Abstract: the vortex flow meter scale coke oven gas measurement unstable reason and solution to the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex flowmeter is an extremely versatile flow meter, can be used in almost all gas, liquid and steam flowmeter measurement and control, a new generation of digital intelligent vortex flowmeter, it breaks through the traditional analog approach to the limits of the vortex signal, through. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale coke oven gas measurement unstable reason and solution article details. Vortex flowmeter is an extremely versatile flow meter, can be used in almost all gas, liquid and steam flowmeter measurement and control, a new generation of digital intelligent vortex flowmeter, it breaks through the traditional analog approach to the limits of the vortex signal, through the modern digital signal processing method of vortex sensor signal identification, screening, to get the normal traffic signals, greatly improve the seismic behavior of the vortex street, fundamentally solves the problems surrounding the vortex for decades is not the earthquake, it is widely used in petroleum chemical industry, light industry, thermal power, the papermaking industries such as water supply, to salt, to the wind flow. According to the practical experience, the vortex street flowmeter measurement of coke oven gas, the output signal is not stable for the following reasons: 1, instrument grounding line do not conform to the requirements of the specification, so that the high voltage of 50 hz interference, when the normal signals is higher than the normal output at 50 hz, the opposite will output error signals. 2, due to the impurities of coke oven gas, easy to crystallization, condensation of impurities in the sensing head, causing metering phrase. At higher temperatures, volatile impurities, increased sensitivity, signal enhancement; Opposite to reduce. Resulting in the data is not stable. 3, coke oven gas as the factory when the temperature is high, the humidity is big, so the water in the process of gas transmission will exist. Gas flow reciprocating drive moisture fluctuations, thus forming a pulsating flow. Vortex flow sensor output data in this fluid state large and small, cannot reflect the status of production. 4, instrument line pressing false wiring process, resulting in intermittent transmission in the process of signal. 5, vortex flowmeter is not suitable for installation in strong vibration occasions is widely known as carriers, but in the case of magnetic field changes frequently, vortex flow sensor can measure the signal output of higher than normal. Practice has proved that in the absence of the gas flow field, when the vortex flow sensor in the change of magnetic field at the instant of the magnetic field changes, vortex flow sensor can sense if a wrong signal and output, when change over, instrument in a steady magnetic field, the instrument will output a normal signal. Solution: 1, to run in the measuring system can be used & other; Contrast to confirm & throughout; Methods, as well as & other; Alternative method & throughout; To identify and eliminate running measuring instrument malfunction. 2, in the process of instrument installation, connection, should ensure that every link of the accurate, including before installation on the investigation to the scene, the installation process instrumentation wiring, system grounding line, etc. , to ensure that the real data and be able to accurately detected output.
