Discuss how to use a vortex street flowmeter measurement scale coke oven gas

Abstract: discuss how to use scale vortex flowmeter measurement information of coke oven gas produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex flowmeter can be widely used in large, medium and small various water supply and drainage pipe, industrial circulation, sewage treatment, oil and chemical reagents and compressed air, saturation and superheated steam, gas and all kinds of medium flow rate measurement and can be applied as a flow transmitter. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a discussion on how to use scale vortex flowmeter measurement of coke oven gas article details. Vortex flowmeter can be widely used in large, medium and small various water supply and drainage pipe, industrial circulation, sewage treatment, oil and chemical reagents and compressed air, saturation and superheated steam, gas and all kinds of medium flow rate measurement and can be used as flow transducer is applied to automatic control system, the block using EEPROM to power-fail protection of cumulative flow, protection for more than 10 years. Vortex flowmeter is an extremely versatile flow meter, can be used in almost all gas, liquid and steam flowmeter measurement and control, my company's 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. Vortex flow meter in the measurement of application on coke oven gas or more, but there are some problems, say the reasons of these problems and the solution: the cause of the field measurement system malfunction can be summarized as two reasons, one is the result of the flow meter or its associated equipment. Second is a flow meter reasons, namely the flow meter is normal, or fault caused by the system and environment, it is difficult to find this kind of reason. In addition to the requirements and technical personnel must be familiar with the instrument performance, still need to have a wide range of knowledge and rich experience in the field of analysis, reasoning, various test, in order to confirm. Some failure or due to some unexpected events. The fault of the flow meter is often characterized by the output signal is not stable. 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) 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. 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 operation of the measuring system can be used & other; Dual track measurement, compared 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, if necessary, can be 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) Straight pipe drainage pipe on a regular basis, especially in front of the water, 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 ruled out of the fluid pulsation. 5) Strengthen the management of metering system data, set the timing print function, according to the print data combined with the operation of the production situation of instrument analysis. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
