WARNING: Your warranty will be voided if your unit is not installed in accordance
with this user's guide. Make sure you read and thoroughly understand the
installation portion of this guide before you attempt to install your unit. If you
have any questions, contact your Kurz customer service representative before
attempting installation.
Mounting
The 504 and 534FTB In-line flow transmitters are generally mounted with a flange pipe
fitting but thread is sometimes used on smaller line sizes. See the product brochures
(DCN
367524
for the 504FTB and DCN
360723
for the 534FTB) for Kurz mounting
accessories. It is important for the mounting design to consider the force that will be
exerted on the flow body from the piping. It is best (often required by the plumbing
code) to support the process piping on both sides of the flow meter so it may be
removed without the piping bending or moving much making it hard to re-install.
Flow Body Location and Orientation:
The In-Line flow meters are available for ½" to 6" piping. The principle difference
between the 504FTB and 534FTB is the type and efficiency of flow conditioner which
