Measuring flow below atmospheric pressure can be challenging due to changing volumetric flow rates and pressure drop requirements. It is critical to consider operating conditions and device capabilities to ensure your flow meter gives correct readings. In this article, we will discuss the relationship between line pressure, flow rate, and pressure drop to determine the […]
Dr. Andrew Woods We head across the pond for a glimpse at the role Alicat plays in OEM products, courtesy of our UK distributor, Premier Control Technologies (PCT). A manufacturer of catalyst testing for aging equipment, Catagen Ltd plays a significant role in the worldwide reduction of automobile emissions. Its testing equipment relies on the […]
Cambridge CMOS Sensors (purchased by ams in 2016), is an industry leader in sensor technology. Their patented CMOS MEMS gas sensors use micro-hotplate technology to provide lower power consumption and faster response times for monitoring air quality and hazardous gases. Challenge: Testing CMOS sensors requires fast flow control flow for a wide range of testing […]
Validation, verification, and calibration all share the common goal of ensuring a process is working as intended. Here, we discuss these three interrelated but distinct processes and detail how to go about validating, verifying, or calibrating your system. At a basic level, the three terms may be defined as follows: Validation ensures a system satisfies […]
Founded in 1991 and headquartered in Roselle, Illinois, Graftel has emerged as the industry leader for nuclear facility leakage rate monitoring in the US. Regular monitoring both satisfies federal NRC regulations and serves as a preventative measure to help keep the working environment safe for power plant employees. From portable local leakage rate tests (LLRTs) […]
In 2011, Dr. Amanda Maxham established Flying Apple Space Technologies (FAST), a program that uses high-altitude ballooning (HAB) to inspire involvement in science, engineering, technology, and mathematics. FAST teams are encouraged to find creative solutions to the challenges associated with the launching of latex weather balloons into the atmosphere. Each balloon is fitted with scientific […]
