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 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.
