Refueling stations from Processkontroll previously incorporated flowmeters based on a 4-20 mA analog mass flow signal, but the company desired a new solution that would require less mounting space and deliver a much higher level of performance. Specifically, they were looking for direct integration into an automation system, enhanced ease of use and improved customer service.
After considering several options, Processkontroll ultimately chose Coriolis mass flow technology from Siemens: the Sitrans FCS200 sensor combined with the Siflow FC070 Ex CT transmitter. One of the most important factors driving Processkontroll’s decision was the fact that the Siflow FC070 can be integrated seamlessly into the Simatic S7300 PLC system with a single cable. The straightforward installation process and very small number of required components saves Processkontroll time and money. The Siemens solution is also flexible enough for integration into a distributed ET200 IO Profinet/Profibus station, which means that Processkontroll can successfully meet a wider range of customer requirements.
Equally crucial in the selection process was the user-friendliness demonstrated by the Siemens system. The new solution makes commissioning and monitoring very easy, with all application parameters, process values (including mass flow, volume flow, temperature and density) and even auto zero adjustment available from the Simatic touch screen. Integration with Simatic also offers the company the ability to respond more rapidly to customer service needs. From the Processkontroll office it is possible to connect to the customer’s control cabinet and gain instant access to all necessary flowmeter data, minimizing response times and greatly reducing travel costs. The Simatic remote access function even allows service engineers to connect to the system from a Smartphone, regardless of their current location.
