Navionics Research Inc. is pleased to introduce a MODBUS/TCP and MODBUS/UDP CLIENT feature for its SCADA Server Software system! Has your Water Utility ever had the need to monitor Office and Plant Infrastructure, such as Power, Generator Status, Physical Security (Entry & Motion Detection), Office Temperatures, Utility Consumption (Water, Gas, Electricity Meters), and Water Salesmen.  If Read More →

At custody transfer stations — and pumping stations in general — it is often necessary to supplement the level of disinfectant in the potable water. The purpose of this article is to discuss an effective and efficient technique that Navionics Research has developed that offers the following key features: Influent Flow Disinfectant Level Monitoring Disinfectant Pump Speed Read More →

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 →

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 →

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 →

A topic of immense concern to Levee Districts is the tracking of pump flow rate (e.g.. gallons per minute), as well as the totalization of pumped volume (e.g.. total gallons, cubic feet, or acre-feet). Flow-rate is important, as the Districts are able to trend instantaneous pump performance in real-time, which provides a measure of the Read More →
