Dynasonics MFX Series Insertion MagProbe Flow Meter - Manual (Page 28)

Rev. 01/11 -2.3- MFX
The installation instructions cover hot-tapped installations
(installations where it is required to install or remove the MagProbe
without shutting down the process pressure). If the product is being
installed without an isolation valve, ignore the steps that pertain to
its installation. Figure 2.2 illustrates an exploded view of an
isolation valve assembly and names the various components.
Hot-tapped installation will require the installation of either a welded
pipe coupling or installation of a pipe saddle. The ball valve and
close nipple can be purchased as a kit from Dynasonics or can be
procured at most hydraulic or plumbing supply shops. The two
critical factors that must be considered with the components are
pressure rating and internal sizes. The DMP2 through DMP6 1-½"
MagProbes are designed to operate with pipe pressures up to 700
psi (48 Bar). Verify that the internal port of the opened valve is at
least 1-½ inches (38 mm) to permit free passage of the probe
without interference. Attempts to force a MagProbe through an
opening smaller that stated will damage the probe tip and void the
warranty. Step B -
