A circuit of the small inland waterways and canals with stops at the numerous quays is a so-called ‘must do’ for tourists as they say. For municipalities or canal authorities however, it is of great importance to have insight in the water level of these canals to prevent them from flooding. To gain more insight in the water level of the canals, the Ministry of Infrastructure uses sensors with RS232 protocols. Since this technology is quite an old-fashioned one, it is not suited for controlling the water level from several canals real-time from distance.

Fuel delivery has always had some built-in inefficiency. Like most fuel and lubricant distributors, Retif Oil & Fuel followed a keep full model when restocking fuel tanks and was spending too much money topping off customer fuel tanks and making emergency deliveries. Without an accurate view of customer fuel stocks it was impossible to determine who needed fuel or how much they actually needed.

Several Aerofiltri's products are used to measure the differential pressure on filters in air conditioning systems or for measuring air flow in ventilation ducts. A connected digital pressure gauge is needed to receive data collected in the field via web and identify pressure drop in the filters at the right time in order to prevent production delay and high maintenance costs.

Managing remote power generation sites has its own particular challenges, not least in terms of the efficient monitoring of operations. Given the nature of its power sources, many of the company’s power generation sites are located in remote and difficult terrain. This can present challenges in terms of the monitoring and control of remote locations.

Every year, spring rains and snowmelt pour into the rivers and reservoirs that feed the City of Calgary’s water supply. As a result, downtown businesses and residents are faced with unpredictable floods that could do millions of dollars of damage. The City of Calgary turned to the PI System for a data-driven approach to predicting and managing flooding.Both the Bow and Elbow rivers flow through Calgary’s borders and provide fresh water to the system. These rivers carry the runoff, rainfall, and snowmelt from nearly 9,000 kilometers of land and the water is collected in two primary reservoirs managed by the City of Calgary. To ensure a safe, consistent, supply of water for its customers, the City of Calgary must keep a close eye on both the quality and quantity of water in these rivers and reservoirs. One of the biggest challenges in doing so is the region’s annual floods. Each year, between May and June, snowmelt, runoff, and rainstorms cause the water levels in the rivers to increase substantially. Preparing for flood-level waters is part of the utility’s annual plans, but predicting when, precisely, they would occur was another matter. Water tables can change quickly and the utility must balance flood risks against continuing to meet user demand and maintaining reservoir levels and water quality. During a flood event, the utility is faced with a surge in water volume through its system. Before water reaches the reservoirs, it must be treated and the sudden increase in volume caused by the floods often overwhelmed the treatment plants, resulting in quality issues. Furthermore, City of Calgary lacked timely information that would let it reduce reservoir volume in advance of a flood. As a result, emergency response often struggled to respond as flood waters reached downtown. The resulting damages — including residential and commercial insurance claims, water quality issues, system downtime, and regulatory fines — could total in the millions. To reduce the impact of floods on its customers and its business, City of Calgary, turned to the PI System.

Sensors aren’t always placed in locations that make data networking connectivity easy. One rather extreme example would be the slopes of Iceland’s Eyjafjallajökull volcano, which is capable of making ground travel in the area extremely hazardous. In extreme events, like the eruptions of 2010, Eyjafjallajökull can emit so much ash that it disrupts air travel all over Europe.The Icelandic Meteorological Office observes Eyjafjallajökull with a wide array of sensors ranging from seismographs and GPS units to flow meters and thermometers. They can’t control the volcano, but they can make informed predictions about its behavior.Between lava flows, ash fall and earth tremors, installing and maintaining a data communications cable run on a live a volcano would be a very expensive proposition. The Icelandic Meteorological Office needed a wireless solution that could do its job in a very tough environment.

The City had been staffing their WWTP system 24/7, but could see that with the SCADA upgrades that the night operator was unproductive and bored. The overnight position was difficult to keep staffed and if a dramatic event occurred at either facility, the night shift operator would likely be unable to handle it himself.

Wetland Sewer Overflow Reduction
The City of St. Joseph needed high-value solutions to reduce combined sewer overflows as a component of a large program to address regulatory requirements. During the design and construction of a wetland park, intelligent stormwater infrastructure was chosen to attenuate peak flows and help reduce wet-weather flow to the combined sewer.

For scientists at the City of Lakeland, Florida, manually monitoring lake levels to prevent flooding is a time-consuming, resource-draining task, especially during the nearly four-month rainy season.“Maintaining balanced water levels is critical to avoid flooding in residential areas and conserve enough water for the dry season,” said Laurie Smith, manager of the City of Lakeland’s Lakes and Stormwater Division. “Our technician has to drive back and forth between 11 lakes and make sure the levels don’t get too high.”
