∷产品简介∷
FFM62 intelligentized electromagnetic flowmeter is a stable and precise flowmeter which is developed on the basis of Faraday law of electromagnetic induction and weighted function magnetic field distribution technology. The low-frequency rectangular wave excitation and intelligentized transformation technology are adopted to ensure the stable zero and precision of 0.5 grade and repeatability of 0.25%. The flowmeter is applicable to the flow measurement of the conducting liquid and fluid (such as pure water, sewage, all kinds of acidic, basic and salt solutions, slurry, pulp, paper pulp and liquid for food)inside the closed pipes. It is widely applied to the industries including metallurgy, paper making, water treatment, chemical processing, light industry, textile, power and mining.
technical advantages of FFM62 intelligentized electromagnetic flowmeter：
Intelligentized transducer adopts the internationally advanced MCU and SMT technology. It is reliable in performance, high in precision, low in power consumption, stable in zero, and convenient for parameter setting. The Chinese LCD in the form of lattice is provided.
The high-precision constant current source low-frequency rectangular wave excitation is adopted to ensure the stable magnetic field. It is free from the electromagnetic interference. No vortex effect is generated and the orthogonal and in-phase interference are *all. In addition, no polarization will occur. These characteristics will ensure the low power consumption of flowmeter. No heat is generated and the zero is quite stable. No drift will happen and the little pollution will happen to the electrode.
Intelligentized transducer adopts clutter suppression technology to eliminate the clutter completely to ensure the stable measurement. In order to ensure the accurateness in measurement, the function magnetic field *ysis is adopted to remove bias flow. These techniques help overcome the interferences of noises from the fluids such as slurry and paper pulp to ensure the stability and accurateness in measurement. It is the greatest advantage of Floworld FFM 62 intelligentized electromagnetic flowmeter.
The electrode lead of the sensor is led out while being kept parallel to magnetic line of force. In this way, the induction current in the circuit of the electrode lead of most electromagnetic flowmeters is removed; the oxthogonal interference and zero drift that result from the unparalleli* between the electrode lead and magnetic line of force are overcome to ensure the linearity and precision of the sensor.
Excitation coil adopts the advanced NC coil winding machine. The coils are automatically controlled through the use of PLC. For the already wound excitation coil, it will be treated with special technology to ensure the constant and uniform magnetic field as well as the repeatability and interchangeability of the sensor, thus ensuring the good precision, linearity and repeatability of the sensor.
