Model 460 Air Meter/Draft Gage

Series 100 AV Durablock® Air Velocity Gage Kit

Suitable for Total Pressures to 100 psig (6.89 bar), Temperatures to 150°F (65.6°C)

Designed to measure air velocity, static pressure, vacuum or differential pressure, where the additional range of the 400 Series gages is not required. Series 100 Gages offer superb accuracy combined with portability. The Dwyer® Durablock® precision machined solid acrylic plastic construction, the wells and inclined bore are machined to tolerances of ±.0002".

Complete Air Velocity Kits Include:
Dwyer® Inclined Manometer, stainless steel Pitot tube (12" with Models 102 AV & 115 AV), two 9' lengths of rubber tubing with connectors, additional red gage fluid, instruction card H-7, Bulletin H-11 and magnetic mounting clips, air velocity calculator slide rule and carrying case.

Features

  • Plastic Body - A 1" thick solid acrylic block, virtually unbreakable. It is stable and free of the danger of distortion.
  • Drilled Bore - Permanently free of bends - never requires recalibration due to distortion.
  • Reflective Chrome Finish Scales - Easily eliminates parallax errors in reading. Adjustable, with thumbscrew locking for easy zeroing. (Model 125 AV uses screw plunger to adjust zero setting).
  • Red Gage Fluid - .826 specific gravity. Forms a well-shaped, easy-to-read meniscus - the result of high wetability.
  • Leveling Adjustment - Screw allows quick, accurate leveling. Integral ground glass bubble level provides ready reference.

Questions

Question
What are the principle advantages of red gage fluid over water for use in manometers?
Answer
Red gage fluid is slow to evaporate, won't freeze, is more readable and produces slightly expanded scales for better reading resolution.
Question
Is routine maintenance required for a Dwyer red gage fluid type manometer?
Answer
Yes. The zero point should be checked periodically as well as the fluid level. After a year of service, particularly with dirty air, the fluid should be replaced to assure that specific gravity changes are not affecting the accuracy of the reading.
