This article is reproduced from: http://www.china-yokogawa.com/News/220.html. Keywords of this article: Yokogawa mass flow meter. The Yokogawa mass flow meter has a special feature, which is the DSP digital signal processor function. This technology enables better filtering, reduces the flow meter’s sensitivity to noise, improves measurement accuracy, and has received many positive reviews. Next, the editor will introduce to you the functions of the digital signal processor in mass flow meters. The DSP digital signal processor in the Yokogawa mass flow meter is a microprocessor for real-time signal processing. In the flow meter, the measurement tube is made to vibrate at a known frequency; therefore, any frequency outside this vibration range is considered “noise,” and it must be removed in order to accurately determine the mass flow rate. The DSP digital signal processor in the Yokogawa mass flow meter can be used for gas measurement, but it generates significant noise during the measurement process. To enable better filtering using current DSP technology and further reduce the sensitivity of mass flow meters to noise, high-precision sensors from the HighAccurate series can be used, thereby reducing the noise that is mixed in with the flow signal. Compared to using time constants to suppress and stabilize signals, this signal processor, with its multi-parameter digital transmitters, offers a response time that is 2 to 4 times faster than that of traditional transmitters that use analog signal processing; such a faster response time improves the efficiency of short-batch control. This is one of the main advantages of using digital signal processing technology ； Another advantage is the ability to filter real-time signals at an increased sampling rate, which reduces the response time of the flow meter to step changes in flow rate. The digital signal processor used in Yokogawa’s mass flow meters plays a very important role in these applications; it not only improves the accuracy of measurements but also enhances their repeatability.
