Stainless steel ball-float flow meter with needle valve and 90 mm centre distance

Flow meter and flow switch for small flows of liquids and air, with a ball-shaped float and 90 mm centre distance. The instrument is built in stainless steel and conceived as a simple, cost-effective measuring system. The needle valve, supplied as standard, allows the flow to be set directly on the instrument.

Features

• Water: from 0.02…0.25 l/h to 10…100 l/h
• Air: from 2.0…20 Nl/h to 300…3,000 Nl/h
• ¼" NPT or G ¼ female connections
• Maximum pressure 16 bar, maximum temperature 100 °C
• Accuracy ±3 % at qG = 50 %
• Needle valve fitted as standard
• Options: contacts, upstream or downstream differential pressure regulator

Operating principle

Operation is based on Archimedes' principle: installed vertically with upward flow, the instrument uses a ball as its float, and the flow rate is read at the top of the ball.
