Les débitmètres à turbine à gaz sont souvent utilisés dans le contrôle de processus industriel ou le transfert de contrôle des flux de gaz. Le capteur de débit de turbine est une instrumentation précise et précise, des ingénieurs d'instrumentation professionnels sont nécessaires pour faire fonctionner et entretenir les débitmètres à turbine à gaz . L'article suivant énumère certains problèmes courants liés à l'utilisation des compteurs à turbines à gaz. Cela implique certains problèmes tels que l'absence de valeur d'affichage sur le débitmètre et une sortie inexacte du débitmètre. Je souhaite que cela aide les utilisateurs à obtenir le meilleur résultat de mesure précis.

Trouble |
Probable Cause |
Solution |
|
There is flow pass gas turbine sensor, but no instant flow displays on the flow meter display
|
Parameters has been changed in the flow meter display |
Modify theparameters according to Silver Automation Instruments supplied certificate along with goods. This certificate indicate flow meter factor, flow range , factory No., pressure rating information.Users can reset the correct parameters into the gas flow meter display |
|
No flow pass air flow meter, but display shows instant flow |
Stop valve not closed well |
Check the valve whether it has been closed tightly. |
|
Too much vibration in the pipe |
Take measures to decrease the shock in the flow meter pipe lines. |
|
|
Not well grounded |
Checkgrounding if it isearthling well, if not please ground well again. |
|
|
Too muchStrong electromagnetic interference, such asfrequency changer, Motor, electromagnetic valve.etc |
Judge by instant flow value (Q=3600f/k,f=50Hz,k=factor), you can see whether the gas meter has been affected by thestrong interference, ifI is indeedaffected, please re-stall the gas flow meters far away from the strong electromagnetic interference. |
|
|
Gas turbine sensor take Normal flowmeasurement but not accurate measuring result |
Temperature andpressure compensation problem(collect wrong temperature and pressure value) |
Takemeasures to detect the pipelinetemperature and pressure value and to see whether it is the same as turbine display displayed, if the temperature and pressure is not correct, the temperature sensor or pressure sensor could break down, it is recommend to send the air flow meter to factory to repair .( this is only for SGW-D series temperature and pressure compensation gas turbine flow meter). |
|
Parameters set wrong |
Modify theparameters according to our supplied certificate, users could set the wrong parameters into the gas flow metersdisplay, please modify into correct ones. |
|
|
Electrical board break down |
We recommend to send back the gas meter to factory to repair . |
|
|
Gas turbine flow meter take Normal gas flow measurement and display gas flow is also correct , but flow meter output is wrong |
Gas turbine flow meter has doneWrong wiring |
Check the turbine flow meter manual book or contact Silver Automation Instruments :technician@silverinstruments.com to obtain the correct wiring method, then correct into right wiring. |
|
Set the wrong flow range in the gas flow meter |
Check the up limit valueset in the flow meterdisplay whether itis the same as the flow meter name plate indicate, if not the same ,please modify into correct parameters. |
