Electromagnetic flow meters are instruments that measure the volumetric flow rate of conductive liquids based on the principle of Faraday's law of electromagnetic induction. They are a product of the combination of fluid mechanics and electromagnetism. The GCF-D series electromagnetic flow meters have the advantages of rectangular wave magnetic fields while overcoming the disadvantages of sinusoidal wave magnetic fields; they can also eliminate errors caused by fluctuations in power voltage, changes in power frequency, and changes in the impedance of the excitation coil; and they have good zero-point stability and are not affected by fluid noise interference.

Features

• Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity
• There are no flow-restricting components inside the measuring tube, no pressure loss, low straight pipe section requirements, and unique adaptability to slurry measurement
• Wide coverage range of nominal diameters DN6-DN3000, with a variety of liner and electrode options, applicable to various measuring media, with good corrosion resistance and wear resistance
• The converter uses programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and reduces power consumption
• The converter uses a 32-bit embedded microprocessor, with full digital processing, fast computing speed, strong anti-interference ability, reliable measurement, high accuracy, and a flow measurement range of up to 1500:1. The range can be modified online according to the user's actual needs
• High-definition backlit LCD display, optional Chinese and English menu operation, convenient and easy to use
• With digital communication signal outputs such as RS485, RS232, Hart, and Profibus (optional)
• With conductivity measurement function, it can determine whether the sensor is empty, and has self-checking and self-diagnosis functions
• Uses SMD components and surface mount (SMT) technology, high circuit reliability
• Infrared hand-held device operation, 115KHZ communication rate, long-distance non-contact operation of all converter functions (optional)
• There are three internal meters that can separately display the forward cumulative amount, the reverse cumulative amount, and the difference cumulative amount. There is an internal power-off clock that can record the power-off time (optional)
• Can be used in corresponding explosion-proof environments

Application Areas

The GCF-D series electromagnetic flow meter can be used to measure the volumetric flow rate of conductive fluids in closed pipes, and can also be used to measure the volumetric flow rate of corrosive liquids such as strong acids and strong alkalis, and uniform liquid-solid mixtures such as mud, ore pulp, and pulp. As a high-precision flow measurement instrument, it is widely used in the flow measurement and control of industrial and agricultural production processes in petroleum, chemical, iron and steel metallurgy, water supply and drainage, heating, water conservancy irrigation, water treatment, environmental protection wastewater monitoring and control, papermaking, light textile, medicine, food, biology, and fine chemical industries.
