The in-line water meter with potential-free pulse signal
is suitable for use in flow-proportional dosing
applications.
• Qn 1.5 and Qn 2.5 meters are of the multi-jet, dry
dial type, for cold water up to 30 °C, or hot water up
to 90 °C.
• Qn 15 meters and up are of the helical vane type,
for cold water up to 50 °C, or hot water up to 120 °C.
• Max. pressure: 16 bar.
If the water meter is connected directly to the pump
pulse input, use a control plug (PN 96698715).
• Qn 1.5 to Qn 15 meters are threaded.
• Qn 40 to Qn 150 meters are flanged.
• Cable length: 3 m.
