Working principle

 

The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass. This free area is related to the flow rate, the weight of the float and the density and viscosity of the fluid. 

 

The pressure drop across the flowmeter remains constant over the entire flow range, since it is related to the fluid density and the float weight and dimensions. Flow indication is achieved since the area of flow increases as the flow rate increases.

 

Applications

• Water & waste water treatment
• Chemical & petrochemical industry
• Paper industry
• Pharmaceutical, cosmetics & synthesis
• Refrigeration & air conditioning
• Refining
• Osmosis
• Gas processes

Features

• Low cost, excellent readability and light weight
• Simple installation (flanged, threaded or socket ends for solvent or fusion welding connections)
• Wide range of operating temperatures with several combinations of tube and fittings materials
• Scaled directly in l/h, m3/h, %,... Special scales for liquids and gases on request
• Flow rate:

          - Water: 4 l/h ... 50 m3/h
          - Air: 200 Nl/h ... 1500 Nm3/h
