Products Description
Natural gas Nitrogen gas flow meter with controller Digital 4-20 mA RS485 gas turbine flow meter
Gas turbine flow meters are mainly used for measuring the flow rate of medium fluids such as air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam, etc. in industrial pipelines. When measuring the volumetric flow rate under working conditions, they are almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time.

FAQ
Gas turbine flowmeter in the process of use will inevitably encounter some common failures
in response to these failures, flowmeter manufacturer Qingtian instrument for you to make common failures and solutions.
Fault phenomenon 1: There is flow through, but the instantaneous flow of the gas turbine flowmeter is zero.
Fault analysis and solution:
1, wiring error, check the gas turbine flowmeter wiring.
2. The internal parameters of the gas turbine flowmeter have been modified. Please check the instrument parameters according to the verification certificate.
3, the signal acquisition coil is damaged, affecting the transmission of the signal, even if there is traffic through the signal can not be transmitted to the converter. Slide the outer wall of the signal acquisition coil with a magnetic screwdriver. If no flow is displayed, the signal acquisition coil is damaged.
4, the medium is too dirty, the filter is blocked.
5, the impeller may be stuck, please check the impeller.

4, the medium is too dirty, the filter is blocked.
5, the impeller may be stuck, please check the impeller.
Fault phenomenon 2:
When there is no flow through the gas turbine flowmeter, the instrument has an instantaneous flow display.
Fault analysis and solution:
1, there is severe vibration in the pipeline, it is recommended to add vibration reduction measures.
2, the flow meter is not well grounded, please check the grounding.
3, there is magnetic field interference, such as frequency converter, motor, solenoid valve, etc. (on-site 50Hz power frequency interference, to a certain extent may affect the use of the instrument, the calculation of power frequency interference Q=3600k f/k,f=50Hz,k= the coefficient of the instrument. Through calculation, it can be interpreted whether there is power frequency interference in the instrument). If yes, change the installation position.
4, the flowmeter pipe stop valve is not completely closed, check the valve.

4, the flowmeter pipe stop valve is not completely closed, check the valve.
Fault phenomenon 3:
The gas turbine flowmeter is measuring normally, but the measurement value is not accurate.
Fault analysis and solution:
1, there are problems with the internal parameters of the flow meter, please check the instrument parameters according to the verification certificate.
2, instrument pressure display abnormal, please check the pipeline pressure.
Fault phenomenon 4:
Fault analysis and solution:
1, there are problems with the internal parameters of the flow meter, please check the instrument parameters according to the verification certificate.
2, instrument pressure display abnormal, please check the pipeline pressure.
Fault phenomenon 4:
The gas turbine flowmeter is measured normally, the on-site liquid crystal display is normal, and the current
output of the flowmeter is incorrect.
Fault analysis and solution:
1. Detect the on-line value in the flowmeter parameters to see whether the instrument range is the same as the upper limit of the range marked on the instrument nameplate. (Temperature and pressure compensation type is variable upper limit)
2, the flow meter current output chip is damaged.
