What is the function of the flow display instrument?

The flow signal obtained from the flow measurement (sensing) section and its total amount of accumulation are displayed on the display mechanism. These display mechanisms are either integrated with the measurement section or with the measurement section (ie flow sensor or transmitter, Also known as a meter) phase separation, composed of independent units, called display instruments (commonly referred to as secondary instruments). In the past 10 years, the flow display instrument has gradually added various calculation functions, such as square root operation, integral calculation, engineering operation and so on.
Since the microprocessor entered the instrument, the flow signal processing technology has undergone a revolutionary change, and the structural composition has been completed from a programmable flow calculation display device that requires more than a dozen unit combination meters. The display is more simplified to several digital tubes. People call this kind of instrument a fiow computer or a flow calculator. In fact, it is a special computer with the main task of completing flow information processing. The flow display instrument described in this book mainly refers to this. A flow signal processing and display device with a microprocessor or a single chip microcomputer. Due to the different roles played in flow measurement, the flow display instrument has different functions. According to the difference of use, it has different names, such as intelligent flow totalizer, flow calculator, intelligent heat meter, flow batch control. And so on.
Domestic instrument manufacturers also have a variety of flow display instrument product supply markets, such as SXS-3111 flow totalizer from Shanghai Regulator Factory, SDC-AI flow totalizer from Shanghai Mingli University Instrument and Meter Factory, and LRB type heat flow totalizer. instrument. These products are similar, but each has its own market share. However, due to lack of detailed information, it will not be described in detail here.
