Differential Pressure Measurement Scheme
Hello dear members,
I would like to talk about an issue about the instrumentation of filtration equipment, installed in parallel, such as sand filters. Generally, it is seen in different plants that a dedicated set of the differential pressure measuring device for each under pressure filtration equipment. For example, if 8 pressure sand filters are installed in parallel, 8 DPTs are placed in total. On the other hand, some designers say one differential pressure transmitter is adequate for the whole filtration colony. What do you think about the appropriate scheme regarding this issue?
