 and FM-10 float-type flow meters consist of an upright glass tube conically wid- ening inside towards the top, in which a float- ing ball can move freely up and down. The medium flows from the bottom to the top through the tube and lifts the floating body until there is a ring-shaped gap between the tube wall and the floating ball so that the forces acting on the body are in equilibrium. Each height position of the floating ball corre- sponds to a certain flow rate, which can then be read on a calibrated scale.
■Sealing and connecting points have been reduced in design down to the inlet and out- let connections. All parts in contact with the medium are made of glass or PTFE.
■The flow meters can be dismantled in a few simple steps and are therefore easy to clean. The FM-10 flow meter is supplied with a fine adjustment valve at the inlet for precise flow value adjustment.
◆For automatic flow monitoring, the optical control unit types FA... are used. Please see separate data sheets "Optical Bi-Stable Flow Alarm Sensors Series FA®", "Electronic Controller Series FA®" and "Optical Flow Monitoring Series FA®".
◆For connecting the tubes, a special range of connecting fittings is available. Please see separate data sheet "Fittings for GL Glass Connections".
