Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
Threaded connections are often referred to as a process connection type. For Dwyer product specifications, this connection type is typically NPT (National Pipe Thread), which is an American standard thread. These connections allow products to be installed directly into piping or with the use of threaded fittings.
For threaded connections there are two common types, (1) straight or parallel thread and (2) tapered thread. Continue reading “U.S. and International Threaded Connection Standards”

For personal vehicles, many designers turn to enclosed parking garages to fit as many vehicles in as small a space as possible, or to mixed-use structures that combine a parking garage with work or living space in one building. For commercial traffic, loading dock operators are designing docks and material handling systems to service shipping vehicles as quickly as possible.

Many people think that we get cold and flu viruses more often in the winter due to the cold temperatures outside; however, this can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
