S-100 Series



S-102/S-752are variable area flowmeters for flow measurement of liquids which contain solids. The movement of float can be visually checked through upper sight glass and the flow rate is indicated by the position of float and the scale plate on the glass tube. Local indication version S-102 and alarm contact version S-752 are available.


Special float design makes it possible to measure liquids containing solids or fiber by providing escape routes for slurries.PVC material for sewerage system can be arranged.
Alarm contact version is available.
