The following is a summary of the advantages of handheld ultrasonic flow meters:
1. Strong portability and flexible operation
Compact and lightweight in size: easy to hold or carry, suitable for on-site mobile measurement, without the need for fixed installation facilities.
Ready to install and test: No need for complex debugging, can quickly clamp or insert pipelines, suitable for temporary inspection, multi-point inspection and other scenarios.
2. Non invasive measurement (external clamp type)
Non contact with fluids: The probe is clamped on the outer wall of the pipeline to avoid direct contact with corrosive, high-temperature, or hazardous fluids, ensuring safety.
No damage to pipeline structure: No need to open holes, cut off or modify pipelines, suitable for pipelines that cannot be shut down (such as drinking water and gas pipelines).
No pressure loss: does not affect the normal flow of fluid, avoiding energy consumption increase caused by instrument installation.
3. Wide applicability
There are various types of fluids:
Time difference method: suitable for cleaning liquids such as water, oil, chemical solutions, etc.
Doppler method: applicable to fluids containing particles, bubbles, or suspended solids (such as sewage, slurry, mud, etc.).
Strong compatibility with pipe diameter: Supports pipes from small diameters (a few millimeters) to large diameters (several meters), with only the need to adjust the probe or parameters.
Flexible pipeline material: suitable for various materials such as metal (such as steel, copper), plastic (such as PVC, PE), etc. (external clamp type requires good sound transmission of the pipeline).
4. High precision and reliability
High measurement accuracy: The time difference method has an accuracy of within ± 1%, while the Doppler method typically has an accuracy of ± 2% to ± 5%, meeting most industrial measurement needs.
Strong anti-interference ability: using digital signal processing technology to reduce the impact of environmental noise and electromagnetic interference on measurement results.
Temperature compensation function: automatically corrects the impact of fluid temperature changes on sound velocity, ensuring measurement stability under different operating conditions.
5. Rich functions and convenient data
Multi parameter real-time display: It can display real-time data such as flow rate, flow velocity, cumulative measurement, sound velocity, signal strength, etc., and supports graphical interfaces (such as trend curves).
Data storage and transmission: The built-in storage function can save historical measurement data, and supports exporting data through interfaces such as Bluetooth, USB, RS485, etc. for easy analysis and recording.
Intelligent diagnostic function: Some models have functions such as probe installation status detection and signal quality evaluation, which prompt for operational errors or equipment abnormalities.
6. Low installation and maintenance costs
No need for professional tools: The external clamp probe is fixed by magnetic suction or fixtures, and the insertion installation process is simple, reducing labor and time costs.
Low maintenance requirements: Non contact design avoids probe wear or corrosion, has a long service life, and reduces regular maintenance frequency.
No consumables consumption: No need to replace vulnerable parts such as filters and seals, low long-term usage cost.
7. Safety and Environmental Protection
No potential leakage risk: The external clamp installation does not touch the inside of the pipeline at all, avoiding the leakage hazards caused by traditional instruments (such as orifice plates and turbines) due to installation openings.
Compliant with environmental requirements: Suitable for scenarios with high hygiene requirements such as drinking water, food and medicine, to avoid pollution risks.
8. Strong adaptability and high scalability
Suitable for complex working conditions: Some models support high temperature (such as -40 ºC~200 ºC) and high pressure environments, meeting the harsh conditions of industrial sites.
Multi scenario extension: can be paired with different types of probes (such as high-temperature probes, small diameter probes), or linked with software systems to achieve remote monitoring and data management.
