Plastic flow meter and flow switch with threaded or solvent-weld connections DN 10…25

Float-type flow meter made of plastic for measuring and monitoring flow in closed pipework. The tapered metering tube is plastic, with the scale marked directly on it for an immediate reading. Fitted with the optional contact, the instrument also works as a flow switch.

Features

• Water: from 1.5…11 l/h to 100…1000 l/h
• Air: from 0.15…0.45 Nm³/h to 20…105 Nm³/h
• Male threaded connections from G ¼ to G 1 or solvent-weld ends from DN 10 to DN 25
• Materials: trogamid, polysulfone
• Nominal pressure PN 10, maximum temperature 100 °C
• Accuracy class 4
• Options: contact, air scale

Operating principle

The medium enters from below and rises through the tapered metering tube, lifting the float. The position reached by the float corresponds to the flow rate, which is read on the tube scale.
