1. General information Read this guide before installing the meter. In case of incorrect mounting Kamstrup’s guarantee obligations no longer apply. Please note that the following installation conditions must be obeyed: - Pressure stage PN16/PN25, see marking. The flow sensor marking does not apply to...
Page 7: Pocket Sensor Set
Pocket sensor set Preferably, sensor pockets must be mounted in tee-pieces or in 45° lat- eral Y-pieces. The tip of the sensor pocket must point against the flow direction and be placed in the middle of the water flow. Temperature sensors should be inserted to the bottom of the pockets. If a short response time is required, “non-hardening”...

Page 9: Mounting Of Flow Sensor
Mounting of glands and short direct sensor mounted in MULTICAL®402 flow part The short direct sensor from Kamstrup can only be mounted in PN16 installations. The blind plug mounted in the MULITCAL® 402 flow part can be used in connection with both PN16 and PN25.
Page 10 Gasket Gasket Tightening approx. 4 Nm The flow meter can be used in both PN16 and PN25 and can be sup- plied marked either PN16 or PN25 as desired. Possibly supplied glands can only be used for PN16. For PN25 installa- tions shall be used suitable PN25 glands.
