1. "Angle selection" menu item:

Select the pipe standard, the diameter, and the size of the SISTO-C 2-way diaphragm valve to be welded in. Then press the Start angle measurement button.

2. “Start angle measurement” menu item:

The selection of the SISTO-C 2-way diaphragm valve is described again in the upper area. The target installation angle has been given. The actual installation angle is displayed dynamically as a number. The text is highlighted in red.

In the graphic, the target installation angle is depicted by black lines on the right and left sides. The actual installation angle is depicted dynamically by purple lines. The graphic has a red background.

3. Perform angle measurement:

Place your smartphone with the long edge on the seat of the SISTO-C 2-way valve housing.

By tilting the valve housing to the right or left side, the actual installation angle changes in the graphic and the number changes in the upper area. When the correct self-draining angle has been achieved, the background colour changes from red to green, and you will also hear an audible signal.

The correct self-draining angle is set when the target and actual installation angles are identical, the background colour is green and the audible signal sounds.

Note: This app is not a measuring instrument. When using it to align valve housings, we recommend comparing it with a calibrated reference.
