1. The k coefficient of GF9900 rotor flowmeter
Currently, there is no clear public information indicating the specific K coefficient value of GF9900 rotor flowmeter. These parameters are usually calibrated by manufacturers based on specific models, measuring media, and range. It is recommended that you directly consult the equipment manual or contact the manufacturer for the most accurate data. 1. Definition and Importance of K Coefficient K coefficient is the core parameter of a rotor flowmeter, representing the frequency of the pulse signal emitted by the flowmeter when a unit volume of fluid passes through. It is directly related to the accuracy of flow measurement, usually determined by the manufacturer through real flow calibration before leaving the factory.
2. The way to obtain the accurate K coefficient is to obtain the exact K coefficient of the GF9900 flowmeter in your hand. The most reliable method is to consult the product manual, and the parameters are usually recorded in the technical specifications section.
; Check the equipment nameplate, important parameters are often directly marked on the flowmeter body; If none of the above methods can be found, it is recommended to directly consult the manufacturer or supplier of the equipment, providing specific models and factory numbers for accurate technical support. 3. The key factors affecting the K coefficient are worth noting that the K coefficient is not fixed. It will be affected by factors such as the measurement medium (density and viscosity of different fluids), operating temperature and pressure, and the installation posture of the flowmeter itself. Therefore, it is crucial to strictly adhere to the working conditions provided by the
2. GF flowmeter settings
GF flowmeter 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, and then use the directional keys to select and modify the flow unit3. 4-20mA range setting. Set the range corresponding to 4mA and 20mA according to actual needs
4. Other parameter settings include the selection of instantaneous flow and cumulative flo
