The working principle of the electromagnetic flowmeter

Electromagnetic flowmeter structure: the structure of the electromagnetic flowmeter is mainly composed of magnetic circuit system, measure the catheter, electrode, shell, lining and converter and other parts. Electromagnetic flowmeter features 1, measured from the fluid density, viscosity, temperature, pressure and the influence of the conductivity changes; 2, measuring pipe unimpeded flow components, no pressure loss, low straight pipe requirements. To measure serum has a unique adaptability; 3 lining and electrode material, the reasonable choice sensor, which has good corrosion resistance and wear resistance; 4, converter adopts novel excitation method, low power consumption, zero point stability, high precision. Flow range up to 150:1; 5, converter and sensor type or separation of a size; 6, converter adopts 16-bit high-performance microprocessors, 2 x16lcd display, parameter setting is convenient, reliable programming; Within 7, flow meter to measure the size of the system, two-way three integrator: forward, reverse the amount and total difference amount; Forward and reverse flow can be shown, and has a variety of output: current, pulse, digital communications, HART; 8, converter using surface mount technology ( SMT) With self-check and self-diagnosis function; 9, the measuring accuracy is not affected by fluid density, viscosity, temperature, pressure and conductivity changes, the influence of sensor induction voltage signal, and a linear relationship between the average flow, so the measurement precision is high. 10 shine, measuring the pipe flow, so there is no additional pressure loss; Measurement of the pipe have no moving parts, so very long sensor life. 11, due to the induced voltage signal is formed in the whole space full of magnetic field, is the load average on the surface of the pipe, so the sensor for short straight pipe, the length of 5 times the pipe diameter. 12, converter adopts the most advanced international latest MCU ( MCU） And surface-mount technology ( SMT) , reliable performance, high precision, low power consumption, stable zero, parameter setting is convenient. Click on the Chinese display LCD, display cumulative flow, instantaneous flow rate and flow velocity, flow percentage, etc. 13, two-way measurement system, the measurable positive flow, reverse flow. The use of special production technology and high quality materials to ensure product performance is stable in a long time. Simple installation method of electromagnetic flowmeter is composed of flow sensor transmitter. Electromagnetic flowmeter installation requirements must be installed in the bottom of the pipe or line of vertical section, but must be under the condition of the full package, requirement for straight pipe is a former 3 d after 5 d, so as to ensure the use of electromagnetic flowmeter and the requirement of accuracy. Electromagnetic flowmeter measurement principle is not dependent on the characteristics of the flow, if the line has some turbulence and vortex in the measurement area ( Such as elbow, tangential current limiting or upstream of half cut-off valve) Has nothing to do with the measurement. If there is a steady state of the eddy current in the measurement zone will affect the stability of measurement and measurement precision, then you should take some measures to stabilize the velocity distribution: 1. Increasing the length of the straight pipe before and after 2. Using a flow stabiliser 3. Reduce the cross section of measurement point. Meter should avoid installed in high temperature radiation temperature changes a lot, or by equipment, if must be installed, must be backed by a heat insulation, ventilation measures. Flow meter installed in indoor best, if must be installed in the outdoor, should avoid the rain pouring, water flooded and the sun insolates, must have moistureproof and sun protection. Flowmeter installation should be avoided in the containing corrosive gas environment, must be installed, ventilation measures shall be required. In order to convenient installation, maintenance, maintenance, around the flow meter need to have ample installation space. Flowmeter installation site should avoid to have a strong magnetic field and the vibration source, such as the pipeline vibration, bearing of the pipeline in flow meter should be fixed on both sides.
