1. Detailed information of split type electromagnetic flowmeter
The measurement principle of split type electromagnetic flowmeter is based on Faradays law of electromagnetic induction. The split type electromagnetic flowmeter consists of a sensor and a dust converter. The sensor is installed on the measuring pipeline, and the converter is installed within 30 meters or 100 meters from the sensor, connected by a shielded cable. The main components of the split type electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. Mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc., are widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, municipal management, water conservancy construction, etc. to measure high temperature, high humidity, and difficult to observe environments. 2.

2. Introduction to split type electromagnetic flowmeter
Electromagnetic flowmeter is classified according to the assembly method of converter and sensor, and there are split type and integrated type.. Split type electromagnetic flowmeter is the most commonly used form of electromagnetic flowmeter, as shown in the figure below. The sensor is connected to the pipeline, and the converter is installed near the sensor in the instrument room or easily accessible to people, with a distance of several tens to hundreds of meters. To prevent external noise from entering, signal cables usually use dual core shielded wires. When measuring liquids with low conductivity and aiming to gather more than 30m apart, in order to prevent signal attenuation caused by the capacitance of the cable, it is also required to connect a shielding driver with the same potential and low impedance source as the core wire to the inner shielding. The converter of the split type electric side chain magnetic flowmeter can be kept away from harsh on-site environments, making electronic component inspection, adjustment, a
