Extreme Cold and Pressure Sensor Protection 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. Often times — especially at Water Towers — the pressure transducer is protected from freezing via installation in a … 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 →
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 →
