Scale vortex flowmeter in the measurement of coke oven gas output signal is not stable what are the reasons and solutions

Abstract: scale vortex flowmeter in the measurement of coke oven gas output signal is not stable when the cause and the solution to what information is produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Also called vortex flowmeter vortex flowmeter or karman vortex street flowmeter. Comprehensive developed countries to absorb advanced technology and summarizes the research and production experience for many years on the basis of the careful design of products, realize the intelligent products, standardization, seriation, generalization. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale vortex flowmeter in coke oven gas measurement output signal is not stable when the cause and the solution to what the article details. Also called vortex flowmeter vortex flowmeter or karman vortex street flowmeter. Comprehensive developed countries to absorb advanced technology and summarizes the research and production experience for many years on the basis of the careful design of the product, realizes the intelligent products, standardization, the seriation, generalization, the production of the beautiful sex of mold, to ensure product quality. The product has advanced circuit, micro power consumption is low, than a wide range, simple structure, small resistance loss, strong and durable, widely used, long service life, stable performance, easy installation and debugging, etc. Vortex street flowmeter measurement of coke oven gas, the output signal is not stable for the following reasons: 1, the vortex street 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. 2, 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. 3, 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. 4, instrument line pressing false wiring process, resulting in intermittent transmission in the process of signal. 5, 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. Solution: 1, in the process of instrument installation, connection, shall ensure the accuracy and correctness of each link, 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. 2, for the running of the measurement 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. 3, regular to overall instrument cleaning, when necessary to purge of sensing head part of the instrument, avoid impurities in the condensation on the top of the sensor. Cold season in the straight section of measurement and instrument parts and heating device is beneficial to alleviate the impurities in the measuring instrument of condensate. 4, drainage pipe on a regular basis, especially in front of the straight pipe water vortex flowmeter, according to the specific circumstances set specialist emissions on a regular basis, as far as possible reduce the moisture in the metering section, zui big limit rule out of the fluid pulsation. 5, strengthen the management of data measuring system, set up the timing print function, according to the print data combining with the production situation analysis of the operation of the instrument. Haynes automation instrument is a company specializing in the production of electromagnetic flowmeter, turbine flowmeter, vortex flowmeter, magnetic flap liquid level meter, thermocouple, heat resistance, bimetallic thermometer and all kinds of pressure gauges, etc. , as well as the production of various non-standard meter manufacturers, the company has advanced management level, the modernization of professional production equipment, precision calibration device. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
