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.

Question

What is the best method of measuring actual air flow in process ducts to verify process air flow sensors (differential pressure sensors, air flow stations, etc.)

Answer

There are two ways to measure air flow in process ducts. The most common means is the use of a Series 2000 Magnehelic® Differential Pressure Gage. This gage can be ordered with a square root output that will read in flow units. You will have to specify the maximum differential pressure at your desired flow rate. Along with the gage, a pitot tube (connected by means of rubber or vinyl tubing) is also used. The pitot tube must be pointed directly into the air stream. Care must be taken to ensure that the pitot tube should be inserted at least 8-1/2 duct diameters downstream from elbows, bends or other obstructions which cause turbulence. The alternative method uses a 100 AV Durablock® Air Velocity Gage kit. The kit includes a manometer, a stainless steel pitot tube, rubber tubing with connectors, and red gage fluid. The pitot tube, pointed directly into the air stream, senses total and static pressure. The manometer then senses velocity pressure (difference between total and static pressure).
