Indumax CLS54 Installation 4.1.2 Installation factor The ionic current in the liquid is affected by the walls in confined installation conditions. This effect is compensated by what is referred to as the installation factor. The installation factor can be entered in the transmitter for the measurement or the cell constant is corrected by multiplying by the installation factor.
Installation Indumax CLS54 Installing the sensor A0028428 4 Installation of CLS54, arrow indicates direction of flow When installing, align the sensor in such a way that the medium flows through the flow opening of the sensor in the direction of medium flow. The sensor head must be completely immersed in the medium.
