A key component installed within the control panel at all stations is a UPS (Uninterruptible Power Supply). In case of power outage, the UPS provides reserve power to keep the control equipment running until power is restored or until the battery depletes — whichever occurs first. NRI’s preferred UPS for water towers and small pump/lift … 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 →
Ice Storm Preparations When meteorologists are predicting an imminent Winter Ice Storm, it is highly recommended that the Water Utility perform certain preparations to minimize the potential impact to the production and distribution system. Freezing rain and Ice Buildup on Antennas can cause temporary loss of radio telemetry communications. So it is highly recommended that … Read More →
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 problem that we recently … 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 →
