In non-metallicvessels, the distance to the vessel wall should be at least 500 mm(19.7 in).During operation, the probe must not touch any installations or thevessel wall. If necessary, fasten the probe end.In vessels with conical bottom it can be advantageous to mount thesensor in the center of the vessel, as measurement is then possiblenearly down to the lowest point of the bottom. Keep in mind thatmeasurement all the way down to the tip of the probe may not be pos-sible. The exact value of the min. distance (lower dead zone) is statedin chapter "Technical data" of the operating instructions.Fig. 2: Vessel with conical bottomProtection against mois-tureInstallation position
