Maintenance-free, regardless of heavy deposits
In pump shafts, the deployed measurement technology has to contend with material that can quickly influence the measuring results. In Zeulenroda, measuring with a suspended pressure transmitter through a pipe that reached down to about 10 cm above the ground was difficult. Due to a pile of sand that formed at the bottom of the shaft, inaccuracies kept occurring. To solve the problem, employees of the sewage treatment plant decided to try radar measurement with a VEGAPULS C 23 with encapsulation. The measurement now takes place contactlessly at the upper rim of the shaft. From there, the radar sensors operate without effect from dirt and buildup – or from “annoying” sand accumulations. In Zeulenroda, VEGAPULS C 23 proves that it’s possible to have a clear view despite all adversities: In any case, the sensor doesn’t care at all about accumulations of material, no matter what kind.
Water Flow Measurement
Tennacola S.p.A is responsible for the integrated water cycle of 26 municipalities, 12 of which are in the province of Macerata and 14 in the province of Fermo.
The water handling systems manage the whole water cycle, that is the set of operations involved in extracting drinking water from springs, transporting it to reservoirs and individual users, collecting wastewater and cleaning it, and finally, releasing it back into surface water bodies.
This wide range of services is unique and guarantees functionality and efficiency in protecting water resources and the environment as a whole.
VEGA radar sensors of type VEGAPULS C 21 are used to measure the flow of water taken from the Tennacola tributary. The water, extracted directly from the source, is very good water in terms of its organic, chemical and physical properties: In fact, the water from the Tennacola has a quality comparable to some of the best mineral waters on the market. Tennacola water is so clean and pure because it comes from natural springs located in pristine environments upstream, where there are no developments or other human activities. The spring water flows into a settling basin, then into a water reserve tank. It eventually enters the supply tank via a trapezoidal weir, where flow is measured by level change in proportion to the flow rate.
Highly accurate monitoring of the changes in level allows the flow rate of the extracted water to be measured correctly at all times. Calculation of the instantaneous flow rate and total flow volume is done by using a level to flow rate curve, which is programmed into a VEGAMET 861 controller.
Installing and commissioning the sensor is easy, because it measures without physical contact with the medium. It comes already equipped with a cable and IP68 protection. Calibrating the sensor and uploading the weir linearisation curve is also straightforward, as this is carried out via a smartphone and the VEGA Tools app, which even provides a calculator for pre-defined flow-curves for standard flumes and weirs from dimensional input.
SITOP SIMATIC Design – The optimal supply for SIMATIC S7 and more
Regarding design and functionality, the original power supplies of the SIMATIC integrate optimally into the PLC network. The startup and power reserves of the SITOP power supply units meet the requirements of the respective controllers. In addition, the mounting options of both components are the same. All of this ensures that controller and power supply or peripherals are perfectly matched. In addition to the SIMATIC systems, the SITOP power supply units in SIMATIC design also supply further consumers reliably with 24 Volts.
Location Intelligence: Optimization of production and logistics processes
How can you ensure efficient workflows in production and logistics? Location Intelligence, a software application for locating systems, increases transparency over logistics and production by combining the position of objects with order information. Using real-time tracking and analytics, bottlenecks and other anomalies can then easily be detected and eliminated.
