SITRANS FC410 Coriolis Flowmeter

There has been a growing need in the marine industry for accurate flow measurement of fuel aboard ships. This requirement has come about due to the increased focus on fuel utilization and fuel security. The primary concern has been the security of the fuel stored on the ships, which at times can be misdirected for elicit purposes. Additional uses are in maintaining drive and generator engine performance records of fuel utilization, when the ships are at sea or at dock.

One customer stated that they have millions of U.S. dollars’ worth of fuel aboard the ships at sea at any given time, and all of that fuel is completely unaccounted for. They needed a way to accurately measure the fuel’s utilization and measure the fuel’s quality while at the same time preventing tampering with the fuel systems. They also required a solution that was compact to fit into areas where space was limited.

After discussions with the customer it was determined that the Siemens FC410 Coriolis flowmeter would be the optimal solution to meet their needs. The FC410 comes with Modbus I/O, which affords the customer easy integration into their PLCs. Modbus also provides a very quick responding system that allows easy access to a host of critical process data points that can be stored for history or evaluated in real time. Siemens Coriolis solution is the world’s smallest Coriolis sensor in the utilized tube size. The small size easily addressed the difficult installation requirements.

The customer not only required flowrate accuracy, they also required density and temperature accuracy in order to properly ascertain the quality and makeup of the fuel. The Coriolis flowmeters also needed to have very low pressure loss within the fuel delivery system in order to avoid fuel starvation, which could result in catastrophic engine failure. The Siemens FC410 has one of the lowest pressure losses for a flowmeter of its size.

The FC410 also had to meet stringent delivery requirements to meet the critical build schedule. Delivery had to be made within two weeks of the order being entered. With Siemens customer-tailored local inventory, the customer was able to easily meet their delivery requirements.

Finally, since the ships are utilized worldwide, the customer required that field service be available on the Coriolis flow sensors anywhere when the ships were in port. With Siemens worldwide presence and technical support team, service was available for all the ships when in port.

The SITRANS FC410 provides superior digital interface and communication technology. Reduced interference is assured because each process signal is immediately digitized. Internal high-speed signal processing provides fast and reliable process parameters, which are provided on the output side with a refresh rate of 100 Hz.

One of the most compact flowmeters on the market, the SITRANS FC410 enables space and money-saving installation in any position. The world’s shortest installation length allows multiple devices to be installed in the tightest of spaces. The simple wiring enables safe and time-efficient installation.

With a mass flow rate accuracy of 0.1 percent and a maximum reproducibility error of 0.05 percent, the SITRANS FC410 meets the most stringent accuracy requirements. Additionally, the highly accurate real-time density measurement accuracy of 1 kg/m3 greatly benefited the customer in maintaining the fuel composition. This performance makes the SITRANS FC410 perfect for use in these ship board applications.

The SITRANS FC410 is certified by ABS (American Bureau of Shipping). This is a guarantee of unsurpassed safety and reliability in Marine applications. The SITRANS FC410 is also FM certified and can be used in hazardous areas up to Class 1 Division 1.
