In allusion to the method of using the frequency converter&PID regulation to control the steam boiler pump in the article, it has proposed to use the output contact bounds of digital indicator to control the frequency converter. We have chose boiler water level measuring meter&frequency converter and made the electric draw?ing of the main circuit, set up the parameters of the frequency converter. Actual motion indicated, equipment op?eration more reliable, easy to adjust it can be generalized in the future.
