1. Schematic diagram of installation method for external clamp type ultrasonic flowmeter
Schematic diagram and explanation of installation method for external clamp type ultrasonic flowmeter The installation methods for external clamp type ultrasonic flowmeter mainly include V method, Z method, N method, and W method. The following are schematic diagrams and detailed instructions for each installation method:
1. V-method installation V-method installation is a relatively standard installation method for external clamp ultrasonic flow meters, which is easy to use and accurate in measurement. During installation, the two sensors need to be aligned horizontally, with their centerlines aligned with the axis of the pipeline. The measurable range of pipe diameter is between DN15 and DN400mm.
2. Z-method installation: When the pipeline is very thick or due to suspended solids in the liquid, thick scaling on the inner wall of the pipeline, or thick lining, the V-method installation signal is weak and the machine cannot work normally, the Z-method installation needs to be selected.
. The characteristic of Z-method is that ultrasonic waves are directly transmitted in pipelines without reflection (known as single acoustic path), and the signal attenuation is small. The Z-method installation can measure pipe diameters ranging from 100mm to 6000mm. When installing on site, it is recommended to use the Z-method for pipes larger than 200mm.3. N-method installation The characteristic of N-method installation is to improve measurement accuracy by extending the ultrasonic transmission distance.
. When using the N method for installation, the ultrasonic beam reflects twice in the pipeline and passes th
Fourth, W-method installation also improves the accuracy of small pipe diameter measurement by extending the ultrasonic transmission distance.
. The W method installation is suitable for measuring small pipes below 50mm. When using the W method for installation, the ultrasonic beam reflects three times inside the tube and passes through the fluid four times (referred to as the four acoustic paths). Summary: V-method installation: a standard installation method suitable for pipelines ranging from DN15 to DN400mm, with accurate measurement and easy use. Z-method installation: suitable for large pipelines or situations with weak signals, with low signal attenuation and a wide range of measurable pipe diameters. N-method installation: improves measurement accuracy by extending the ultrasonic transmission distance, suitable for small diameter pipelines. W method installation: Hubbi also improves measurement accuracy by extending the ultrasonic transmission distance, especially suitable for small pipes below 50mm. When installing an external clamp ultrasonic flowmeter, the appropriate installation method should be selected according to the actual situation, and the sensor installation position should be ensured to be correct to ensure the accuracy of the measurement results.2. What is the installation distance of DN500 external clamp ultrasonic flowmeter?
This distance is related to the wall thickness of the pipeline and the installation method. First, connect the probe cable to the display, then polish the pipeline and fix a probe. Then turn on the display, enter menu 91, set th
