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. How to calibrate a flowmeter? In practical use, if the temperature, pressure, and properties of the medium are different from the calibration time, or if the flow meter wears out significantly after long-term use, or if a non-standard flow meter is manufactured by oneself, it is necessary to calibrate the flow meter and re determine its flow coefficient or calibration curve. The calibration methods for flow meters include volume method, weighing method, standard flowmeter method, etc. Each flowmeter undergoes strict calibration and testing before leaving the factory. However, due to changes in the environment and differences in installation conditions during use, especially in the potato mold conditions where the measured medium is significantly different from the original calibration medium, the flowmeter may have corresponding indication errors during the measurement process. If it is damaged, it needs to be re calibrated. Additional information: Flow measurement is widely used in various fields such as industrial and agricultural production, national defense construction, scientific research, foreign trade, and peoples daily lives. In the production of the petroleum industry, flow measurement runs through the entire process from oil extraction, transportation, refining and processing to trade and sales. Any link cannot be separated from flow measurement, otherwise the normal production and trade exchanges of the petroleum industry cannot be guaranteed. In the chemical industry, inaccurate flow measurement can cause an imbalance in the distribution ratio of chemical components, which cannot guarantee product quality and can even lead to production safety accidents. The measurement and regulation of the flow rate of liquid, gas, steam and other media play an important role in the production of the power industry. According to the most popular and widely used classification, it can be divided into volumetric flow meters, differential pressur
