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 FlowStat and FlowStat ES
flow sensors. When properly followed, these procedures will keep
your FlowStat flowmeter 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
Lake Monitors' FlowStat flow rate sensors integrates rugged tangen-
tial turbine technology with a precision digital to analog conversion
circuit hermetically encapsulated within the body of the sensor. The
flow transmitter is ideal for measuring flow rates in cooling circuits,
HVAC systems and batching 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.
