Static electricity is a charge that is at rest, or does not flow (flowing charges form an electric current). Static electricity is formed when charges gather on an object or surface, and charge is divided into positive and negative charges, that is to say, static electricity is also divided into two kinds of static electricity, namely positive static electricity and negative static electricity.
In the past, mechanical heat meters were the main heating metering products used by thermal companies. Mechanical heat meter has impeller rotating, impeller rotation has the role of mixing, so it is very conducive to positive and negative charges offset each other, and ultrasonic heat meter does not have the function. Therefore, ultrasonic heat meter than mechanical heat meter more easily with static electricity, and is stronger static electricity. The hot water generated by static electricity flows in the pipeline. The water flow is a relative displacement in a single direction with the pipeline, which constitutes a very easy condition to generate static electricity. In particular, most of the composite pipes made of metal and plastic materials are now used, which are easier to generate strong static electricity.
