The Micro Motion R-Series flowmeter for hygienic applications is believed to be the only low-cost Coriolis meter that is both 3 A authorised and EHEDG (European Hygienic Equipment Design Group) certified.
Advantages of using the R-Series include:
* Batch in-line and directly measure mass and volume flow without additional equipment. Drastically reduce costs, eliminating expensive batching storage tanks.
* Measure liquids, gases, and slurries without compensating for pressure or temperature variations. Improve repeatability and double rangeability under changing process conditions. Multiple liquids of various densities can flow through the same flowmeter without the need for adjustments or recalibration.
* Easy to clean in place with self-draining stainless steel design, and standard 32 Ra (0,8 µm) internal surface finish.
* Simple to install with a choice of integral transmitter or easy four-wire remote-mount transmitter.
* Improve accuracy, and eliminate fluid conductivity limits and density assumptions often made with more traditional volumetric flowmeters such as differential pressure/orifice, magnetic, positive displacement, turbine, and vortex.
* Reduced ongoing maintenance and concerns over leaking, wear, or calibration drift because Micro Motion meters need: no flow conditioning, no straight pipe runs, no liners, and no electrodes.
* Save money over the life of the meter with reduced process variability and maintenance.
* No moving parts, no special mounting or flow conditioning required.
Micro Motion Coriolis meters are being used worldwide successfully in various applications:
Batch control
A manufacturer of baked goods was having trouble keeping liquid sponge within weight control limits. When it replaced its positive displacement meters with Micro Motion Coriolis meters, raw material costs declined, product quality and consistency improved, and it reduced space requirements by eliminating a lot of the bulky equipment.
Custody transfer
Loading food and beverage products into tanker trucks for shipment requires a high degree of accuracy. In a custody transfer case involving juice concentrate, the value of each tanker load was based on the percent sugar solids content. Time-consuming and labour-intensive manual sampling and lab analyses were being used to test each load. When the concentrate fell outside specified limits, the load had to be rebatched.
After installing Micro Motion meters, mass flow, density and total concentrate delivered to the tanker could be measured accurately, continuously and automatically as the tanker was being filled. Because these critical parameters could be controlled while loading, the need to unload and rework off-spec product was eliminated. More tankers could be loaded each day with no variance in weight-saving time and money.
Continuous blending
A soft drink producer which switched from batch to a continuous blending system utilising Micro Motion meters in the blend unit realised instant benefits. The production line was reduced to a single compact unit, saving space and enabling increased capacity without plant expansion. And by accurately monitoring the blend of a variety of raw ingredients in-line, product consistency and quality showed dramatic improvement.
