For higher flow measurements, Universal Flow Monitors Inc. added 3-inch and 4-inch pipe sizes to its family of CoolPoint vortex shedding flowmeters. The 3-inch unit has a maximum flow rate of 300 gpm (1,136 lpm) and the 4-inch unit has 600 gpm (2,271 lpm). The pipe connections are ANSI 150# RF flanges. For flow applications involving heat removal, an optional temperature transmitter adds the capability of monitoring temperature readings and transmitting them to a process controller.
The electronic units have a 4 to 20 mA and one switch or pulse outputs. Users' configurable features include: engineering units, selectable alarm state, set points or pulse out, and flow direction. Units with both flow and temperature outputs have standard flow output plus 4 to 20 mA and a set point for temperature. The flow alarm specification is 5 percent full-scale deadband, accuracy is ±2 percent full-scale, and repeatability is ±0.25 percent. For temperature, the alarm is ±2 percent full-scale deadband, with an accuracy ±1 percent full-scale, and repeatability of ±0.25 percent. Maximum operating pressure for either unit is 200 psig (13 bar).
The vortex shedding design has no moving parts, which eliminates the potential for jamming or coating. The units can measure and monitor flow in cooling loops using low-viscosity, clean or dirty water-like liquids compatible with brass, PVDF, and Viton. The flowmeters target measurements of cooling water, water/glycol coolant and low-viscosity fluids in automated and robotic machinery.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
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.
