AI Technical Summary
Existing pipeline speed measuring devices have short lifespans and poor accuracy. In particular, when the pig runs at too high a speed, the mileage wheel is prone to slippage, resulting in large speed measurement errors and affecting the operation of the speed-adjustable pig.
A non-contact speed measuring device is used, which utilizes magnets and force sensors to detect the electromagnetic resistance generated by the magnets inside the metal pipe. Combined with an accelerometer and controller, the speed is calculated through the principle of electromagnetic induction to achieve accurate speed measurement.
It improves the lifespan and accuracy of the speed measuring device, has a simple structure, low cost, and is easy to operate. It is suitable for different pipeline conditions and can accurately measure the speed of the instrument in the pipeline in real time.
