In real industrial environments, flow measurement often faces practical constraints:
Pipelines cannot be shut down or cut
Temporary measurements for commissioning, troubleshooting, or energy audits
Wide pipe diameter ranges across different locations
Requirement for fast deployment and immediate results
Portable ultrasonic flow meters are specifically designed for non-permanent, on-site measurement tasks where flexibility and speed are critical.
Flow Meter Description
Solving Field Uncertainty, Not Just Measuring Flow
Unlike fixed mechanical or differential pressure flow meters, portable ultrasonic flow meters are designed for maximum field adaptability rather than permanent installation.
Non-intrusive measurement – clamp-on installation without cutting, welding, or process interruption
Rapid deployment – sensors can be mounted and commissioned within minutes
One instrument, multiple pipelines – ideal for inspection, verification, troubleshooting, and comparative testing
Immediate data availability – supports real-time diagnostics, performance evaluation, and decision-making
For engineers, a portable ultrasonic flow meter serves as a mobile diagnostic and verification tool, enabling confident on-site measurement under changing field conditions.


Portable Ultrasonic Flowmeter Working Principle
Portable ultrasonic flow meters use the Transit-Time (Time-of-Flight) method:
Ultrasonic signals are transmitted with and against the flow direction
Flow velocity causes a difference in upstream and downstream travel time
The time difference is converted into average flow velocity
Volume flow rate is calculated based on pipe diameter parameters
✔ No contact with the medium
✔ Independent of pressure
✔ No moving or wearing parts
Portable Ultrasonic Flow Meter Mechanical Design & Reliability
Portability does not mean reduced robustness. The structural design focuses on on-site reliability:
Main unit: High-contrast backlit LCD for outdoor and low-light environments
Sensors: Clamp-on or insertion types for different pipe sizes and materials
Cabling & interfaces: Industrial-grade, resistant to bending and electromagnetic interference
Internal structure: No mechanical wear components, ensuring long-term stability
Ideal for repeated inspections, multi-point testing, and cross-project use.


Portable Ultrasonic Flowmeter Typical Applications
Industrial cooling water and circulation systems
HVAC system commissioning and energy evaluation
Temporary flow verification and comparative testing
Flow assessment prior to pipeline retrofitting
Energy audits and efficiency improvement projects

Yes, under stable flow conditions and with sufficient straight pipe length, low flow measurement is achievable.
Small, evenly distributed bubbles have limited impact, while excessive aeration or two-phase flow may reduce signal stability.
Yes. Clamp-on ultrasonic technology is particularly advantageous for large pipelines due to low installation cost and minimal disruption.
No. The same instrument can be used with different pipe materials by adjusting sensor parameters.
The device supports continuous operation, although it is primarily designed for portable and temporary measurement tasks.
Yes. When combined with temperature sensors, it can calculate thermal energy for heating and cooling applications.
