The velocity of an air stream in a duct is not uniform over the cross section of the duct. This is because friction against duct walls causes the air velocity to be lower near the sides than the velocity in the center, creating a parabolic velocity profile.

Many Dwyer Instruments, Inc. products sense and measure pressure. This includes: gages, manometers, transmitters and switches.
Pressure is the amount of force acting on a specific area and is equal to the force divided by the area.
There are many types of pressure that are used and measured, including: atmospheric, absolute, gage, vacuum, differential and hydrostatic. Continue reading “What is Pressure and How is it Referenced?”
While summer is vacation time for most, it was the busiest time of year for the Dwyer marketing staff as we prepared for the launch of the 2018 Dwyer™ Catalog.
Many of your favorite products have been updated with new features, such as the addition of a High Accuracy version of our Magnehelic® Differential Pressure Gage; new lower ranges and an NPT process connection for our 616KD family of pressure transmitters; and new manifold valves for our Series 490A Hydronic Manometer.

California’s Proposition 65 (Prop 65), officially known as The Safe Drinking Water and Toxic Enforcement Act, is a California law that requires manufacturers to place a warning label on any product that the State of California has found to cause cancer, birth defects, or other reproductive harm. This law was initially enacted in 1986 to assist Californians with making informed decisions on the products they were purchasing which might impact their drinking water. Since then the law has been extended to include all routes of contact such as eating, drinking, touching, and inhaling. Prop 65 helps consumers stay informed with what chemicals they are in contact with. The basic premise required products to have warning labels; however, products can vary in their use, consumption and how they come in contact with people. For example, a Prop 65 warning may be listed on something simple like a food storage container in restaurant or a more complex product such as a pressure transmitter used to measure water pressure in a municipal drinking system.
