In the 21st Century, remote monitoring is easier than ever; but it is more than simply wireless communication.<br /> <br /> Increasingly, municipal wastewater companies, water supply operators and farmers are discovering the benefits of remote monitoring, but not all take advantage of the advanced management possibilities offered. Some companies offer a range of communication components and total solutions that save time and costs – and, more importantly, address the real concerns operators have about remote management.<br /> <br /> One is the need to make best use of limited resources. With pumping installations spread all over the countryside, onsite inspection is simply a poor use of time. With a wireless telemetric system, monitoring and control tasks can be performed from a PC anywhere anytime. When a pressure drops, a pump blocks, or a flow decreases, those wirelessly connected are the first to know. As equipment succumbs to wear and tear, they have time to plan maintenance. As renovation projects draw near, they can draw on By Helen Mubarak hard facts to make decisions.<br /> <br /> Online monitoring<br /> <br /> One company that helps connect the user to their machinery is Grundfos, based in Denmark. The company developed the software system in house. This reduces interface issues and ensures that each component is developed with pump installations in mind.<br /> <br /> The remote system is an Internetbased telemetric system that provides operators with timely information, allowing them to keep their wastewater and water supply systems operating cost-effectively. System managers only need Internet access, a standard browser and a password to monitor and manage their pump installations. The software sits on the company’s own corporate hosting center, which saves customers the cost of hosting, servicing and maintaining both software and hardware.<br /> <br /> Remote monitoring provides users with an overview of all the many pump installations in their system. Users can upload a map or their own photos, and drag-and-drop installations to their location. The start-up screen displays if there is a problem, what the problem is and the location of the affected installation. Then, users are able to dive deep into the details.<br /> <br /> Mobile monitoring<br /> <br /> When an alarm occurs or a value triggers a warning limit, the system will send an alarm SMS or email to a designated mobile phone or computer. Managers can plan on-call schedules months in advance. The schedule determines who is to receive alarms at any given time of the day or night, year round. And those receiving the message can log on to the system and determine the course of action to be taken from a PC, a Smartphone and/or a Tablet PC from anywhere in the world.<br /> <br /> Trends and reports<br /> <br /> Changes in pump performance can easily be tracked using trend graphs that are automatically generated. Service and maintenance can then be planned based on the actual conditions. Timely service and maintenance has a direct and positive impact on the system energy consumption and operating costs.<br /> <br /> Different remote monitoring modem variants allows connection to e-pumps, controllers, VFD’s as well as third party pumps, sensors, alarm contacts, switches etc., and to the remote monitoring system and also enables wireless data communication. That allows the monitoring tank levels, pressure gauges, sensor values and pump condition and accessories.<br /> <br /> Helen Mubarak is a communications officer for Grundfos.
