LDY-25S electromagnetic flowmeter is mainly used to measure the volume flow of conductive liquids and slurries in closed pipelines, including highly corrosive liquids such as acids, alkalis, and salts. The measurement principle is Faraday's law of electromagnetic induction. It is an instrument that measures the flow of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. LDY-25S electromagnetic flowmeter signal processing steps: 1. First confirm whether the pipeline is filled with fluid. 2. If the pipe is too close to the wall, the probe can be installed on an inclined pipe diameter instead of a horizontal pipe diameter. The Z method should be used to install the probe
3. Carefully select the dense part of the pipe And fully polish it and apply sufficient coupling agent to install the probe; 4. Carefully and slowly move each probe near the installation point to find the maximum signal point to prevent ultrasonic waves caused by scaling on the inner wall of the pipe or local deformation of the pipe. The beam reflects out of the expected area and misses the installation point that can receive a stronger signal; 5. For metal pipes with serious inner wall scaling, you can use the method of hitting to cause the scaled parts to fall off or crack, but it should be noted that this method sometimes causes Because there are gaps between the scale and the inner wall, it does not help the transmission of ultrasonic waves at all.
