Air flow pressure switches and differential pressure switches work just like the light switches we have in our living rooms at home: when they are switched on, the switch makes contact, closes the circuit, and turns on. When they are switched off, the circuit is broken and power turns off. With air flow switches, instead...

There are a wide variety of technologies that can be used for fluid flow measurement, such as differential pressure, paddlewheel, electromagnetic, and ultrasonic. Furthermore, each technology has multiple installation configurations. It is important to understand the nuances of different technologies and installations in order to pick the right flowmeter for your application. When purchasing a...

Maintaining efficiency in wet chemical scrubbers has become one of the most important missions of current APC facilities due to urban growth and plant expansion/modernization projects as good stewards of the community. Systems often run above the 90% efficiency mark with the help of accurate make-up water control instruments. One of the most important components...

Room pressure monitors are devices that monitor differential pressure between two rooms or areas. Differential pressure is the difference of two pressures being sensed. There are several applications where it is important to maintain a pressure difference between two rooms. This helps to ensure that there are no contaminants entering or exiting a protected area. In a medical setting,...

The Series SAH SMART Air Hood® balancing instrument looks different than traditional air hoods, but that’s because it’s solving balancers’ problems in a new way. Take, for example, some feedback we received from Ken (a TAB technician) earlier this year. Small, highly maneuverable air hoodKen was measuring standard 2’ x 2’ diffusers with our SMART Air Hood®...
