Use pulse radar to give level measurement the silent treatment
ABM pulse radar units are designed for liquid-level measurement at distances of 33 ft, 50 ft and 100 ft from the target. This system works by analyzing the shapes of the received echoes — eliminating the ones coming from tanks’ walls, standpipes and other obstructions — and makes very little during operation. This quietness is achieved by automatic adjustment of the pulse amplitude and width to a target distance, the reflection properties of the target, and the sensitivity of the receiver to returned echoes. Typical applications include detection of a water-oil interface and measurement of the thickness of an oil layer. Product or material build-up on the rod or horn antennas will not deteriorate the performance of the radar, says the vendor. — ABM Sensor Technology, Peterborough, Ontario, Canada

Compact solution to the difficult problem of dry vacuum pumping
The IDP-3 dry scroll pump brings the proven benefits of dry scroll technology (that is, minimizing the possibility of seizing or sudden loss of vacuum) to applications where vacuum performance and environmental concerns are critical. The motor and bearings are located outside the vacuum space, allowing full isolation of all pumped gases. The benefits of this design include: lower noise and vibration levels, long-term reliability and simple maintenance requirements. The IDP-3 measures 14 x 7 x 6 in. dimensionally. But despite its small size, it delivers a pumping speed of up to 60 L/min, while maintaining a base pressure of less than 250 mTorr — almost four times lower than that of an equivalently sized membrane-diaphragm pump. In turbo-pump applications, lower base pressures reduce the power consumption and bearing temperatures, which results in improved reliability of the vacuum system performance. —Varian, Inc., Lexington, Mass.
Catalyst vacuum’s repeatability is not reproducible by human hands
OutageMaster II is a computer-controlled multi-tubular vacuum-to-outage device that automatically removes the desired amount of catalyst from multiple catalyst-packed tubes, and is said to do so in half the time required by manual methods. This patent-pending system is so carefully controlled that the repeatability of its results cannot be reproduced by laborers using a hose. The technology works on any size tube for a critical task in the catalyst-loading process. In addition, because the fragile catalyst pellets removed are very expensive, OutageMaster II ensures that the catalyst is not damaged in the process. Pellets are reloaded into the remaining tubes with minimal breakage and waste, saving both time and money. — TubeMaster, Inc., Louisville, Ky.
