4.4. Mounting the sample connections
4.4.1. Important information when mounting the sample
connections
Observe the following points when mounting the sample connections:
Only an non-return valve type EA tested and certified according to EN 13959 must be
used.
Only hoses tested and/or certified according to EN 13618 or EN 61770 must be used.
All the hoses must be secured with clamping straps . Two weeks after mounting, all
the connections must be checked for leakage to avoid any air suction.
In order to ensure an accurate measurement of the turbidity, observe the following points
when mounting the sample connections:
A continuous water flow rate as specified in the technical data is required (

Sec-
tion2.4). If the required water flow rate is exceeded or undershot, measuring e rrors
may occur!
Large drops in the pressure must not occur; if that happens, air bubbles may occur.
A regulator valve should always be used for adjusting the water flow rate and for
generating the counter pressure in the measuring cell on the sample outlet.
The use of transparent hoses is not permitted.
