Stainless steel ball-float flow meter with needle valve and hose connection

Stainless steel flow meter and flow switch for very low flows of liquids and air. The float is a ball, and the flow rate is read at its upper edge. In addition to threaded connections, a hose connection for 8 mm tubing is available, which is convenient for laboratory set-ups or flexible lines.

Features

• Water: from 0.25…2.5 l/h to 16…160 l/h
• Air: from 0.5…5 Nl/h to 500…5,000 Nl/h
• ¼" NPT, G ¼ female or hose connection for 8 mm tubing
• Maximum pressure 16 bar, maximum temperature 100 °C
• Accuracy ±2.5 % at qG = 50 %
• Needle valve fitted as standard
• Options: contacts, upstream or downstream differential pressure regulator

Operating principle

The instrument works on the suspended float principle: installed vertically, it is crossed by the medium from bottom to top. Its simple construction makes it an economical choice for setting and checking small flows.
