    5 Mounting 5.2 Fastening the flow indicator to a pipe There are various versions of the flow indicator, depending on various factors (e.g. coolant used, electrical connection, flange design). The display part and transmitter part are adjusted to one another at the factory and have identical serial numbers. Only attach transmitter parts and display parts together that have identical serial numbers.
  • Page 22 5 Mounting Proceed as follows to fasten the flow indicator to the pipe: 1. Loosen the screws on the display part and remove the display part from the transmitter part. Figure 4: Removing the display part 2. Fasten the transmitter part with gasket on the flange such that the im- printed arrow points in the flow direction of the cooling medium.
