3. Measure and record the following distances –
see Fig. 2.5:

A
of the valve .
— length of compression fitting after insertion into the
B ?
reducer
— pipe/vessel wall thickness
— sensor insertion depth

the valve until the mark made at 4 reaches the
compression fitting.
7. Tighten the outer compression joint (manually or using a
wrench depending on type of fitting chosen).
8. A mark can also be made distance B from the tip of the
probe. This can then be used to tell when the valve can be
