No compensations equal fewer sources for miscalculations
The fact that the Yokogawa ROTAMASS Mass Flow Meter, in addition to the directly measured mass flow, can provide directly measured density and calculated volumetric flow, means that all measurement translates to a signal without the need of a flow computer or another source for compensation or conversion. This provides a setup with fewer sources for error and mistakes, and by adding signals for sensor errors and self-diagnostics as well, it ensures that the signals you get are less likely to get tampered with and are ready more or less as they are for further use in other systems.
Well-suited for demanding environments
In general terms, Coriolis Mass Flow Meters are relatively sensitive instruments. They need to be installed in well-aligned piping, so they are not affected by stress, minor movements and vibration in the system. The Yokogawa ROTAMASS-series is designed with a unique and patented ‘box-in-box’ feature, that makes it far less sensitive to stress, movement and vibrations. For installations in demanding and harsh conditions like on a ship, the ROTAMASS-series proves itself ideal with its more robust layout.
Minimize maintenance on board
The Coriolis Mass Flow Meter is in general an instrument that requires very little attention once it is installed correctly. As it has no moving parts and no sub-millimeter tolerances, the risk of breakdown or clogging is minimal. Within the flow meter itself, there is literally no parts that needs replacement over the lifetime of the instrument. And since the sensor is insensitive to particles and debris in the stream going through it, there is no requirement towards filtering the fuel before the flow is measured.
Cost effective setup
Eliminating the need for regular maintenance of the flow meter reduces the attention required in itself. But when you avoid installing a filter before the instrument, it further adds to the time saved as monitoring of the pressure drop over the filter and the periodical filter cartridge changes are also obsoleted. All the time and required attention that a typical volumetric flow meter with a pre-filter installation requires, can be spend on more productive and performance enhancing initiatives, thereby allowing the crew to make the vessel more cost efficient.
The cost of saving money on instruments
In general terms, you most often get what you pay for when it comes to instrumentation. But there is also the factor of sourcing the correct instrument with a suitable setup. So, the total cost of an instrument can be divided into two categories; the actual cost of the instrument in monetary terms, and the cost of time spend on making sure the suitable instrument is selected and installed correctly. And cutting cost too much on either of the two categories can result in an excessively high final cost.
