The electromagnetic flowmeter is not affected by external factors such as temperature, pressure, viscosity, density, etc. The pressure inside the measuring tube is not contracted or the pressure loss of the protruding part. In addition, the initial signal detected by the flow element is accurate with the average flow velocity of the fluid. The linearly varying voltage, which has nothing to do with other properties of the fluid, has great advantages.
According to the characteristics of large flow, large impurity, low corrosivity and certain conductivity, the electromagnetic flowmeter is a good choice for measuring the flow rate of sewage. The utility model has the advantages of compact structure, small volume, convenient installation, operation and maintenance. For example, the measuring system adopts intelligent design, the overall sealing is strengthened, and the utility model can work normally in a harsh environment. The neodymium rubber lining and the electromagnetic flowmeter with molybdenum stainless steel (OCrI8Ni12Mo2Ti) electrode can be used to meet the requirements of sewage flow measurement.
