1. What are the parameters of a mass flowmeter and how to adjust them? The main parameters of a mass flowmeter include measurement range, accuracy, repeatability, linearity, and response time. Adjusting the parameters of the mass flow meter can be done in the following ways: Adjusting the flow range: Manual adjustment: It can be set through the buttons or knobs on the instrument panel, and the appropriate parameters need to be determined based on the actual flow range. Automatic adjustment: Utilizing the built-in automatic adjustment function of the mass flow meter, this function can automatically adjust parameters according to the actual flow rate, which is more convenient and fast. Adjustment accuracy: Accuracy is affected by multiple factors such as the instrument itself, sensors, and later data processing. For high-precision measurement requirements, choose a mass flowmeter with higher accuracy and adjust the parameters to the optimal state. For general applications, adjust to the accuracy that meets the actual requirements. Setting environmental parameters: The environmental parameter Hui Ying number of the mass flowmeter will affect the measurement accuracy and stability. When adjusting parameters, it is necessary to set corresponding environmental parameters to ensure the accuracy of measurement results. Attention: Adjusting the parameters of the quality flow meter requires a certain level of technical experience and professional knowledge. If unfamiliar, please have an assistant technician debug it. 2. What are the calibration parameter standards for flow meters in atomization scenarios?
The calibration parameter standards for flow meters in atomization fields need to be classified according to
1. Industrial atomization scene: Taking electromagnetic flowmeter as an example (1) Basic parameters: 1 The measurement of pipeline diameter must strictly match the actual inner diameter of the pipeline; 2. The flow unit can be selected as needed, such as m ³/h, L/s, etc; 3. The range setting should be combined with the actual flow range to avoid insufficient measurement accuracy of low flow caused by a range that is too large, and triggering an over limit alarm if it is too small. （2） Advanced parameter 1 Excitation mode: Small caliber instruments can choose 1/16 power frequency range, while large caliber instruments are recommended to choose 1/20 or 1/25 power frequency range; 2. Small signal cutoff function: It is recommended to set the cutoff point to 0-5% of the range, and you can choose whether to synchronize the cutoff display and signal output according to your needs; 3. Air traffic control alarm threshold: set at 3-5 times the measured conductivity; 4. Reverse output permission function: can be flexibly activated according to actual process requirements; 5. Measurement of damping time: adjustable between 1-64 levels, long damping is suitable for pulsating flow accumulation scenarios, short damping responds faster and adapts to process control requirements.
