Mass of flow measurement Different fluids have different densities and their volumes change with temperature. There are even effective flow meter that helps you to measure the fluids, Resource management In periods of scarcity of resources, flow rate monitors provide a simplistic way to ration resources.

Taking regular, reliable and accurate flow rate measurements is one of the best ways to protect the safety of personnel. A safer working environment is likely to be a more productive environment, with machinery operating efficiently and downtime kept to a minimum.

There are inherent cost-efficiencies that arise as a direct consequence of adhering to high standards of quality control and plant safety. Furthermore, if pipelines and machinery are kept operating optimally, the subsequent reduction in maintenance delivers tangible savings.

Flowmeters measure linear, nonlinear, volumetric or mass flow rate of a liquid or a gas. Login Saved. Topics to browse. Who to work with. Manufacturers Consultants Contractors. An important and perhaps overlooked question, is what the instrument is supposed to do versus what is it able to do? Direct mass flow measurement is an important development across industry as it eliminates inaccuracies caused by the physical properties of the fluid, not least being the difference between mass flow and volumetric flow.

Mass is not affected by changing temperature and pressure. This alone makes it an important method of fluid flow measurement. Volumetric flow remains valid, in terms of accuracy , provided that the process conditions and calibration reference conditions are adhered to. Volumetric measuring devices, such as variable area meters and turbine flow meters, are unable to distinguish temperature or pressure changes.

One method of mass flow measurement employs the phenomenon of Coriolis force. The operating principle is basic but very effective. A tube is energised by a fixed vibration. This change in frequency is in direct proportion to the density of the fluid — and a further signal output can be derived.

Having measured both the mass flow rate and the density it is, interestingly, therefore possible to derive the volume flow rate. The Coriolis principle, applied as a mass flow meter, therefore has its place within fluid measurement and control within the traditional Process Industry. Perhaps more importantly though, the additional features of the technology allow for an extension of the accuracy and precision into other, more non-traditional, applications.

Take, for example, filling and dosing applications across a great many industries and the replacement of both weighing scales and the gravimetric method. The weighing scale is located under a valve outlet nozzle and, after a zeroing procedure once the vessel being filled is in position, the valve will open.

The weighing scale will send a signal to the PLC or control unit and, once the batch has been reached, the valve will close. Multiple dosing, building up a recipe, is achieved by moving the vessel to the next dosing point in line and repeating the process.

Another example of process improvement has been seen within the field of specialist chemicals. The customer was unaware that low to ultra-low flow control was possible with a Coriolis instrument resulting in the raw ingredient being mixed with water to create a carrier volume.

This higher volume was then metered and dosed into the main product flow. The process added cost to the production method and, as the dilution step added variability to the concentration of the additive, product quality was often compromised with a resulting additional cost of re-work. Furthermore, the final process step saw the bulk material being heated and stirred to evaporate the added water to reduce volume and increase concentration. The energy requirement to do so was significant and the operational stock-holding was high.

By understanding the extended capabilities of Coriolis instruments it was possible to establish that the concentrated raw ingredient could be added via a highly accurate low flow Coriolis Flow Meter directly coupled and controlling a precision pump.

This solution ensured that the costly addition and removal of the water could be eliminated and that very close tolerances on the dosage rate, and hence final product quality, could be maintained. The inclusion of multiple synchronous injection points eliminated the costly clean-down process and the reduction of working process volume also reduced the stock holding inventory further reducing operational costs.

Re-producible product quality has been increased, productivity has been increased, wastage has been reduced, energy consumption has been reduced and operational costs have also been dramatically reduced. Standard on-board firmware can be utilised to immediately match the required dosage rate to any variability within the main flow line. This facility eliminates any time lag in process response and further enhances the very tight tolerances on product quality.

A host of secondary benefits have also been utilised within the solution. The density of the concentrated natural raw ingredient is measured, recorded and trended thereby allowing tracking of the natural innate variability and further fine-tuning of the control process.

The pump steering signal is utilised for condition monitoring and as a preventative maintenance tool.
