The following is the article details of the reasons for the instability of coke oven gas measured by vortex flowmeters and their solutions. Vortex flowmeter is an extremely versatile flow meter, which can be used in almost all gas, liquid and steam flowmeter measurement and control. The new generation of digital intelligent vortex flowmeter breaks through the traditional analog way to process vortex signals. The limitations of the vortex street probe are identified and screened by modern digital signal processing methods, so as to obtain a normal flow signal, which greatly improves the seismic performance of the vortex street, and fundamentally solves the problem that the vortex street has not been seismically resistant for decades. It is widely used in the flow of water supply, salt supply and air supply in petrochemical, light industry, thermal power, papermaking and other industries. According to practical experience, when the vortex flowmeter measures coke oven gas, the reasons for the unstable output signal are as follows: 1. The ground wire of the instrument does not meet the requirements of the specification, so that the 50Hz interference in the strong electricity enters. When the normal signal is higher than At 50Hz, the normal signal will be output, otherwise, the error signal will be output. 2. Because coke oven gas has many impurities, it is easy to crystallize, and the impurities condense on the sensing head, resulting in measurement inaccuracy. When the temperature increases, the impurities volatilize, the sensitivity increases, and the signal increases; on the contrary, it decreases. This results in data instability. 3. The coke oven gas has high temperature and high humidity when it leaves the factory, so there will be moisture in the gas transportation process. The gas flow drives the water to fluctuate back and forth, thus forming a pulsating flow. When the vortex flow sensor is in this fluid state, the output data fluctuates, which cannot reflect the production status at all. 4. The pressure line is not solid during the wiring process of the instrument, which causes the intermittent signal during the transmission process. 5. It is widely known by users that the vortex flowmeter is not suitable to be installed in the occasion of strong vibration, but in the occasion of frequent changes of the magnetic field, the vortex flowmeter will measure the signal output higher than the normal value. Practice has proved that in a field without gas flow, when the vortex flow sensor is in a changing magnetic field, at the moment when the magnetic field changes, the vortex flow sensor will sense an error signal and output, when the change is over, the instrument is in a stable magnetic field. , the meter will output a normal signal. Solution: 1. For the measurement system in operation, it can be used“Compare and confirm”method, and“Alternative method”Confirm and eliminate the faults of the measuring instruments in operation. 2. In the process of instrument installation and connection, it is necessary to ensure the accuracy of each link, including the inspection of the site before installation, instrument wiring during installation, system grounding, etc., so as to ensure that the real data is detected and can be accurately output. .
