Installation 

To install the meter proceed as follows: 

 

Determine the place of installation in line with the inscription on the meter. 

 

Note:

 At a 

heating meter

 or combined heating/cooling meter the 

mounting place of the flow sensor cold side is equivalent to return 
flow. The mounting place of the flow sensor hot side is equivalent 
to flow. 

 

Note:

 At a 

cooling meter

 the mounting place of the flow sensor 

hot side is equivalent to the return flow. The mounting place of the 
flow sensor cold side is equivalent to flow. 

 

Observe the dimensions of the meter and check whether there is sufficient 
space available. 

 

Rinse the system thoroughly before installing the meter. 

 

Fit the meter vertically or horizontally between two slide valves so that the 
arrow on the housing and the flow direction match. Also observe the instal-
lation situations and the following examples of installation. 

 

Fit the temperature sensors in the same circuit as the meter. Observe the 
admixtures. 

 

Seal the temperature sensors and the fittings to protect against manipula-
tion. 

 

Loosen the elastic band or the cable tie, provided for the transport, from the 
volume measurement unit. In operation, the temperature sensor and the 
control cable should not depend directly on the volume measurement unit. 

 

If you install the meter for cooling metering, follow the appropriate notes. 

Installation Notes 

Inlet or outlet sections are not necessary. If you install the meter in the com-
mon return of two circuits, determine a place of installation with a minimum 
distance of 10 × DN from the T-piece. This distance ensures a good thorough 
mixing of the different water temperatures. You can install the temperature 
sensors in T-pieces, ball valves, directly immersed or in pockets depending on 
the version. The temperature sensor ends must reach to at least the middle of 
the pipe cross section. 

 

Note:

 During installation it must be ensured that no water can 

enter the electronic unit during operation. 

Examples of installation 

 

 

 

 

Ball valve
