Water Utility Pumping Stations and Filtration Plants are heavily reliant upon the electric power grid, and therefore it is often desirable to closely monitor the quality of the incoming power.  As a general rule, NRI has always offered basic power fault tracking at all Telemetry-monitored stations.  However, at certain critical stations, it is desirable to Read More →

Altitude Valve Automation at Potable Water Districts Valve Automation serves a vital role in Potable Water Telemetry Control System Integration.  Valves are used in a variety of applications, which broadly include OPEN/CLOSE applications for ON/OFF flow control, as well as MODULATING applications for variable pressure and flow control.  This article will address an interesting ALTITUDE CONTROL problem Read More →

Historical Data Presentation is one of the primary functions of a SCADA System. Today, I am excited to introduce a significant upgrade that extends the usefulness of the History Database Module of your SCADA System! — a new, powerful Data Export Module that provides the Operator and his Civil Engineers with access to raw, time-stamped data. The exported Read More →

Navionics Research Inc. Is Pleased to Introduce a Premium Online/Double-Conversion Battery Backup System. NRI’s new online Uninterruptible Power Supply (UPS) with LCD control panel and sine wave output is offered as a power safeguard for SCADA Servers, RTU’s, and any communication/networking hardware that requires seamless power correction. Traditional (Standby) UPS Technology:  In a traditional (standby) UPS, Read More →

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 →

PC-Based Water & Wastewater Telemetry Solves Early-Obsolescence Challenge Since 1995, Navionics Research Inc. has based its Telemetry & Control RTU system upon an industrial-hardened PC architecture, which is arguably the most stable hardware standard in electronics history.  With many competing source manufacturers, availability is anticipated for many years.  The design philosophy is based upon the idea 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 →
