It is the policy of OMEGA Engineering, Inc. to comply with all worldwide safety and EMC/EMI
regulations that apply. OMEGA is constantly pursuing certification of its products to the European New
Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.

The information contained in this document is believed to be correct, but OMEGA accepts no liability for any
errors it contains, and reserves the right to alter specifications without notice.
WARNING: These products are not designed for use in, and should not be used for, human applications.

This manual is a service guide produced by the manufacturer.
It provides specific procedures and/or illustrations for installation,
inspection, cleaning and filtration. When properly followed, these
procedures will keep your FLMW 200 Series flow meter or indicator
operating dependably for many years.

It is important for operators and maintenance personnel to be safety
conscience when operating or repairing equipment. Developing a
thorough knowledge of the precautionary areas and following safe
operating procedures can prevent equipment damage and/or personal
injury. Before making any repair, read all of the repair procedures to
learn the correct method and all precautions.

Operating Theor y

The FLMW 200 Series flow meter has a low mass axial turbine
which is urged towards zero flow rate by a precision torsion spring. As
fluid flows past the turbine blades, a rotational torque is imposed onto
the turbine and spring causing the turbine to rotate to a position
where the spring's return force equals the fluid torque. Since variable
fluid flow rate causes variable fluid torque, flow rate is measured by
correlating turbine rotational displacement to flow rate.

The FLMW 210 Series flow indicator operates without the torsion
spring, allowing the turbine to spin freely within the fluid stream. A
chart on the side of the indicator approximates turbine RPM to GPM.
