What is the reason for the difference in displayed values between the vortex flowmeter and the accumulator?
There may be several reasons why the displayed values of the vortex flowmeter and the integrator are different.
1. Calibration differences: The vortex flowmeter and the integrator may have undergone different calibration processes, and there may be differences in calibration methods and standards.
. This may lead to differences in measurement range or accuracy between the two, resulting in inconsistent displayed values. Flow rate range: Vortex flowmeters and integrators may have different linear ranges when measuring steam flow rate. If the flow rate exceeds the linear range of a certain device, it may cause inconsistent display values. Fluid parameters: The measurement results of vortex flowmeters and integrators may be affected by fluid parameters such as steam temperature, pressure, or density. If the response codes of these parameters are different between the two, it may result in inconsistent displayed values. 4. Data processing algorithm: Vortex flowmeter and accumulator may use different data processing algorithms to calculate flow rate. The accuracy and calculation methods of these algorithms may vary, resulting in inconsistent displayed values. The methods to solve this problem include: 1. Calibration and adjustment: Calibrate the vortex flowmeter and accumulator to ensure they are calibrated according to the same standards and make necessary adjustments to reduce differences. 2. Determine the working range: Understand the working range of the vortex flowmeter and accumulator, and ensure that their data is consistent when used. 3. Determine fluid parameters: Confirm the temperature, p
2. Can you explain the full range measurement data of DN80 vortex flowmeter?
DN80 refers to the small flange of the vortex flowmeter, and DN80 also refers to the inner diameter of the pipeline being 80mm. From the measurement range, DN80 vortex flowmeter measures the small range of 12m3/h and the maximum full range of 120m3/h for the front body of the liquid sensing chamber. DN80 vortex flowmeter measures the small range of gas at 80m3/h and the maximum full range at 800m3/h.
3. How to adjust inaccurate gas flow meter values
The adjustment method for inaccurate gas flow meter values. The deviation of gas flow meter values needs to be adjusted according to specific types and working conditions. The following are common types and adjustment methods
1. Differential pressure flowmeter • Zero calibration: Close the upstream and downstream valves, ensure that the medium flow completely stops, and perform zero calibration through the transmitter menu (note: operate in a state of no flow and stable pressure/temperature).
. • Range adjustment: Based on actual operating parameters (design pressure, temperature, density), recalculate the theoretical differential pressure value and correct it through the transm
