Mechanical pressure gauges, which require no external power, provide an affordable and reliable source of accurate pressure measurement. Using the criteria below can help maximize gauge life.

Low-cost additions help bottle maker manage compressed air use and energy costs on a shoestring.

Many items must be considered when designing pump station control systems with power requirements, level control method and control panel location often among the most important.

Third in a series. Advances in wireless technologies can help address many common failure modes in mid- to low-level criticality assets and eliminate wiring costs for a range of asset types.

Although the use of transmitters in pressure measurement is growing, mechanical pressure gauges are still used on most systems as local pressure display to back up electrical readings. The selection and installation of these gauges can be difficult in certain locations. Harsh conditions that can require special consideration include vibration, pressure pulsation, overpressure, corrosive media and extreme process and ambient temperatures. This article is designed to address harsh conditions with best practice recommendations to extend gauge life and provide for the safest installation possible.

You have probably noticed that there are several camps out there when it comes to centrifugal pump applications involving variable frequency drives (VFDs). One group believes that every pump should have one, while another thinks that they should be banned altogether. And, of course, there is the middle ground that says it depends upon the pump and application. pump system optimization, pump efficiency

Of the technologies available for condition monitoring of rotating equipment, the quickest return on investment is from vibration analysis. For the novice, vibration data seems complex and is generally difficult to assess compared to other techniques. Once trained, however, the novice can recognize the patterns and diagnose a machine problem.

Monitoring vibration—a valuable tool in predictive/preventive maintenance programs

An 1,800 MW power station in the Midwest experienced constant trouble with four of its four-stage boiler feed pumps, which were driven by steam turbines and operated at variable speed to meet the required plant load.

Find the right flow meter for your process and plant.

PWM inverters introduce motor shaft voltages and bearing currents. The bearing damage in inverter-driven motors is mainly caused by the shaft voltage and bearing currents created by the common-mode voltage and its sharp edges [1]. All inverters generate common-mode voltages relative to the power source ground that cause coupling currents through the parasitic capacitances inside the motor. The main source of bearing currents is the capacitance-coupling currents that return via the motor bearings back to the ground.

As a public water provider, Loudon Water, a water and wastewater authority in Loudon, Va., must be able to supply water to meet the community's needs.

A dangerous misconception exists regarding the "Arc Rating" of infrared (IR) windows or viewing panes. Many reliability and maintenance professionals are under the impression that an IR window will protect them in the event of an arc blast. Others believe that installing IR windows will turn non-arc-rated switchgear or electrical equipment into "arc-rated" cabinets. Neither is true. Both misconceptions need to be corrected because they present safety concerns.

In the last decade, ultrasonic flowmeters have grown in popularity in laboratory and process areas as a cost-effective, noninvasive alternative for measuring the velocity and flow rates of liquids and gases.

Your company has recently purchased a laser based alignment system. Your newly trained technicians are asked to align a critical process pump. You witness the alignment. They save the final alignment data. You review the data, but what does it mean? How does it compare to dial indicators? Why did they rotate both shafts when measuring the misalignment? Why are the numbers at the feet higher than you would like? How do you KNOW the alignment is good? The debate begins.

"An ounce of prevention is worth a pound of cure" may have been coined by process and plant engineers tired of repairing or replacing pumps. Pumps are often the most under-serviced pieces of equipment in process automation when it comes to maintenance and prevention best practices. Unfortunately, nothing moves without the humble pump, and a process becomes inefficient when a pump doesn't operate properly or completely shuts down. Many times the pump manufacturer is seen to be the problem, when in fact the process or the surrounding equipment configuration is the cause.

Why question the PLC? For many, questioning the application of a PLC to the pump station panel is surprising. After all, the pump station panel was once controlled with a range of relays, timers, and other devices - the exact type of application where the PLC has had such success in industrial automation. pump efficiency

It required only a couple notes of the haunting soundtrack to signal an imminent shark attack in the movie Jaws. As the theme began to swell, it became obvious that someone was going to “get it.” It would be nice to have a sixth sense that allowed us to hear "warning" music in daily situations. Condition monitoring systems provide a means of sensing when sharks are skulking toward your critical machines.

Pressure gauges are a versatile way to monitor pump operation.

In the past, the nuclear power industry has experienced equipment failures due to improperly set oilers. There was never a precision tool available to help ensure the level was being properly set on a typical oiler . . . until now.
