3. Information ‘E’ codes

MULTICAL

601 continuously monitors a range of important functions. In case of

serious damage in the measuring system or installation, an ‘Info’ note appears on the

display. The information code can be read by pressing and holding the left top button,

until the ‘Info’ note shows up on the display. The information code only appears if

there is an error.

4. Assembly of the flow section

Before the assembly of the flow section, carefully wash the system and remove

protective lids (plastic diaphragms). The correct flow meter position (in supply and

return piping) is shown on the label of the MULTICAL

601 front. The direction of the

flow is marked with an arrow on the side of the flow meter.

Pipe union and sealing must be mounted as given in the picture. ULTRAFLOW

does

not require any direct sections in front of and behind the meter; however, to reach the

optimal installation conditions, we recommend the following:

Dimensions Recommendation

DN15 to DN80 qp 0.6 to qp 40 Min. 5 x DN in front of the meter

DN100 to DN250

qp 60 to qp 1000

Min. 10 x DN in front of the meter

Min. 3 x DN in front of the meter

CEN CR 13582 installation requirements must be followed.
