Wireless technology can provide monitoring and protection in remote locations.
An evolution in pressure-sensing technologies and the standards that regulate them help prevent equipment failure.
New equipment improves SCADA functions.
Pump monitoring instrumentation is often not included with installations, but proper sensors can protect a pump and help with efficient operation.

This article will define a business case for achieving significant rotating equipment maintenance and energy cost reduction at industrial and municipal facilities.

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.

Soft foot is one of the most prevalent conditions found in rotating machinery. This condition, if not corrected, makes an alignment job much more difficult and sometimes impossible. If the internal alignment is not correct, the external alignment will not matter.

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.

When it comes to pressure and flow, variable speed pumping applications can be divided into three basic categories. Constant pressure-variable flow (Cp-Vf) attempts to keep pressure relatively constant over a range of flows. Constant flow-variable pressure (Cf-Vp) tries to achieve the opposite by using varying pressure to keep flow constant. Variable pressure-variable flow (Vp-Vf) applications can accommodate a change in both.

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.

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.
