The core advantages of domestic ultrasonic flowmeter first tier brands are technological independence and wide application, forming leading camps such as Wofei Kai, Huizhong, Tiangang Instrument, etc. 1. Brand structure and technological advantages
(1) WOFK, a British technology background enterprise, independently develops high-performance ultrasonic sensors with a measurement accuracy of ± 0.5%. The adaptive multi-channel measurement technology significantly improves the adaptability to complex working conditions. The product line covers types such as external clamping and insertion, and is widely used in high demand fields such as petroleum and chemical engineering.
(2) Huizhong HUIZHONG is the benchmark for domestic ultrasonic flow measurement and the first household ultrasonic heat meter to break the foreign monopoly.
. Its products have outstanding performance in the civilian field, with drip level precise measurement technology effectively solving the problem of detecting small flow rates, and its reputation covers industrial and daily scenarios.(3) Tiangang Instruments is deeply involved in the field of IoT ultrasonic measurement, with a leading market share in China. As the only domestic enterprise that has passed the MID certification for large caliber ultrasonic flow meters in Germany, our products have been exported to more than 20 countries, and our technology has obvious global characteristics. 2. We have the ability to adapt to specific scenarios. 4. Huaian Runzhong Instrument optimizes the measurement performance of complex working conditions based on intelligent algorithms, and the combination of sensing technology and data processing capabilities enhances the stability of the instrument, making it suitable for high dynamic scenarios such as water conservancy monitoring.
(5) Tianxin Instrument TANCY specializes in the field of gas flow measurement. The TUS type flowmeter achieves high-precision gas measurement through multi-channel layout, and adapts flexible communication protocols to meet the monitoring needs of energy industries such as gas and petrochemical.
.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 accura
