PTBnews 2.2023 A method for calculating the simulation uncertainty of a virtual ultrasonic flowmeter has been developed in PTB’s VirtMet Competence Center. This method allows calibration factors relevant to fluid mechanics to be calculated for […]
Following a successful bid for £950,000 funding from Horizon Europe, TÜV SÜD National Engineering Laboratory will build the first UK national standard liquid / dense phase CO2 calibration facility. The 3.5-year project, called “A European […]
The XPR105MCP is the high-speed solution for ISO 8655-compliant calibration of multichannel pipettes. It has a readability of 10 μg and supports multichannel pipettes with up to 12 channels and nominal volumes from 0.5 – […]
Researchers at NIST have developed a new — and sound — way to accurately measure the rate at which gas flows in and out of a vessel. The technique, which uses acoustic waves to determine […]
