Corrosion Resistant and Ultra-Pure
Rotameters for Accurate Measurement of Liquids and Gas
George Fischer Plastic Rotameters are vertical flow meters for measuring the rate of flow of liquids or gas in indus-trial piping systems. Our wide lection of materials and measurement scales allows our rotameters to be ud in a broad range of applications and media.
George Fischer UPW Rotameters are designed specifically for measuring the flow of liquids or gas in applications which require ultra-pure conditions. The rotameters are designed without any dead spaces and are specially cleaned and bagged for high purity.
Markets/Applications George Fischer rotame-ters are ideally suited for a multitude of corrosive and sanitary process in the industrial markets:
Beverages
Biotechnical Sciences Brewing Chemical Confectionery Cosmetics Distilling Electronics
业绩提升Fertilizers & Agricultural Chemicals
Food Processing Manufacturing
Industrial Equipment Marine
Metal Working Mining Oils Paint
Pulp & Paper Petroleum & Oil Photographics Pollution Control Power Printing
Water & Water Treatment
Shatter-proof
George Fischer high impact plastic
rotameter tubes are durable and virtu-
ally shatter-proof. They are the perfect
alternative to fragile glass and expen-
sive armored flow meters.
Accuracy
Dual Scales
The George Fischer rotameter is a highly
accurate fluid flow instrument. Accuracy
is rated at 3% of full scale, 1% of
measured range. The float stops include
flow-straightening vanes. The allow for
accurate measurement even if con-
nected directly to a tee or elbow.
George Fischer rotameters do not
require a ction of straight pipe to
straighten the flow, making them ideal
for applications where limited space is
an issue.
Easy to Read
George Fischer rotameters are equipped
with adjustable guides for easy visual
readout. Bright orange-colored floats
are clearly visible, even from a distance.
George Fischer rotameters have been
designed as dual scale units. This
enables people at different locations to
quickly and accurately communicate
actual process flow conditions without
having to convert units. Scales are
offered in GPM, LPH, % and cubic
meters per hour for water. Special scales
are available for SCFM (air), NaOH
33%, NaOH 50%, and HCI 33%.
(Currently, the short version has one scale
only.)
Modular Design
The modular design makes our rotame-
ters very versatile. It allows the ur to
design the correct rotameter configura-
tion for a given application. George
foxy怎么用Fischer offers a wide lection of materi-
als, sizes, and scales. All types of end
connectors are available.
Limit Switches
Minimum and maximum limit switches
can be easily installed and adjusted
using the integral mounting rail. The
reed switches provide an accurate flow
readout when activated by the optional
magnetic float.
Mode of Operation
The weighted float is raid by the fluid flowing upwards through the tapered tube. The float is raid to the point at which the lifting force is in equilibrium with the weight of the float. The level to which the float is raid is determined by the rate of flow of the fluid.
