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
