Series 1227 Dual Range Flex-Tube® U-Inclined Manometer
0.2" Minor Scale Divisions, Accuracy +/- 0.1" W.C.
The Series 1227 Dual Range Flex-Tube® U-Inclined Manometers are versatile, low cost manometers that can be used to read high-range pressure on the right leg or as an inclined manometer to read low-range pressure on the bottom leg. It is made of a sturdy, clear plastic and offers direct readings as a U-tube or an inclined gage. Magnetic clips are attached to the unit to hold it in position on any steel duct surface and instructions are conveniently printed directly on the scale.

- What are the principle advantages of red gage fluid over water for use in manometers?
- Red gage fluid is slow to evaporate, won't freeze, is more readable and produces slightly expanded scales for better reading resolution.
- Is routine maintenance required for a Dwyer red gage fluid type manometer?
- 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.
- Will the water manometers freeze?
- Yes, if the temperature drops below 32 degrees Fahrenheit, the fluid in the manometer will freeze. The fluid used in "W/M" style manometers is water-based with a small amount of fluorescent green fluid to enhance the meniscus. The other gage fluids have a lower freezing point, however, it is recommended that the manometers be stored above 32 degrees Fahrenheit.
