Edwards High Vacuum has introduced the GV Drystar range of dry running vacuum pumps. With no oil in the pump mechanism, they provide clean and cost-effective pumping.
They can be used in hard disk manufacture to reduce contamination caused by dust and oil from conventional vacuum pumps. The vacuum pumps are available in a range of sizes either separately or within the company’s hydrokinetic drive mechanical boosters.

Transport PT868-R from Panametrics is a portable flowmeter available with transflection mode and transit-time mode.
Users can now measure fluids from ultra-pure water to slurries, and pipe-wall thickness using the optional thickness transducer, with one ultrasonic instrument.
The device can also measure energy flow using inputs from temperature transducers.
It uses high-speed digital signal processing techniques, including patented acoustic signal coding and correlation to yield high signal-to-noise ratios in the most demanding applications.
