Probe Riser Pipe Installation
A riser assembly consisting of a riser (either 2- or 3-inch [50.8 or 76mm] nominal bore galvanised steel pipe
threaded 2- or 3-inch BSPT at each end) and a 2- or 3-inch riser cap, designed specifically for the efficient
installation of Veeder-Root magnetostrictive probes, should be used for Mag Probe installation (see
Figure 16).
Riser caps are normally fitted at the time of probe installation by Veeder-Root authorised engineers. An optional
cable shield is available for 3-inch (76mm) riser caps, if required.
Non–standard or locally supplied risers may be made from 2- or 3-inch nominal bore galvanised steel pipe
threaded 2- or 3-inch at each end (see
Table 2 for allowable riser dimensions).
Remove the plug from the tank socket. Install a 2-inch (50mm nominal bore) or 3-inch (80mm nominal bore) riser
using an appropriate thread-sealing compound. Reducers are available for 4-inch (102mm nominal bore) sockets.
If the probes are not to be installed immediately, cap the riser.
Where locally supplied, 2-inch risers should be seamless, have a 2-inch ID, and be free of burrs.
