How does a rotor flowmeter read?

How to read a rotor flowmeter? The reading method is usually pointer reading, but there are also LCD readings. Pointer reading only reads instantaneous flow rate. For LCD, Sun Zhengmeng has instantaneous and cumulative flow rates. If there is bridge output, it can also be read from the display instrument. Reference: The intersection of the maximum cross-section of the rotor and the engraved line on the glass tube is the flow rate value. Read the markings on the surface clearly, but be aware that if the liquid is not water, and the temperature and pressure are not standard conditions, the reading should be corrected using a formula that is generally applicable.

2. How to read LZB-4 glass rotor flowmeter

The core reading method of LZB-4 glass rotor flowmeter can be summarized as "three confirmations and one Xianglv correction"

1. Confirm the medium and corresponding scale. The instrument scale may contain multiple sets of scales, and the corresponding scale should be selected according to the actual measured medium (such as water, air).

. Directly read the numerical values associated with water when using water as the medium; If the medium is different from the calibration conditions, reference should be made to the instruction manual or the conversion parameters provided by the manufacturer. 2. Observe the rotor position horizontally until it is stably suspended, and keep the line of sight level with the edge of the upper end face of the glass tube rotor. At this time, the corresponding scale value is the instantaneous flow rate value. If looking up or down is prone to visual errors, adjusting the standing height can ensure a level view. 3. Checking the

flow unit and range scale values should be combined with the unit to determine the actual value (such as L/h or m ³/h). The range of the LZB-4 model is generally 1-10L/h (water) or 0.5-5m ³/h (air). When reading, attention should be paid to whether the scale division value is within the effective range of the current range. When correcting for differences in working conditions, when the temperature and pressure of the medium deviate significantly from the calibration conditions (usually 20 ℃, standard atmospheric pressure), the formula is needed: actual flow rate=instrument reading x (actual medium density/calibration medium density) ^ 0.5. If there is a lack of physical parameters, it is recommended to obtain compensation coefficients through calibrating instruments or consulting equipment manufacturers.

3. How to read a glass rotor flowmeter

Read the scale with your eyes level with the upper plane of the rotor, starting from the 0 scale direction.

. The data read on the rotor flowmeter is instantaneous flow rate, either volumetric flow rate or mass flow rate. If it is a mass flow rate, you first convert it to a volume flow rate (unit: m3/s), and then estimate it by dividing the volume flow rate by the cross-sectional area based on the diameter of the rotor flowmeter (note: this is an estimation of early closing travel, because the cross-sectional area is not linear). The scale of the glass rotor flowmeter is calibrated by the production plant under local conditions using water and dry air as media that are close to ideal fluids. However, there are two situations where the scale value of a normal flowmeter cannot be directly used: first, when the measuring medium is not water and air, and second, when
