Proving Flow Through Chillers

Water chillers are nothing new, with nearly an estimated 100,000 units operating in North America alone. Chillers are the cooling machines of choice to condition industrial, commercial, and institutional facilities. They are used to lower the temperatures of all kinds of equipment and processes such as: robotic machinery; semiconductors; injection and blow molding machines; welding equipment; die-casting and machine tooling; paper and cement processing; power supplies; power generation stations; compressed air and gas cooling systems; medical imaging machines; chemical, drug, food and beverage production; even simply to cool potable water to desirable levels. Whether for office comfort, keeping data server centers from overheating, or specialized industrial processes, water temperature control plays a vital role in many of the behind-the-scenes activities that affect our everyday lives.

How to Program a Switch for Manual Reset

Compact Low Differential Pressure Switch with Manual Reset, Series 1900MR

Several applications require manual reset switches, which are switches that need to be physically reset by an individual for a process to continue or restart. A manual reset is often needed when an area has to be inspected prior to equipment restart. This can help to ensure the safety/inspection of both equipment and other individuals in the area.

Some switches have a mechanical manual reset (such as the Dwyer Series 1900, 1831, and 1800). However, there may be a need to have a manual reset for applications beyond what these switches are designed for. If a pump is allowed to run with a clogged filter, for example, this may severely damage the pump. Continue reading “How to Program a Switch for Manual Reset”

Monitoring Air Flow of Hydrogen and Methane Gases

A system integrator in California recently needed to monitor air flow of hydrogen and methane gas, requiring threaded connections to a steel line that the gases flowed through, as well as from the flow sensing device to the transmitter reading flow for their system controller. Hydrogen and methane are difficult gases to deal with, requiring a robust solution to monitor flow through the exhaust line without potentially posing a hazard.  Continue reading “Monitoring Air Flow of Hydrogen and Methane Gases”
