Lu series vortex flowmeter parameter settings

Project Overview

　　Vortex flowmeter is widely used in industries such as petroleum, chemical, power, metallurgy, etc. due to its high accuracy, wide range ratio, and low pressure loss. As a commonly used intelligent flowmeter, the parameter settings of the LU series vortex flowmeter directly affect the measurement accuracy and stability. This article will provide a detailed introduction to the parameter setting method of the LU series vortex flowmeter, to help users better use the instrument.

　　1、 Overview of LU series vortex flowmeter

　　The LU series vortex flowmeter is based on the Karman vortex principle. When the fluid flows through the generator, the frequency generated alternately on both sides is proportional to the flow velocity. The volumetric flow rate of the fluid can be calculated by detecting the frequency. This series of flow meters adopts microprocessor technology, which has the characteristics of high accuracy, strong reliability, and intuitive display.

　　2、 Preparation work before parameter setting

　　Before setting parameters, the following preparations need to be made:

　　Carefully read the user manual of the LU series vortex flowmeter to understand the performance parameters, functional characteristics, and precautions of the instrument. Prepare the necessary tools for setting parameters, such as handheld devices, upper computer software, etc. Ensure that the flow meter is correctly installed and powered on. Record relevant information on the flowmeter nameplate, such as model, range, medium, etc. 3、 Main parameter settings of LU series vortex flowmeter

　　The main parameter settings of the LU series vortex flowmeter include the following aspects:

　　1. Fluid parameter settings

　　The fluid parameter settings mainly include medium type, density, viscosity, etc. Under different media and working conditions, the physical properties of fluids may vary, so it is necessary to set them according to the actual situation. For example, selecting the medium type as "liquid" or "gas", inputting the density and viscosity values of the medium, etc.

　　2. Pipeline parameter settings

　　The pipeline parameter settings mainly include pipeline diameter, pipeline material, lining material, etc. Pipeline parameters can affect the flow state of fluids, so accurate settings are required. For example, enter the numerical value and unit of the inner diameter of the pipeline, select the pipeline material as "carbon steel" or "stainless steel", etc.

　　3. Measurement parameter settings

　　The measurement parameter settings mainly include measurement range, display unit, small signal cutoff, etc. The measurement range should be set according to the actual flow rate to ensure measurement accuracy. The display unit can be selected from "m ³/h", "L/min", etc., making it convenient for users to read data. The small signal cutoff function can filter out signal interference at low flow rates and improve measurement stability.

　　4. Output parameter settings

　　The output parameter settings mainly include output signal type, output range, alarm settings, etc. The LU series vortex flowmeter usually provides multiple output signal types, such as 4-20mA, 0-5V, pulse, etc., and users can choose according to their needs. The output range should match the input range of the subsequent instrument or control system. The alarm setting can set the upper and lower limit alarm values of the flow according to the actual working conditions.

　　5. Other parameter settings

　　In addition to the main parameters mentioned above, the LU series vortex flowmeter also provides some other parameter settings, such as communication parameter settings, display parameter settings, system parameter settings, etc. Users can make settings according to their actual needs to achieve more functions.

　　4、 Parameter setting method

　　There are two main methods for setting the parameters of the LU series vortex flowmeter:

　　1. Handheld device settings

　　The LU series vortex flowmeter is usually equipped with a manual controller, which can be used to set parameters through the buttons and display screen on the controller. Please refer to the instrument manual for specific operating steps.

　　2. Upper computer software settings

　　Users can communicate with the LU series vortex flowmeter through the upper computer software and set parameters using the software interface. The upper computer software usually provides more intuitive and convenient parameter setting functions, as well as data recording, analysis, and other operations.

　　5、 Precautions for parameter settings

　　When setting the parameters of the LU series vortex flowmeter, the following points should be noted:

　　After the parameter settings are completed, they should be verified to ensure the accuracy of the settings. During the operation of the flowmeter, it is necessary to regularly check whether the parameter settings are correct and adjust them according to the actual situation. If encountering parameter setting issues, it is necessary to promptly contact the manufacturer's technical personnel for resolution. 6、 Conclusion

　　The parameter settings of the LU series vortex flowmeter are crucial for ensuring the measurement accuracy and stability of the instrument. This article provides a detailed introduction to the parameter setting methods and precautions of the LU series vortex flowmeter, hoping to be helpful to users. In practical applications, users should set parameters according to specific situations, and carry out parameter verification and maintenance work
