21 6 Installation 6.1 General Installation location The compatibility of the material with the measurement medium must be checked by the customer. Ensure easy accessibility for subsequent calibration. The fastening must be secure and low-vibration. Avoid direct sunlight. It is necessary to pay attention to a good flow through and around the sensor (1). When installing in a pipe, a minimum distance of 20 mm must be maintained from the sensor to the pipe wall. If these minimum distances cannot be maintained, the parameter «Mounting factor&quot

11 3 Inductive conductivity measurement 3.1 Range of Applications General The inductive measurement process allows a mostly maintenance-free acqui- sition of the specific conductivity even in difficult medium conditions. In con- trast to the conductive measurement process, problems like electrode replacement and polarization do not occur. Brief descrip- tion The device is used for the measurement / control of the conductivity / concen- trations of liquid media. U
