Function and system design Measuring principle Inductive conductivity measurement An oscillator (1) generates an alternating magnetic field in the primary coil (2), which induces a current flow (3) in the medium. The strength of the current depends on the conductivity and thus on the ion concentration in the medium. The current flow in the medium, in turn, generates a magnetic field in the secondary coil (4). The resulting induced current is measured by the receiver (5) and used to determine the conductivity. 1 5 A0004894  1 Inductive conductivity measurement

Advantages of inductive conductivity measurement:

• No electrodes and therefore no polarization effects
• Accurate measurement in media with a high degree of pollution and a tendency to form buildup
• Complete galvanic isolation of the measurement and the medium Input Measured variables Conductivity Temperature Measuring range Conductivity: Recommended range: 200 μS/cm to 1000 mS/cm (uncompensated) Temperature: –10 to 130 °C (14 to 266 °F)

• Linear with user-configurable temperature coefficient Reference temperature 25 °C (77 °F) Installation Mounting instructions Hygienic requirements ‣ Easily cleanable installation of equipment according to the criteria of the EHEDG must be free of dead legs. ‣ If a dead leg is unavoidable, it shall be kept as short as possible. Under no circumstances shall the length of a dead leg L exceed the pipe’s inner diameter D minus the equipment’s enveloping diameter d. The condition L ≤ D – d applies. ‣ Furthermore, the dead leg must be self-draining, so neither product nor process fluids are retained therein. ‣ Within tank installations, the cleaning device must be located so that it directly flushes the dead leg. ‣ For further reference, see the recommendations concerning hygienic seals and installations in EHEDG Doc. 10 and the Position Paper: “Easy cleanable Pipe couplings and Process connections”. For 3-A-compliant installation, please observe the following: ‣ After the device has been mounted, hygienic integrity must be guaranteed. ‣ The leakage hole must be located at the lowest point on the device. ‣ 3-A-compliant process connections must be used. Orientations The sensor must be completely immersed in the medium. Avoid air bubbles in the area of the sensor. > 1 (3.3) A0037970  5 Orientation of conductivity sensors. Engineering unit: m (ft) Changes in the flow direction (after pipe bends) can cause turbulence in the medium. 1. Install the sensor at a distance of at least 1 m (3.3 ft) downstream from a pipe bend. 2. 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.

In confined installation conditions, the walls affect the ionic current in the liquid. This effect is offset 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. The value of the installation factor depends on the diameter and the conductivity of the pipe nozzle as well as the distance a between the sensor and the wall. The installation factor can be disregarded (f = 1.00) if the distance to the wall is sufficient (a > 20 mm, from DN 60). If the distance to the wall is shorter, the installation factor increases for electrically insulating pipes (f > 1) and decreases for electrically conductive pipes (f < 1). It can be measured using calibration solutions, or a close approximation can be determined from the following diagram. a A0037972  6 CLD18 installation a Wall distance a [inch] 0 10 20 30 40 a [mm] 0.95 1 00 . 1.05 f 0.39 0.79 1.18 1.57 A0020517  7 Relationship between installation factor f and wall distance a
