Working principle and technical parameters of plug-in electromagnetic flowmeter


The plug-in electromagnetic flowmeter has the same measuring principle as the pipeline electromagnetic flowmeter. According to Faraday's electromagnetic induction law, the plug-in electromagnetic flowmeter sensor is mainly composed of a measuring head, an insertion rod, an insertion mechanism and a converter, and can be mounted on a steel pipe. Installed on the cast iron pipe on the cement pipe, the depth of insertion is usually selected at the highest point of the pipe center flow velocity, or the average flow velocity point. The function is to linearly convert the liquid volume flow value flowing into the pipe into an induced potential signal and send this signal to the converter through the transmission line. The converter should be installed not far from the sensor, amplify the signal from the sensor and convert it into a standard electrical signal output proportional to the flow signal for display, accumulation and adjustment control.
The SC-LDEC series of plug-in electromagnetic flowmeters are used to measure the volumetric flow in conductive liquids and slurries in closed conduits. It includes highly corrosive liquids such as acids, bases and salts, and is especially suitable for large-diameter pipe measurements. Plug-in electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields.
