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 small. 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 analysis 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 unparallelism 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.
