1. What does K-factor mean? K-factor, also known as K value, is a fixed coefficient obtained by comparing and calibrating measuring equipment that meets the accuracy requirements before the instrument is put into operation. The determination of this coefficient is based on the specific calibration situation of each instrument, rather than the preset values during the design phase. Its main function is to ensure the accuracy and reliability of flow meter measurement data. Specifically, the process of obtaining K values involves multiple steps. Firstly, select a high-precision measuring device as the standard, and then compare the flow meter to be verified with the standard measuring device for measurement. After multiple measurements and recording of data, the K value is calculated through data analysis. This coefficient can correct the difference between the measured results of the flowmeter and the actual values, making the measurement results more accurate. For flowmeter manufacturers, K value is an important indicator to ensure product quality. By accurate calculation and verification, ensure that each factory worn flowmeter has an accurate K value. This not only helps to increase user trust, but also effectively avoids economic losses and security issues caused by measurement errors. It is worth mentioning that the K value is not constant. In practical applications, due to changes in environmental conditions such as temperature, pressure, and other factors, the performance of flow meters may be altered, thereby affecting the K value. Therefore, it is necessary to regularly calibrate and recalculate the K value of the flowmeter to ensure the accuracy of its measurement results. In summary, the K value plays a cruc_600x400.jpg)
2. What are the types of mass flow meters
3. GF flow meter settings
GF flow meter settings mainly include flow calibration (K coefficient setting), unit adjustment, 4-20mA range setting, and other parameter settings.
. 1. Flow calibration (K coefficient setting) The K value is a key parameter that represents the conversion coefficient of the flowmeter and directly affects the accuracy of the measurement results. When setting the K value, it is necessary to refer to the user manual and relevant technical information of the flowmeter, and select the appropriate K value based on the model and specifications of the flowmeter, as well as the type and state of the fluid to be measured (such as liquid, gas, temperature, pressure, etc.). The calculated or selected K value can be input into the flow meters settings interface through the flow meters control panel or specialized configuration software. On the GF 9900 transmitter, press and hold the Enter key for 3 seconds, then select CAL and press Enter to enter. Adjust the KF value by right clicking in the direction until it matches the calculated K coefficient. Finally, press Enter to save the settings. 2. Unit adjustment: Choose the appropriate flow unit according to actual needs, such as cubic meters per hour (m ³/h), liters per minute (L/min), gallons per minute (GPM), etc. On the GF 9900 transmitter, the specific steps for unit adjustment are: press and hold the Enter key for 3 seconds, then select INPUT to enter, a
