OVAL GEAR FLOWMETER SERIES
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
instructions for the MX series Flow Meters with
Pulse outputs.
Models with a Liquid Crystal Display have an
additional 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
principal 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
MX06 - MX100
