Velocity Measurement and Environmental Effects

Differential pressure measurement can be beneficial in a wide variety of building automation system (BAS) applications.

One of these applications involves determining if a filter in your system needs to be cleaned or replaced. Filter health can be established by monitoring the pressure on the primary and secondary sides of a filter. A clean filter will typically have a baseline differential pressure generated as air flows through it. As the filter becomes dirty, this differential pressure increases.

When using a mechanical flow sensor, such as a pitot tube, differential pressure can also be used to determine flow velocity and volumetric flow. Continue reading “Velocity Measurement and Environmental Effects”

Why Choose the Original Equipment Manufacturer for Calibration Services?

You’re probably familiar with OEM products. But what about OEM calibration services?

OEM stands for Original Equipment Manufacturer and describes companies that make devices from component parts. Some OEMs also offer calibration services that are specific to the product you purchased from them. For many types of test equipment, annual calibration is necessary to ensure the measured values meet the original specifications. Sending your equipment back to the original manufacturer ensures the highest-quality calibration, giving you the confidence needed to effectively measure and test in your business.
