manometers measure positive,negative & differential pressures.
-Dwyer Flex-Tube U-Tube Manometers combine the inherent accuracy
of the simple "U" Tube with the durability
of tough, long-lasting plastic construction.
-Columns are of .375" O.D. flexible and shatter proof clear
-They are easily accessible for cleaning. Indicating tube is backed
by white scale channel to provide maximum color contrast.
-Scales are extruded high impact polystyrene plastic, formed to
hold columns in perfect alignment.
-Stark white scales have graduations and numbers silk screen-printed
in black for maximum legibility.
-You can choose from
numerous models and features including over-pressure safety
traps, in full scale ranges from 8" to 36" of water or
-All are suitable for total pressures to 100 psi - for determining
velocity and static pressures, leakage, fan and blower
efficiency, filter resistance, and gas pressures. -Ideal wherever
a portable, direct reading manometer is needed.
-Standard ranges and markings as shown, or special ranges,
colors, logos and brand names for OEM quantity
orders are available.
Minor Divisions of 1/10" water column (or 2mm water column on metric
units) are silk screened in jet black on stark white scale for positive
definition. Easy to read, even at a distance, they are acrylic coated
for permanence. All models are furnished with one ?ounce bottle
of fluorescien green color concentrate with special wetting agent
for W/M models, or ?ounce bottle of red gage oil for "D"
simplest, lowest cost basic U-gage. A dependable U-tube manometer
that withstands hard use and provides accurate, high visibility
readings. For use with water, mercury or red gage oil. For mercury
filled manometers, a scale clamp bar, Dwyer Part No. A-363 (available
as an extra for Series 1221 - and standard on Series 1222) is recommended.
Pair of carrying plugs and a pair of non-kink vinyl tube connectors
included with each manometer.
Series 1222 Manometer, All the features of the 1221 plus magnetic clips for
mounting to any vertical steel surface, and clamp bar to insure
against U-tube slipping. (Especially recommended for manometers
used with mercury.) Both magnets are easily removed and replaced
at the user's convenience.
Series 1223 Manometer, Our finest U-gage - for either portable or stationary
use. Safety traps prevent loss of indicating fluid in case of accidental
over-pressure. Tubing is permanently bonded to a molded, high impact
acrylic plastic top that contains safety traps. Large magnetic clips
and clamp bar are provided. Standard type "a" connections
include two rapid shut-off type molded nylon tubing connections,
two 3' lengths of flexible Tygon plastic tubing, and two 1/8"
pipe thread to tube adapters.
Over-Pressure Safety Traps are
featured on Dwyer Series 1223 U-tube manometers. The
actions is simple but positive. Over-pressures, whether
gradual or a sudden surge, simply raise the cork and
seal the fluid in the gage. When pressure drops, trap
opens and gage resumes operation.

How To Order:
1. Indicate series
such as 1222.
2. Indicate range
desired such as : 8, 12 or M200.
3. -Specify "W/M"
with model number for inches* of water , using water or inches*
of mercury, using mercury.
-Specify "D" with model number
for inches* of water using .826 sp. gr. red gage oil.
-Red gage oil is often preferred for readings
in inches of water because of the longer scale and
slower evaporation rate.
-This lessens the need for frequent re-zeroing
(If not otherwise indicate,
"W/M" style manometers will be shipped.)
4. For Series
1223 only, state the connection option desired if other than standard
For example, 1223-12-D-"b" manometer
is a Series 1223, range 12" w.c. (scale 6-0-6), using red
gage oil with type "b" connections.
