What is Pressure and How is it Referenced?
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?”

Explaining California’s Proposition 65
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.
Variable Area Flow Corrections
Dwyer Instruments, Inc. offers many flow measuring products including our very popular variable area flowmeters, often called rotameters. Dwyer manufactures variable area flowmeters in polycarbonate, the Series RM and LFM; in acrylic, the Series VF; and in glass, the Series VA and DR.
Variable area flowmeters have scales calibrated for specific media at specific conditions. Most commonly, the flowmeters are calibrated for air for gas use, and water for liquid use, at standard atmospheric conditions of 70 degrees Fahrenheit and 14.7 PSIA, which is 0 PSIG. When using the flowmeter in conditions other than these standards, the flow reading will not be accurate and corrections will need to be made. Continue reading “Variable Area Flow Corrections”
