9 Installation
9.1 Installation requirements
The water meter has built-in data communication, which enables remote reading of the meter.
If installed in pits or basements, the meter must (in some cases) be fitted with an external antenna in order
to secure optimum communication. The antenna must be placed outside pit or basement.
Prior to installation of the water meter, the system should be flushed, while a fitting piece replaces the
meter. Install the meter. Always use new gaskets in original quality.
Note! Mount the water meter with matching couplings, if needed.
Place the meter as required. The meter can be mounted at any angle, however, it should be installed
correctly in relation to the flow direction.
Flow direction is indicated by an arrow on the side of the meter housing.
Furthermore, the meter ought to be orientated in a way that the display is easy to read.
(see section
’Installation angle’ and ‘Straight inlet’
When mounting the water meter, you must ensure that the length of the meter thread will not prevent
sufficient tightening of the sealing surface, and make sure that PN10 or PN16 connections are used.
Kamstrup A/S recommends EPDM-gaskets for cold water installations and PTFE-gaskets for hot water
installations. Kamstrup A/S supplies such gaskets.
