What does the precision level of LZB-3WB flowmeter mean? LZB-3/LZB-3WB glass rotor flowmeter is used to measure the instantaneous flow rate of single-phase non pulsating liquids and gases in pipelines. The commonly used Ziyou instrument series flow meters are mainly used in industrial sectors and research institutions such as chemical, petroleum, medical, fertilizer, food, sugar, paper, light industry, textile, printing and dyeing, and environmental protection. The accuracy level is the percentage accuracy of the flow meter scale to the full range. Its characteristics include low pressure loss, reliable performance, convenient and intuitive reading. The structure is simple, easy to install and use, and the price is cheap. The glass rotor flowmeter is a variable area flowmeter, mainly consisting of a vertically installed lower small and upper large conical glass tube and a float that can move up and down inside the tube. When the fluid flows through the conical glass tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the upward force, buoyancy, and viscous lift acting on the float are equal to the gravitational force of the floating chamber, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate passing through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a measure of flow rate. 2. How to adjust parameters of flow meter
Flow meter parameter adjustment operation process: Equipment: Flow meter
1. In the initial interface, you

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.
