1. How to read the scale of a flow meter? The scale of a flow meter can be viewed from the pointer, and only a four pointer flat flow meter has a scale, which can clearly record the flow rate per hour.

3. Flow meter reading methods

Flow meter reading methods vary depending on the type of base height, with a focus on identifying display areas and mastering 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 Ultra Pointer flowmeter

sonic 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 equipment to avoid errors caused by differences in pipeline material or fluid density. After understanding the characteristics of different types of flow meters, the key calibration scale data module can be quickly located during operation to avoid misreading or missing readings.

4. How to view the scale of the flowmeter

The way to view the scale of the flowmeter needs to be operated according to the type, and the key point is to find the reading reference point (such as the upper edge of the rotor or pointer) or directly read the data on the display screen.

. 1. Appearance features of glass rotor flowmeter: The vertical conical glass tube is equipped with a rotor that can float up and down, and there are scale markings on the outside of the tube. Operation focus: Keep your line of sight level with the upper edge of the rotor, and read this scale value, usually in L/h or m ³/h. This method can reduce errors caused by looking up or down. two Appearance features of metal tube float flowmeter: The metal shell protects the internal structure, and the surface is equipped with a circular dial and pointer with scales. Operation focus: Directly observe the scale value pointed by the pointer tip, and the range and unit (such as 0-100m ³/h) will be marked on the outer edge of the dial. No conversion is required when reading. three Appearance features of electromagnetic flowmeter: No mechanical moving parts, real-time flow data is displayed through LCD/LED display scre
