Omega Engineering FPR 200 - Manual (Page 3)

Introduction
This manual is a service guide produced by the manufacturer. The
manual provides specific procedures and/or illustrations for installa-
tion, inspection, cleaning and filtration of all Omega FPR 200 flow
sensors. When properly followed, these procedures will keep your
flow sensor operating dependably for many years.
It is important for operators and maintenance personnel to be safety
conscience when operating or repairing equipment. Developing a thor-
ough knowledge of the precautionary areas and following safe operat-
ing 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.
General
Omega’s flow sensors integrate rugged tangential turbine technology
with a precision digital to analog conversion circuit hermetically
encapsulated within the body of the sensor. The flow sensor is ideal
for measuring flow rates in cooling circuits, HVAC systems and batch-
ing operations.
Additional features are:
„ simple in-the-field serviceability of its moving components
„ the integral 4-20mA circuit design eliminates the need for separate
signal conditioning modules
„ units come factory calibrated to your system requirements
„ the low impedance 4-20mA circuit can transmit a "clean" signal
over low-cost wire for several thousand feet without degradation
„ accurately measures flow in both directions.
