How to connect the UP56 Pure ultrasonic level sensor to a tank or pipe

The UP56 Pure ultrasonic level sensors feature a process connection compatible with Georg Fischer Piping Systems (GFPS).

Components such as pipes and fittings compatible with GFPS can be connected by screw joints with union nuts, which are dimensioned according to the designation “d” (picture 1). The value of d refers to the inner diameter (in mm) of the pipe or socket that contains the thread. Pipes, connectors, unions, and seals are available in various materials to suit different applications.

For all UP56 Pure sensors, the process connection size is d40, meaning the inner diameter of a Georg Fischer pipe "d" is 40 mm. In the example shown below (picture 1), the pipe on the right side (d2) is replaced by the UP56 Pure sensor, while the left side (d) represents the socket or pipe (immersion tube or bypass tube) connected to the tank.

The connection between the socket and the tank or pipe is typically achieved through fusion welding or adhesive bonding, both of which are standard techniques in plastic piping installations.
