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 →

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 →

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 →

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 →
