1. Selection of Kelon flowmeter
Kelon electromagnetic flowmeter selection is mainly based on four core parameters: flow range, pipe diameter, medium characteristics, and environmental conditions. If referring to the German brand Krohne, additional attention should be paid to its technological advantages and application scenarios. 1. The selection of Kelon electromagnetic flowmeter should be based on the bending point and flow range: select the corresponding specifications and models according to the medium flow rate to ensure accurate measurement. • Pipe diameter and liquid adaptation: Supports DN6-DN3000 pipe diameters, and needs to match the size of the on-site pipeline. • Medium conductivity: The medium conductivity is required to be greater than 5 μ S/cm, and both liquids and gases can be measured. • Environmental adaptability: Factors such as temperature, humidity, and vibration need to be considered when selecting the corresponding housing material.
2. Krohne flowmeter from Germany has special advantages. • Technical features: The vortex flowmeter adopts the Karman vortex principle, with PTFE lining corrosion-resistant and an accuracy of ± 0.5%, suitable for high flow fluctuation conditions in the chemical industry. Customized service: Provide caliber and material adjustments based on the viscosity, corrosiveness, and other characteristics of the medium. • Industry application: Long term service to companies such as BASF and Bayer, specializing in measuring corrosive fluids.
3. Selection precautions - If the medium has low conductivity (<5 μ S/cm), other principle flow meters (such as vortex street, ultrasonic) should be selected.

2. Which model of instrument amplifier is used in the Cologne electromagnetic flowmeter?
The instrument amplifier model used in the Cologne electromagnetic flowmeter is AD8228.
. Regarding the core characteristics of AD8228, as a precision instrument amplifier, its role in electromagnetic flow meters is particularly crucial. It accurately amplifies the weak signal output by the sensor by suppressing common mode voltage interference, ensuring the stability and reliability of flow data. two The design details of the performance advantage AD8228 adopt laser adjustment resistance technology, effectively controlling gain error (annual rent ± 0.05%) and gain drift (± 5ppm/℃). In terms of circuit layout, its optimized design has achieved a common mode rejection ratio (CMRR) of over 120dB, significantly improving anti-interference capability. three The key capability of adapting electromagnetic flow meters is that this device supports a wide power supply range (± 2.3V to ± 18V) and is suitable for the complex and demanding power supply needs of industrial environments. Its wide operating temperature range (-40 ℃ to+125 ℃) is highly compatible with the common working scenarios of electromagnetic flowmeters, and is suitable for measuring various media with changes in liquid conductivity.3.
