To the Owner 

Please read and retain this instruction manual to  
assist you in the operation and maintenance of this 
product. 
 
This manual contains connection and operating  in-
structions for  the MX series Flow Meters with Pulse 
outputs. 
   
Models with a Liquid Crystal Display have an addi-
tional LCD instruction manual  supplied. If  you need 
further assistance, contact your local representative 
or distributor for advice. 
 
This Flow Meter has incorporated the oval gear prin-
cipal into its design. This is proven to be a reliable 
and highly accurate method of measuring flow. 
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 rating 
oval gear flow meters are suitable for both  gravity  
and (in-line) pump applications. 

Macnaught offer a comprehensive set web based 
support materials to compliment this instruction  
manual.
