Henan Airlines Traffic Instrument Co., Ltd. the XFE Series Intelligent Electromagnetic flowmeter About 
 Henan Airlines Traffic Instrument Co., Ltd. XFE series of intelligent electromagnetic flowmeter used to measure conductive fluid flow of tap water, iron and steel, petroleum, chemicals, electricity, industry, water conservancy and other departments can also measure the acid, alkali, salt and other corrosive conductive liquid . First, the XFE series of intelligent electromagnetic flow meter operating principle 

 Faraday induction law (referring to is when the conductor through a magnetic field in the conductor internal EMF) is the basic principles of electromagnetic flowmeter. This measurement principle can be applied to the conductive fluid, the fluid flow into the magnetic field perpendicular to the direction of flow of the pipeline, the potential generated in the fluid sensor can make use of the symmetrical arrangement of two electrodes to measure. Signal voltage UE and the magnetic induction B, the electrode spacing D and the fluid is proportional to the average velocity V. Magnetic induction B and the electrode spacing D is constant, the signal voltage UE and the average flow velocity V is proportional to. That the signal voltage UE and the volume flow rate is linearly proportional to the equation used to calculate the volumetric flow rate. The induced signal voltage is converted to the indexing of the converter, analog and digital output signal. XFE series of intelligent electromagnetic flow meter Product Features 
 No moving parts in the pipeline, the unimpeded flow of parts, measuring almost no additional pressure loss. Measurement results and the velocity distribution, independent of fluid pressure, temperature, density, viscosity and other physical parameters. 
 Bi-directional measurement system can measure forward and reverse flow. 
 At the scene, according to the actual needs of users online modify range. Measurement of straight pipe required for a shorter, easy to install; measurement tube with no moving parts, long life sensor. SMD devices and surface mount (SMT) technology, circuits, high reliability, low power consumption. 16-bit embedded microprocessors, computing speed, high precision, programmable frequency square wave low frequency excitation, the stability of the flow measurement. Full-digital processing, anti-interference ability, reliable measurement. 
 Sensor induced voltage signal to a linear relationship between the average velocity range than the width 1:1500. The ultra low-power EMI switching power supply for the power supply voltage range, good EMC performance. Three totalizer, there were positive cumulative and reverse cumulative totalizer and the difference between the internal power-down clock, and can record 16 power-down time. Convenient applicable, after installation, just plug in the power, without any other action to the standard signal output, to facilitate the use of non-professionals. RS485, RS232, Hart, Modbus and Profibus digital communication signal output.
