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. How to read the value of a flowmeter
The reading of a flowmeter mainly depends on the numerical reading on the display screen, combined with the unit identification and instantaneous/cumulative flow status to determine the specific value.
. 1. The most common type of electronic data source display is the clustered word type, which directly reads the screen numbers: - The number with unit identification (such as m ³/h, L/min) is the current flow value - Distinguish between instantaneous flow (real-time change value) and cumulative flow (continuous accumulation value) - Multi parameter flow meters need to pay attention to the screen switching status (such as pressing a button to switch display modes) The pointer dial type is mainly used for mechanical flow meters: - Read the scale value pointed by the pointer - Combine the dial unit (such as 0-10 L/min) and multiple identification (X10, X 100) - Keep facing the dial to avoid parallax error 3 Common Unit Potato Stove Identification - Volume Flow Rate: m ³/h (cubic meters/hour), L/min (liters/minute) - Mass Flow Rate: kg/h (kilograms/hour), t/h (tons/hour) - Special Medium: Nm ³ Hail Hand Cherry/h (standard cubic meters/hour, for gas) 4 Operation precautions - Do not touch sensors or regulating components during operation - Electronic type attention to abnormal alarm codes (such as E01, which usually indicates sensor failure) - High pressure pipeline flow meters must read
