Condumax CLS15D/16D/21D Installation
Hauser 15
4.1.2 CLS16D
The sensors are installed directly via the process connection.
‣
When installing in pipes, pay attention to the flow direction.

 4 Inadmissible flow direction
1. Ensure that the electrodes are fully immersed in the medium during measurement.
2. If using the sensor in the ultrapure water range, you must work under air-evacuated
conditions.
 Otherwise, the CO
2
in the air can dissolve in the water and its (weak) dissociation
can increase the conductivity by up to 3 µS/cm.

Clamp connection
Both sheet-metal brackets and solid brackets can be used to secure the sensor. Sheet-
metal brackets have a lower dimensional stability, uneven bearing surfaces causing point
loads, and sometimes sharp edges that can damage the clamp. We recommend you only
use solid brackets due to their higher dimensional stability. Solid brackets can be used
over the entire pressure/temperature range (see pressure-temperature ratings).
