Designed for Small Diameter Pipeline Flow Monitoring
In many industrial and commercial systems, flow measurement on small diameter pipelines presents unique challenges:
Limited installation space
No allowance for pipe cutting or process shutdown
Requirement for quick installation and minimal maintenance
Corrosive or humid operating environments
The integrated clamp-on ultrasonic flowmeter is specifically developed to address these scenarios, providing reliable flow monitoring for DN10–DN40 pipelines without disturbing the process.
Flow Meter Description
Ultrasonic Flowmeter Clamp On-Simple Installation, Stable Measurement, Zero Process Interruption
Unlike traditional inline flowmeters, this clamp-on ultrasonic flowmeter focuses on ease of deployment and operational safety:
Non-intrusive measurement – no pipe cutting, no welding, no production stoppage
Integrated compact design – small footprint, ideal for confined installations
No moving parts – no pressure loss and minimal maintenance
No electrical conductivity required – suitable for water and other non-conductive liquids
Installation can be completed by on-site personnel without specialized training, following installation videos or step-by-step diagrams.
Ultrasonic Water Flow Meter-Working Principle
The ultrasonic flowmeter clamp-on operates using the transit-time principle:
Ultrasonic signals are transmitted through the pipe wall and liquid
Signals travel with and against the flow direction
The difference in propagation time is proportional to the flow velocity
The instrument calculates volumetric flow based on pipe size and velocity
Since the sensors are mounted externally, the measurement is completely isolated from the process medium.
Ultrasonic Flow Meter-Typical Applications
Small diameter water distribution pipelines
Equipment cooling lines
Chemical dosing and auxiliary process lines
OEM equipment flow monitoring
Skid-mounted systems and compact process units
