Cover Story frequencies means that both relationships – resonance frequency and error – are known. The instrument uses this information to determine the value at which this error ratio, which is tied to the entrained gas, is almost zero. It then adjusts the oscillation frequency accordingly. Elimination of the measurement error caused by heavy gas entrainment has a considerable impact on the incoming supply of the raw milk. Compared to the processes available to date, the Promass Q allows food manufacturers to measure the quantity of incoming raw milk more accurately than with currently-available Coriolis mass flowmeters and as a result, significantly optimize the internal raw materials settlement even further. Accounts settlement with the dairy farmers is more accurate as well. Determining overrun levels The Promass Q multifrequency technology not only makes it possible to eliminate mass flow measurement discrepancies with fluids. It can also precisely measure the overrun in other products where various gases are infused, such as cream cheese or ice cream. In this case manufacturers strive to create an especially light and fluffy consistency, such as in cream cheese. In environments where experience served as the basis for entrained gas values and the amount of gas was adjusted after drawing samples – after all, raw milk is subject to certain fluctuations – overrun can now be measured with a high degree of accuracy. This in turn helps reduce fluctuations in the quality of the end product. The Promass Q has repeatedly demonstrated its suitability for measuring overrun. Users were able to monitor and regulate the entrained gas levels in the process by means of density measurements, thus preventing off-spec batches or fluctuations in product quality. Digital communications interfaces and internal self-test function Beyond the sensor with its multifrequency technology, the electronics is what makes it easy to integrate the Promass Q into existing systems. In combination with the new Proline 300/500 transmitter variant, the sensor is capable of forwarding the signals via a wide range of digital communications technologies such as Profinet, which also helps support the digitalization strategies for the production processes. In addition, the Heartbeat internal testing function offers a key way to simplify quality management. Companies that operate according to ISO 9001, IFS or other certification standards are frequently required to calibrate and/or verify critical measurement points. And this is precisely where the internal, TÜVcertified verification function comes into play. This feature determines the status of the instrument, with a likelihood of 94 percent, and delivers a clear indication of whether the device is still measuring within specifications or is experiencing problems. Users thus enjoy an even better way to document the traceability of individual batches while reducing the amount of red tape at the same time. Promass Q - jack-of-all-trades The Meierei Barmstedt example illustrates that by deploying the Promass Q, demanding food manufacturing processes can be even more reliable and cost-efficient. Manufacturers are also in a better position to address challenges such as accurate accounts settlement or full cost pricing. The Promass Q is a multivariable measurement instrument that supplies users not only common values such as mass flow, density or temperature, but also quality-relevant parameters such as overrun or brix value. The Promass Q is a genuine jack-of-all-trades designed to help food manufacturers with their daily challenges. fmt The Authors: Manuel Martini is Product Manager Ultrasonic/Teqwave at Endress+Hauser Flow Florian Kraftschik is Marcom Manager Media Relations at Endress+Hauser Messtechnik GmbH+Co.
