This new line of test kits measures flows in hydraulic and pneumatic systems. "We used to have a barrel-shaped scale that the user read as it moved with the cylinder," says Rich Little, the chief mechanical engineer at Hedland Flow Meters. "You could get different readings depending on how you looked at it," he says. The new flow meters have scales that are easier to read because they are fixed and have larger viewing areas. "We also improved the accuracy of the meters to±2% by tightening up our spring specifications and improving the tolerances in our cylinder pistons," says Little.
The hydraulic test kits measure pressure up to 6,000 psi at flows up to 150 gpm. Pneumatic kits measure pressures up to 600 psi at flows up to 1,000 scfm. All kits install in any position and do not require special piping or flow straighteners. Port sizes from¼to 1½inches are available in aluminum, stainless steel, and brass. In addition to verifying flow rates in trucking applications, the test kits also check pump and compressor performance, measure pressure drops, balance multi-line systems, and locate line restrictions in plastic injection molders, steel mills, and machine tools. The kits can be used as permanent monitoring devices and troubleshooting tools and are compatible with petroleum fluids, phosphate esters, water-based fluids, and compressed gases.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
