Increased efficiency, higher air handling and fast, automatic priming are provided with new technology.

Dynamic pressure sensors and accelerometers are frequently used for precision measurements in oil, gas and petrochemical industries, as well as for natural gas supply monitoring applications. The development of piezoelectric sensor technology with integral charge amplifier, as well as the development of high temperature charge output designs, has been especially important for dynamic sensing applications. To truly understand the benefits of this technology, one must first review the evolution of this type of sensing.

While scheduled downtime is different from unscheduled, both can take away from a company.

Questions are answered about monitoring power consumption and noise level parameters for pumps.

An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

Explore best practices for securing SCADA systems in remote sites. This article addresses threats and corresponding implementation measures with a focus on SCADA RTU installations and the processes they monitor and control.

In today's growing industrialized market, the need for reciprocating pumps is increasing daily. As technology drives modernization, the demand placed on the pumping systems is continually rising.

Yuba County Water Agency in Marysville, Calif., recently chose a wireless system as a solution for a water pump problem. Here are some of benefits they discovered.

The past may be prologue to the future, but the time between the two seems increasingly short. In the past, labor, capital and raw materials were considered the underpinnings of wealth creation. Today, real-time process knowledge and innovative management strategies have become far more important for creating value, as evident in the headlines above. Accordingly, the time for systemic change is now. . . the opportunity to reinvent industrial manufacturing and the products and services that surround it have never been greater since the beginning of the industrial revolution.

Beating occurs when two dynamic excitation sources (forces) are close together in frequency, and a pathway allows the two excitation forces to transfer to each other. The beating effect results because the frequencies are so close to each other that the waveforms alternately reinforce each other at some times and cancel each other at other times. When the vibration from each source adds constructively, the vibration increases. When the vibration adds destructively, the vibration decreases.

VFDs replace mechanical devices and PLCs for lead-lag pump control.

Any time a measuring instrument is used in a plant, it is expected to provide reliable results.

Electric drives are used in various applications in the oil and gas industry for varying motor speeds driving critical components, including pumps, fans and compressors.

Wireless control and monitoring are a vital part of pump systems.

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.

The 4-20mA current loop is used to transmit analog data representing various process variables like level, pressure, temperature or flow. Although conceptually simple, a 4-20mA current loop can be tricky to troubleshoot. Current flows in a single direction through each device in the loop.

The residents of Orlando and nearby communities are more likely to see lightning strike than have their toilets run dry. Extensive high-tech upgrades at Orlando's three advanced wastewater treatment plants, including new automation and control systems, have helped city staff process more sewage and gray water effectively and reliably.

Pressure gauges are an important indicator of whether a system or component is operating correctly. Pressure gauges generally require little to no maintenance, other than periodic calibration. However, if gauges require minimal maintenance, why do some seem to continually wear out?

A successful infrared program involves planning and action. This article outlines steps that will help you implement a thermography program.
