High-precision mass flow meter cleaning method
The high-precision mass flowmeter is a new type of flow measurement instrument that directly measures the mass flow of fluid in a closed pipeline according to the principle of Corio. The high-precision mass flowmeter generally consists of a signal measurement sensor and a signal converter.
Because the high-precision mass flowmeter has the ability to directly measure the mass flow of the fluid, the measurement accuracy is high, the application range is wide, the installation requirements are low, the instrument is reliable in operation, and the maintenance rate is low. The high-precision mass flowmeter has been widely used in petroleum and chemical engineering. Flow measurement in fields such as metallurgy, thermal power, electricity, and food.
High-precision mass flow meters use the world's new technology. The use of constant-current low-frequency rectangular wave or dual-frequency rectangular wave excitation not only has the advantages of rectangular-wave magnetic field, but also overcomes the shortcomings of the sine-wave magnetic field; it can also eliminate power supply voltage fluctuations, power supply frequency changes and excitation coil impedance changes caused by Errors; excellent zero stability and immunity to fluid noise interference. Therefore, it has the characteristics of high stability and high reliability. The measuring principle is based on Faraday's law of electromagnetic induction. The high-precision mass flow meter consists of a sensor and a transducer. The sensor is mounted on the measuring pipe. The transducer can be combined with the sensor and called the integral electromagnetic flowmeter. The converter is installed on the Within 30 meters of the sensor or within 100 meters of the sensor, the connection between the two is shielded by a cable called a separate magnetic flowmeter. The main components of the high-precision mass flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. High-precision mass flow meters are mainly used to measure the volumetric flow in conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, all kinds of acid, alkali, salt solution, food slurry, etc., are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as environmental protection, municipal management, water conservancy construction and other fields.
