1、 Overview
Inorganic acid alkali wastewater pipeline flowmeterIt is a widely used form of electromagnetic flowmeter. Sensors are connected to pipelines, and converters are installed in instrument rooms or near sensors that are easily accessible to people, with distances ranging from 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 a distance of more than 30m, in order to prevent signal attenuation caused by partial capacitance of the cable, it is also required to connect the inner shielding to a shielding driver with the same potential and low impedance source as the core wire. The converter of Kaifeng and Lishi Instrument's split type electromagnetic flowmeter can be kept away from harsh on-site environments, making electronic component inspection and parameter setting more convenient. Widely used in flow measurement and control of production processes in industries and agriculture such as petrochemicals, steel metallurgy, water supply and drainage, irrigation, water treatment, environmental wastewater control, papermaking, pharmaceuticals, and food.
