Los medidores de flujo de turbina de gas a menudo se utilizan en el control de procesos industriales o en la transferencia de custodia de flujo de gas. El sensor de flujo de la turbina es una instrumentación precisa y precisa. Se requieren ingenieros de instrumentación profesionales para operar y mantener los medidores de flujo de la turbina de gas . El siguiente artículo enumera algunos problemas comunes en el uso de medidores de turbinas de gas. Implica algunos problemas, como la falta de valor de visualización en el medidor de flujo y la salida imprecisa del medidor de flujo. Desearía que ayude a los usuarios a obtener el mejor y más preciso resultado de medición.

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. |
