To the Owner

 

Please read and retain this instruction manual to assist 

you in the operation and maintenance of this product.

 

 

The  manual  contains  operating  and  maintenance     

instructions  for  the  MX

-

Series  Flow  Meters  with  Ex 

outputs. This covers port sizes from 

1/4” 

to 

4”.

 

 

Refer to separate instruction manual for information on 

operating  modes  and  features  of  LCD  displays.     

Contact  local  representative  or  distributor  for  further 

assistance. 

 

  

 

This  Flow  Meter  has  incorporated  the  oval  gear      

principle  into  its  design.  Exceptional  repeatability  and 

high  accuracy  over  a  wide    range  of    fluid  viscosities 

and flow rates are features of the oval gear design. 

 

 

 

With a low pressure drop and high pressure ratings, 

oval  gear  flow  meters  are  suitable  for  gravity  and    

(in

-

line) pump applications.

 

 

Macnaught offer a comprehensive set of web based 

support  materials  to  complement  this  instruction   

manual.
