General Notes 1.1 Explanations of the symbols Warning of a danger place (caution: consider documentation) ISO 3864, No. B.3.1 1.2 General Hints For reasons of clarity this manual does not contain detailed information about all types of products and cannot take into account every conceivable case of installation, operation or maintenance. If you require further information or should problems occur which are not sufficiently explained in the manual, you can consult us directly to obtain the necessary information. -
Page 4: Incoming Inspection
Incoming inspection Each delivery leaving S.K.I. GmbH is carefully inspected to the best knowledge. On the packing list included, the employee responsible for the delivery confirms with his signature that the delivery contains all the items specified in the delivery documents. Nevertheless, it is necessary for the customer to carry out a crosscheck as soon as possible after receipt of the delivery. -

be mounted horizontally. The alignment of the sensor for both horizontal pipe run and vertical pipe run is shown in the drawing below. 4.4 Orientation of the SDF flow sensor The construction of SDF flow sensors is completely symmetrical. For this reason it is irrelevant which of the apertured sensor sides faces the flow. - Page 8 union nut necessary torque (TA) in acc. to ISO 9974-1/ ISO 6149-1/ DIN 3852-T1- cutting ring Form X/ DIN 3652-T3-Form W (metr. thread) of mounting-part for SDF-M: SDF-M-10: TA ≈ 150 Nm SDF-M-22: TA ≈ 250 NM welding socket SDF-DM-10 At the mounting location determined the pipe wall must be provided with a 21 mm diameter hole by boring or burning.

directly adjacent to the marked mounting part centre. The distance from the start of the tape to this point is equal to the outer diameter of the pipeline. Remove the tape, determine the centre between the start of the tape and the point marked on the tape, and mark the centre of the tape. - Page 10 SDF-DF-22 The procedure corresponds to the one of sensor SDF-DF-10.

Page 11: Connecting The Differential Pressure Transmitter To The Sensor
Connecting the differential pressure transmitter to the sensor The transmitter and the sensor are connected via differential pressure lines. Usually pipes are used which are connected to the condensate vessels and the transmitter by means of screwed connections or by welding. For low presure applications usually screwed connections with cutting or clamping rings are used which allow the process connections to be adapted to the selected pipe connection with a diameter of 12 mm. -
