Instrumentation

Latest Instrumentation Articles

In complex systems, many factors can affect overall performance.

My previous two columns have described assessing a system that does not use controls. In the first part (Pumps & Systems, October 2014) the assessment process was detailed.

In Texas, the hot, dry summers make water use and conservation a top priority.

Power generation plants face difficulty when conserving water, regardless of size or fuel source.

With easy access to electricity, electric motors are now an option for large pumps and compressors once powered by gas engines or turbines.

Who determines where pressure gauges are located in a pump system? How close to the pump should they be, and what happens if these rules are not followed?

Approximately 75,000 gallons of water are required to produce 1 ton of steel. Water transfers heat, removes scale from steel and converts gases produced in ovens and furnaces.

Rural wastewater utilities rarely, if ever, consider upgrading to an automated control system.

In today’s industrial facilities, using reliability-centered maintenance as the primary approach to reduce maintenance costs and operational downtime is more commonplace.

Most engineers would say that the International Society of Automation (ISA) 100 standard covers wireless instrumentation in process plants.

For those of you old enough to remember Lawrence Welk, you’ll notice that the title of this brief column is the final quote from his show’s closing song. I am still a loyal fan of his reruns today.

Last year, “Reduce Thrust and Extend Bearing Life” (Pumps & Systems, December 2013) discussed the benefits and some potential pitfalls of adjusting the axial clearance of American National Standards Ins

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.

Abundant oil supplies from U.S. shale producers may have upset global markets in recent months, but one resource may present even more of a challenge to the international community in 2015—clean water. Demand has clearly outstripped supply in some of the world’s most arid regions.

My previous two columns have described assessing a system that does not use controls. In the first part (Pumps & Systems, October 2014) the assessment process was detailed. Last month, I covered performing the system calculations (Pumps & Systems, November 2014).
