Dwyer Instruments offers many electrical switch products that make or break a contact based on sensing a parameter such as pressure, temperature, level, and so on.
Most switches are single pole double throw, often referred to as SPDT. This type of switch has one normally open contact and one normally closed contact. Switches can also be double pole double throw, or DPDT, that have two normally open and two normally closed contacts. Single pole single throw switches with just one contact are also available and are specified to be either normally open or normally closed.

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.

The cleaning of produced water during oil and gas production and exploration is a crucial, although costly endeavor. In the process of bringing oil and gas up to the surface from a well, several byproducts are also produced. Water is the largest of these byproducts by volume, with 882 billion gallons produced per day. This produced water contains a variety of other compounds and substances, including organic and inorganic compounds, grease, bacteria, and dissolved solids such as iron.
