2. Are there any requirements for the insertion depth when installing the Cologne ultrasonic flowmeter?
There are clear requirements for the insertion depth of the probe when installing the Cologne ultrasonic flowmeter, and it must be strictly operated according to the specifications. 1 The determination of insertion depth is mainly determined by the diameter of the pipeline, and the larger the diameter, the deeper the insertion depth. Small pipe diameters (such as below DN100) are usually inserted by a few centimeters, while large pipe diameters (such as above DN1000) may need to be inserted by more than ten centimeters or even deeper.
2. Core installation requires that the probe must reach a stable flow velocity area near the center of the pipeline to ensure that the average fluid flow velocity is captured. Insertion too shallow or too deep can cause measurement errors and even damage to the sensor. 3. Specific operating specifications vary depending on the insertion depth of different models, and the installation manual provided by the manufacturer must be strictly followed. Cologne will provide specific insertion depth values, calculation formulas, or installation positioning templates for each model. Special tools should be used for accurate positioning during installation, and signal strength and quality indicators should be used to verify whether the installation position is qualified after installation.
