1. Sensor Identification 1. The sensor has five leads, which are: Red with shielding (Signal Line A), Black with shielding (Signal Line B), Yellow and Green striped (Ground Line C), White (Excitation Line X), Black (Excitation Line Y). 2. Measure the resistance values using a multimeter in ohm mode: In the empty pipe state, the … Read more
In the chemical, petroleum, and energy industries, flow meters serve as critical process monitoring devices, responsible for material measurement, pipeline pressure monitoring, and other core functions. However, traditional Profibus buses frequently encounter signal loss and data errors in long-distance, high electromagnetic interference environments, leading to abnormal flow meter data, delayed control commands, and even production … Read more
Flow sensors are precision instruments used to measure the flow rate of fluids (liquids or gases) by converting fluid flow parameters into measurable electrical signals for flow monitoring. Modern flow sensors integrate multidisciplinary technologies such as fluid mechanics, electronics, and materials science to meet various measurement needs, from laboratory micro-flows to industrial large flows. 1. … Read more
