1. How to adjust parameters of flow meter
Flow meter parameter adjustment operation process: Equipment: Flow meter
1. In the initial interface, you can right-click to enter the system settings menu, enter the password, press the light up left button to confirm and enter the settings system.
2、 After entering the system, you can see that there are instantaneous flow parameters in the settings menu, which can be adjusted by moving up and down and pressing the right button to enter.
3、 When entering the second level menu of instantaneous flow setting parameters and scroll width, find the scale flow setting and use the up and down keys to prepare for movement. Right click to enter the scale flow setting menu.
4、 After entering the scale flow setting item, you can set the scale flow, which is the method for modifying the range of the electromagnetic flowmeter. The function of the flowmeter is fully digital processing, with strong anti-interference ability, reliable measurement, high accuracy, and a flow measurement range of up to 1500:1. Ultra low EMI switching power supply, suitable for a wide range of power supply voltage changes, with good EMI resistance performance. Adopting a 16 bit embedded microprocessor, it has fast computing speed, high accuracy, programmable low-frequency rectangular wave excitation, improved stability of flow measurement, and low power consumption. Using SMD devices and surface mount technology, the circuit has high reliability.
2. What is a flowmeter
A flowmeter is an instrument that indicates the flow rate measured by Li Ting and/or the total amount of fluid within a selected time interval.
. Simply put, it is an instrument used to measure f
3. How to calculate flow rate with differential pressure flowmeter
Differential pressure flowmeter is a type of flowmeter, and its calculation formula is related to the relationship between differential pressure and flow rate.
. The calculation formula for differential pressure flow meters may vary depending on different principles and applications. Here are some common formulas for calculating differential pressure flow meters. 1. Fluid static pressure balance flow meter: Q=CA (Δ P/ρ), where Q is the flow rate, C is the flow coefficient, A is the cross-sectional area of the measuring tube, Δ P is the static pressure difference between upstream and downstream, and ρ is the fluid density2. Differential pressure is proportional to the square of the flow rate: Δ P ^ 2=K * Q ^ 2, where K is a constant and can be provided by the manufacturer or calibrated
3. Differential pressure is proportional to the square root of the flow rate: √ Δ P=K * √ Q, where K is a constant and can be provided by the shading manufacturer or calibrated
4. Standard orifice flowmeter: Q=(π D ^ 2/4) (2 Δ P/(ρ g)), where Q is the flow rate, D is the orifice diameter, Δ P/(ρ g) P is differential pressure, ρ is fluid density, g is gravitational acceleration
5. Standard Venturi flowmeter: Q=(π D ^ 2/4) (Δ P/(ρ gV)), where Q is flow rate, D is pipeline diameter, Δ
