Introduction
to the Hydro-Flow™ Series
Vortex
flowmeters have been used in the process industry for over 15
years. Installations include refineries, chemical plants, pulp
and paper mills, etc. Their ability to measure a wide flow
range and no moving parts rugged design has made vortex
flowmeters one of the most widely used flowmeters for process
industry applications. Until Fluidyne™, the high cost of the
traditional vortex flowmeters made them impracticle for most
general water measurement applications.
Drawing
on over 15 years of vortex manufacturing experience, the
Fluidyne™ division has introduced a new generation of low
cost vortex flowmeters specifically designed for commercial
HVAC, turf and landscape irrigation, agriculture and
semiconductor water flow applications.
The
Hydro-Flow™ Series offers inline and insertion models,
covering most pipe sizes, flow ranges and installation
requirements. Each flowmeter is factory calibrated and scaled
to provide precise output signals. No complex field
adjustments or confusing measurement routines are required to
install the flowmeters. Simplicity of design, installation
convenience and reliability are unique features of Fluidyne's™
Hydro-Flow™ Series of vortex flowmeters.
Vortex...Nature's
Flowmeter
As
flow passes a bluff body in the flow stream, vortices are
alternately formed on either side of the bluff body. According
to well proven physical laws, the frequency at which vortices
are alternately formed is directly proportional to the average
flow velocity.
The
vortices create low and high pressure zones behind the bluff
body. A vortex flowmeter has a sensing element which detects
these low and high pressure zones and the frequency at which
they are created to measure flow.
The
fluttering of a flag is one example of how vortices are
created. The flag pole acts as a bluff body to the blowing
wind as the flag waves from the force of the vortices
alternately created.
Ultra
Low-flow Measurement Capability
Fluidyne's™
unique and proprietary microprocessor based piezo-resistive
sensor can accurately and reliably process vortex signals 25
times smaller than permitted by other technologies, producing
a flowmeter of unequal performance and reliability.
