HYGIENICDESIGN

 

The  body 

components  (s.s. 

version)  are  manufactured  from 

AISI  316  stainless  steel  and  are  ready  dismantled  for 
maintenance  and  cleaning.  Due  to  the  hygienic  design  and 
self-flushing  action,  the  mete,  lends  itself  to  in-line  steam 
sterilization. As a result the CRAIND IMPIANTI KPO meter 
is  used  in  a  wide  renge  of  applications  in  the  brewing, 
distilling, food ,drinks and pharmaceutical industries. 
 

CLEANING IN SITE 

When a system is to be cleaned in place, sterilized or purged 
without removal of the meter from the line, it is advisable to 
provi  de  the  meter  with  a  by-pass  to  prevent  damage 
occurring  to  the  internal  working  parts  unless  the  following 
reccommenations can be adhered to: 

 

Liquid  detergent  temperatures  in  excess  of  the  maximum 
stated  in  the  meter  speci at i on   should  not  be  used  for 
cleaning purposes or distortion and expansion of the piston 
will result, causing the piston to 

"

bind

"

 within the chamber. 

 

Check  that  cleaning  fluid  will  not  attack  or  corrode  the 
material of the meter. 

 

Sterelization with steam  is not admitted. If it is necessary 
the  pressure  of  the  in-coming  steam  to  the  meter  must  be 
carefully  controlled  so  that  the  velocity  of  the  piston 
within  the 

chamber 

is  kept  below  75%  of  its  maximum 

velocity  when  metering  with  liquids.  The  sane  must  be 
done when purging the system with air. 

 

After steam sterilization or air purging during re-charging 
of the pipe with fluid, care must be taken to avoid impact 
of high speed fluid re-entering the empty measuring 
chamber.
