3.7.2 Function
The following section describes the functional principle of the Y-style
flow-through assembly from the sample water inlet to the sample water
outlet. The installation of a ball valve on the input side is recommended.
Sample water inlet The sample water supply is connected on the input side via the 1/2” NPT
connection. A ball valve for setting the sample water flow must be pro
-
vided on site.
Optional strainer
(W3T158721)
The sample water flows over the optional strainer, which has a mesh size
of 0.5 mm and prevents dirt particles penetrating into the Y-style flow-
through assembly. The strainer must be provided on site.
Sample water outlet The sample water supply is connected on the output side via the 1/2”
NPT connection. The sample water outlet is not pressurized.
Sensor holder The pH or fluoride sensor is mounted in the sensor holder.
