1. Method of flowmeter reading
The method of flowmeter reading varies depending on the type of base height, with a focus on identifying the display area and mastering the numerical calculation logic. 1. The main feature of mechanical water meters is the combination structure of pointers and numbers. The reading is divided into two steps: • Integer part: directly read the black number in the center of the dial, in cubic meters. • Decimal part: Observe the surrounding red pointers. If the pointer marked with "× 0.1" points to 5, then the decimal part is 0.5 cubic meters. The total water volume is the sum of integers and decimals, for example, the black number displays 12 and the red pointer adds up to 0.5, resulting in a total usage of 12.5 cubic meters. 2. The electromagnetic flowmeter displays data directly through the display screen, and two parameters need to be considered: • Instantaneous flow rate: reflects the current flow rate, measured in liters per minute or cubic meters per hour. Accumulated flow: Record the total flow value of the device since its activation, usually in cubic meters or liters. Jian Xiang 3 The reading of vortex flowmeter is similar to that of electromagnetic flowmeter, and the key is to identify the display panel mode: some devices switch between displaying instantaneous flow and cumulative flow through buttons. -If equipped with a temperature sensor, pay attention to whether the data interface has mixed temperature parameters. four Ultrasonic flowmeter adopts non-contact measurement, and when reading, it is necessary to ensure that the probe is firmly installed and check the instantaneous flow rate and cumulative total amount of the host. -Regularly verify the calibration status of
2. Kurz flowmeter parameter setting
The parameter setting of Kurz flowmeter (usually vortex type) needs to be strictly customized according to the working conditions. The manufacturer usually completes the basic calibration before leaving the factory, and users usually do not need to adjust it themselves.
. If you need to reset, be sure to operate under the guidance of professional personnel. 1. In the parameter menu, the preferred measurement medium (such as liquid, gas, steam) is set for the medium and compensation mode. The type of medium directly affects the flow calculation formula. If measuring variable density media such as steam, it is necessary to choose "density compensation" or "mass flow compensation" mode only rising type. Only filling in the medium type without enabling compensation will result in measurement errors.2. It is recommended to set the upper limit of the range selection at 1.2 times the maximum flow rate, and the minimum flow rate should not be lower than 10% of the full range. For example, when the actual flow range is 0.5-3m ³/h, if it is set to 0-10m ³/h, the low flow section may not be effectively detected. 3. Unit configuration flow units (such as m ³/h, L/min) and total units (such as liters, standard cubic meters) can be adjusted through password access to the parameter interface, which needs to be consistent with actual application requirements.
