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. How to calibrate GF8550-1 rotor flowmeter ɘ
After installing the flowmeter, let the pipeline fluid be transported normally. It is best to circulate only when the fluid is not in use, so that the actual flow rate is as stable as possible. The panel will display a flow rate value, but it is uncertain whether it is consistent with the actual flow rate. The following is the calibration. Find another calibrated flow meter (usually using a calibrated handheld ultrasonic flow meter with dates, how to use it is not much discussed about inspection and disassembly), measure the actual flow rate in the pipeline, compare it with the GF panel, and if the display is inconsistent, adjust your GF flow meter by following the steps below (the up key is simply called up, the down key is simply called down): Press and hold the "ENTER" key for 2 seconds to enter the calibration interface (dont press it too long, 5 seconds will enter the operation interface, if you need a password, the default is "up, up, down"). Press up or down to find "FLOW K-FACTOR", adjust the value of this item, and then hold down both the up and down buttons to save and exit (of course, you dont know how many FLOW K-FACTOR settings you need to set, so you need to enter several times and adjust according to the value you set and the changes in flow rate). When the flow value is adjusted to match the value of the other flowmeter, record the FLOW K-FACTOR value. Go back to the calibration interface and find TOTALL K-FACTOR. Set the value to match the FLOW K-FACTOR, save and exit. FLOW K-FACTOR is a parameter for real-time traffic, while TOTALL K-FACTOR is a parameter for cumulative traffic.
