Mounting Of Flow Sensor; Mounting Of Couplings, And Short Direct Sensor In Multical® 403 Flow Sensor - Kamstrup MULTICAL 403 Installation And User Manual

MULTICAL® 403

3 Mounting of flow sensor

Prior to installation of the flow sensor, the system should be flushed and protection plugs/plastic
diaphragms removed from the flow sensor.
Correct flow sensor position (inlet or outlet) appears from the display of MULTICAL® 403. Mounting
in inlet pipe is symbolised by , whereas mounting in outlet pipe is symbolised by . The
flow direction is indicated by an arrow on the flow sensor.
3.1 Mounting of couplings, and short direct sensor in MULTICAL® 403 flow sensor
The short direct sensor from Kamstrup may be
installed in PN16 installations only. The blind
plug which is mounted in the MULTICAL® 403
flow sensor from the factory can be used in
connection with both PN16 and PN25.
The flow sensor can be used in both PN16 and
Gasket
PN25 installations and is available with either
PN16 or PN25 marking as required.
Torque ~4 Nm
Enclosed couplings, if any, are only intended for
PN16. Suitable PN25 couplings must be used in
PN25 installations.
Straight inlet: MULTICAL® 403 neither requires straight inlet nor straight outlet to meet the
Measuring Instruments Directive (MID) 2014/32/EU, OIML R75:2002, EN 1434:2007 and EN
1434:2015. A straight inlet section will only be necessary in case of heavy flow disturbances before
the meter. It is recommended to follow the guidelines of CEN CR 13582.
