Fig. 4: Measures against moisture penetrationThe reference plane for the measuring range of the sensors isthe sealing surface of the thread or flange.Keep in mind that a min. distance must be maintained belowthe reference plane and possibly also at the end of the probe -measurement in these areas is not possible (dead band). Keepin mind that the cable length cannot be used all the way to theend because measurement in the area of the gravity weight isnot possible. These min. distances (dead bands) are listed inchapter "Technical data".The process fitting must be sealed if there is gauge or lowpressure in the vessel. Before use, check if the seal material isresistant against the measured product and the processtemperature.The max. permissible pressure is specified in chapter"Technical data" or on the type label of the sensor.4.2 Mounting instructionsMount VEGAFLEX 62 in such a way that the distance to vesselinstallations or to the vessel wall is at least 300 mm (12 in).During operation, the probe must not touch any installations orthe vessel wall. If necessary, fasten the probe end.In vessels with conical bottom it can be advantageous tomount the sensor in the center of the vessel, as measurementis then possible down to the lowest point of the bottom. Whenusing the cable version, keep in mind that measurement downto the tip of the probe is not possible.
