摘 要：
A new type of automatic display of rotational speed for submer- sible pump has been developed to overcome the drawback to the traditional methods of speed measuring for submersible pump.The principle has been presented and the error analysis in measuring data has been given.All these show that the instrument developed can display the rotational speed of submersible pump automatically and real-timely,and can also meet the requirement of measuring precision.
