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.
The core content of the Chinese manual for TDS-100P portable ultrasonic flowmeter is as follows:
1. Product Overview TDS-100P portable ultrasonic flowmeter is a high-precision, non-contact flow measurement instrument suitable for measuring the flow rate of liquids in closed pipelines.
. It adopts the principle of ultrasonic time difference method, which calculates the flow velocity by measuring the time difference between the forward and backward propagation of ultrasonic waves in the fluid, and then obtains the flow rate value. This product has the advantages of easy installation, accurate measurement, and good stability, and is widely used in fields such as petroleum, chemical, water conservancy, and environmental protection.2. Main functional features: High precision measurement: The measurement accuracy can reach ± 1%, and the repeatability is better than ± 0.5%, meeting most industrial measurement needs.
. Non contact measurement: No need to damage the pipeline, easy to install, suitable for pipelines of various materials. Wide range ratio: The range ratio can reach 1:100, suitable for measurement scenarios with different flow rates. Multiple signal outputs: Supports 4-20mA current signals, RS485 communication interfaces, etc., making it easy to connect with the upper computer system. Data storage function: Built in large capacity storage, capable of storing a large amount of measurement data for subsequent analysis. Portable design: small size, light weight, easy to carry and operate on site.3. Instructions for use: Install and prepare to check whether the appearance of the flowmeter is intact and whether the accessories are complete.
. Select the appropriate sensor installation method (such as external clamp, insertion, etc.) based on the material and diameter of the pipeline. Clean the surface of the pipeline to ensure good contact between the sensor and the pipeline. When installing an external cla
