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.

In the U.S. industrial sector, motor-driven systems consume 70 percent of all electricity. Motor-driven pumps account for more than 30 percent of that amount-more than any other application. Considering energy and maintenance represent more than 80 percent of total motor life cycle costs, a growing number of system designers, specifying engineers, maintenance professionals and end users are turning to variable speed motor control systems that can save up to 60 percent in energy costs as well as significantly reduce maintenance and equipment costs, improve process control and enhance system reliability.

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.

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.

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

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.

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.

Last month we reviewed the pump selection criteria for a typical constant pressure-variable flow (Cp-Vf) application that utilized variable speed (VFD) control. This month we will explore an application where pressure varies in proportion to a change in flow.

Read how WirelessHART can be implemented in large process plants despite the distances needed for the network.

As oil prices and gasoline usage have increased, the demands on U.S. oil and gas wells have grown dramatically. In the past, there was a low cost supply from the Middle East, and U.S. oil wells were not used as frequently due to low reservoirs and the energy cost associated with extracting the oil. A large number of U.S. wells were shut down in reaction to high electric costs, low oil prices, the need for monitoring the oil reservoir and machine maintenance. As of 2004, there were just over 800,000 onshore oil wells in the world, with about two-thirds of them in the United States.

State and federal requirements increase the need for pump monitoring and control.

The Village of Mundelein, Ill., 35 miles northwest of Chicago, had a growing water demand and needed options for managing the increasing demand.

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.
