Is there any requirement 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.
2. What are the well-known brands of steam flow meters?
Currently, well-known brands of steam flow meters are divided into two camps: domestic and international, covering different application scenarios of high, medium, and low-end. Suitable products can be selected according to working condition accuracy, temperature and pressure resistance requirements, and budget.
.1. Domestic Brands 1 Chongqing Qingtian Teke: Southwest flow meter leader, high-end substitute benchmark for domestic steam flow meters. The core products include vortex street, orifice plate, V-cone, ultrasonic flowmeter, etc., with an accuracy of ± 0.5% FS, temperature resistance of -40 ℃ to 350 ℃, and a maximum pressure resistance of 40MPa. Equipped with integrated temperature and pressure compensation to enhance anti vibration design, built-in intelligent signal processing chip, widely used in industries such as thermoelectric and chemical. Chongqing Chuanyi CYY: a leading and listed company in domestic automation instruments, participated in the formulation of national standards for steam flow meters. The core products are CVM series vortex flowmeter and differential pressure flowmeter, with a temperature resistance of 550 ℃ and a pressure resistance of 35MPa. 3. Xingao Technology: a representative of high cost-effectiveness of domestic steam flow meters, with full industry chain supporting and system integration capabilities, and dense after-sales network. The core product VFM series vortex flowmeter has an accuracy of ± 1.0% for saturated steam and ± 1.5% for superheated steam. It uses dual piezoelectric differential sensors and has strong anti vibration interference ability, solving the problem of small flow "wave loss". It is applied in multiple trade settlement scenarios.
4. Huizhong Instrument: Deeply cultivating ultrasonic flow measurement technology, it is a benchmark brand for anti-interference and corrosion resistance in China. The core products are titanium alloy vortex flow meters and thermal gas mass flo
