RTU Enclosures Can Trap Heat During Summer Months During the summer months, the internal air temperature of outdoor-installed RTU Enclosures can become very hot — especially at locations where the enclosure is subject to direct sunlight.  And while the RTU electronics are industrial-rated, and designed to withstand extreme temperatures, the longevity of the equipment can be Read More →

When NRI’s VFD & Energy Analytics is implemented in a water plant or pumping station, VFD (Variable Frequency Drive) fault alarms are passed as numerical codes to the SCADA system via an industrial communication protocol (e.g. Modbus, DF1, EtherNet/IP, etc.) and then to the operator. A code of ‘0’ (zero) signifies no fault condition, whereas a non-zero code signifies that a fault Read More →

In rural areas — due to a combination of long power transmission line lengths and the relative isolation of the remote pumping facilities — it is not uncommon for stations to suffer from power quality problems.  Therefore, it is always recommended that a station’s power status be monitored, trended, and alarmed for outages. In the most basic sense, Read More →

In the Rural Water Industry, when a pressure or flow regulation valve is needed, the traditional choice for many years had been the diaphragm-type valve.  In 2002, however, we introduced a new and improved flow and pressure regulating valve/telemetry technology: the electronically-controlled, high-performance butterfly valve. The High-Performance Butterfly Valve offered many advantages over the diaphragm valve, especially in Read More →

I am very appreciative of all the positive feedback that I’ve received over the past few days as a result of this 3-part series of articles: Part 1, Part 2, Part 3.  I am glad that I was able to convey how the latest VFD technology — when leveraged to its full capability and coupled tightly with our new VFD & Energy Analytics Telemetry Software — is Read More →

Yesterday, in Part 1 of this series, we reported that a recent pump station upgrade resulted in a staggering energy cost reduction — reducing the average electricity charges from $345/month to less than $114/month!  Since you have kindly returned today for Part 2, your consideration will be repaid with the details of how this feat was accomplished — and how Read More →

A topic of continual concern for today’s water utility is Pumping Station Energy Efficiency. And to put this subject in laymen’s terms, how better than to relate it to fuel efficiency for the familiar automobile?    First, let’s look at the work that each produces — With a car, the unit of work is expressed as a driven “Mile”; whereas in Read More →

Extreme Cold and Pressure Sensors During extremely cold temperatures, it is important to keep in mind that the pressure sensing devices in your system — and the tubing that feeds them — should be prevented from freezing.  These devices include pressure transducers, pressure switches, and pressure gauges. If the water in the sensor or sensing line freezes, the expanding Read More →

One of the most compelling features of the Navionics Research SCADA System is its robust remote access capability — it’s ability to connect the Water Operator with the SCADA System so that he/she may check on the status of the water treatment and distribution system, review alarms, and make operational adjustments.  The dawn of the Smart Phones Read More →

The Sensaphone Model 400 is a telephone alarm dialer device that is capable of calling out (with a computer-generated voice) to one or more (up to four) telephone numbers to annunciate an alarm condition, as signaled by discrete contact inputs. The Model 400 features four (4) input channels, plus integral power monitoring. Channel #1 is pre-configured by default Read More →
