Installation Proline Promass 833.2.4 Special installation instructions"Caution!Promass F, E, H, S, P and OIf the measuring tube is curved and the unit is installed horizontally, adapt the sensor position tothe fluid properties.Fig. 9: Horizontal installation of sensors with curved measuring tube.1 Not suitable for fluids with entrained solids. Risk of solids accumulating.2 Not suitable for outgassing fluids. Risk of air accumulating.Promass I and P with Eccentric Tri-clampsEccentric Tri-Clamps can be used to ensure complete drainability when the sensor is installed in ahorizontal line. When lines are pitched in a specific direction and at a specific slope, gravity can beused to achieve complete drainability. The sensor must be installed in the correct position with thetube bend facing to the side, to ensure full drainability in the horizontal position. Markings on thesensor show the correct mounting position to optimize drainability.Fig. 10:Promass P: When lines are pitched in a specific direction and at a specific slope: as per hygienic guidelines (21 mm/m or approximatley 2%). Gravity can be used to achieve complete drainability.1 The arrow indicates the direction of flow (direction of fluid flow through the pipe).2 The label shows the installation orientation for horizontal drainability.3 The underside of the process connection is indicated by a scribed line. This line indicates the lowest point of theeccentric process connection.Page 18 • MN0M022Issue/Rev. 0.2 (12/12)
