Clean water utility billing by electromagnetic flowmeter Communication Bacnet DN80
Work theory:
The magnetic flowmeters use Faraday’s Law of Electromagnetic Induction to determine the flow of liquid in a pipe. In a magnetic flowmeter, a magnetic field is generated and channeled into the liquid flowing through the pipe. Following Faraday’s Law, flow of a conductive liquid through the magnetic field will cause a voltage signal to be sensed by electrodes located on the flow tube walls. When the fluid moves faster, more voltage is generated. Faraday’s Law states that the voltage generated is proportional to the movement of the flowing liquid. The electronic transmitter processes the voltage signal to determine liquid flow. By comparison to many other flowmeter technologies, magnetic flowmeter technology produces signals that are linear with flow. As such, the turndown associated with magnetic flowmeters can approach 20:1 or better without sacrificing accuracy. They represent about 23% of all flowmeters sold.
Applications:
Electromagnetic Flow Meter reduces lifecycle costs and unplanned shutdowns by accurately measuring water and wastewater flows in a variety of utility applications. It help users take advantage of improved installation, maintenance and process-management practices. With fully welded sensor construction and an isolated, replaceable termina, it is the most dependable meter available for utility and water applications.
