Inclined Manometers
 

No. 424-10 Inclined-Vertical Manometer, 0-10" water range. The inset shows a segment of the inclined scale. No. 424-5, 0-5" water range is similar.

Typical of Series 420 Inclined-Vertical Manometers is this No. 422-10 double column manometer with a total range of 0 to 10" of water. Single column models are also furnished. Design features are essentially the same as for the Series 424. They are accurate to ±1% and are particularly suited for use with pitot tubes and in flow measurement or similar applications.

 

 

 

Dwyer® No. 424 inclined-vertical manometer are extremely accurate instruments designed and made especially for precision measurement of low differential pressures in laboratory and test applications. The inclined range bore has a length of 20" to provide ample multiplication of indicating fluid movement in this critical lower part of the range.

STANDARD ACCESSORIES
Includes two 3/4 oz. bottles of .826 red gage oil (1.91 blue gage oil for models 421-23 and 422-23), rapid shut-off type "a" connections, two 3 ft lengths of clear plastic tubing and two 1/8" NPT tubing adapters - two sets for double column models.

  • 3/16" BORES, ACCURATE TO ± .0002"
    are permanently free of bends or crooks, will not require recalibration because of distortion.
  • GROUND GLASS BUBBLE LEVEL
    sensitive to 115-125 sec./2 mm. is 1-1/2" long x .375" diameter and provided with two red lines for easy visibility and alignment.
  • PARALLAX-FREE READING
    for maximum accuracy and consistency is achieved by simply aligning the meniscus with its image reflected in the polished aluminum scale.
