OPERATING PRINCIPLE

The flow path has a tapered part. A float in which amagnet is moulded is located in the tapered tube. Thefluid is introduced from the bottom end of flowmeterand goes through the tube upward.Because of the differential pressure produced by thefloat and tapered tube, the float is pushed upward andstops at a position where the weight of float and thedifferential pressure balance. Thus, the position of floatcorresponds to the flow rate. The moulded magnet inthe float attracts the pointer, and the pointer indicatesthe flow rate on the scale plate.The inside of the tube and indication mechanism aretotally isolated by magnetic coupling.

cates flow rate of liquids and gases by scale plate and pointer.

Operation is purely mechanical and no utilities, i. e. electric or pneu-

matic supply is required.

attracted by the magnet in float and operation will be interrupted.

To avoid this kind of problem, it is recommended to install a Magnet

Strainer at the upstream of flowmeter.
