Built for Practical Industrial Flow Measurement
Lower Installation Complexity
Adding an inline flow meter can require pipe cutting, flanges, welding and shutdown planning. A properly selected ultrasonic clamp-on flow meter provides an alternative when buyers want to reduce mechanical installation work on an existing pipeline.
Support Permanent or Temporary Measurement
Depending on the selected model, clamp-on ultrasonic technology can support permanent monitoring, temporary flow verification, commissioning and troubleshooting.
Wide Application Flexibility
Different transducer configurations can support a broad range of pipe sizes, materials and temperatures. Final suitability should always be confirmed according to the actual pipe and liquid conditions.
Industrial System Integration
FlowT can review the required analog, pulse, relay or digital communication interface according to the selected model so engineers can plan connection to PLC, BMS, SCADA or data-acquisition systems.
No Moving Measuring Parts in the Flow Path
External ultrasonic measurement avoids adding mechanical moving elements inside the process stream, reducing concerns about wear and obstruction associated with some traditional meter technologies.
Application-Based Product Selection
FlowT reviews more than nominal pipe diameter. Pipe wall thickness, material, liner, liquid, temperature, flow conditions and installation location should all be considered before final model selection.

Why Choose Clamp-On Ultrasonic Flow Measurement?
Measure Without Pipe Modification
The ultrasonic transducers are installed on the external pipe surface, allowing flow measurement without automatically cutting or opening the process pipeline.
01
Minimize Process Interruption
For existing systems, clamp-on measurement can help reduce the need for shutdown, draining, welding and recommissioning work associated with installing an inline meter.
02
No Additional Pressure Drop
Because the measuring sensors remain outside the pipe, no measuring element is inserted into the flow path.
03
Easier Access for Inspection
External transducers remain accessible from outside the pipe, which can simplify inspection, repositioning and servicing.
04
Suitable for Retrofit Projects
Clamp-on technology is particularly useful when flow measurement needs to be added to an existing water, HVAC or industrial pipeline.

FAQ
Q: What is an ultrasonic clamp-on flow meter?
A: An ultrasonic clamp-on flow meter measures liquid flow using ultrasonic transducers mounted on the outside of a pipe. The sensors transmit ultrasonic signals through the pipe wall and liquid, allowing flow measurement without placing a measuring element directly into the process stream.
Q: Does a clamp-on ultrasonic flow meter require pipe cutting?
A: No pipe cutting is normally required for an external clamp-on installation. The sensors are mounted on the pipe surface, which is why the technology is commonly selected for retrofit and existing-pipeline applications.
Q: Can the meter be installed while the system is operating?
A: In many suitable applications, clamp-on sensors can be installed without opening the pipe or draining the process. Final installation procedures should still follow site safety and FlowT installation requirements.
Q: What liquids can be measured?
A: Transit-time clamp-on ultrasonic meters are generally best suited to liquids that provide stable ultrasonic transmission. Clean water, chilled water, hot water and many industrial liquids are common applications. Liquids with significant solids or gas bubbles require additional review.
Q: What pipe sizes can be measured?
A: The supported pipe range depends on the selected FlowT meter and transducer configuration. Send your pipe outside diameter and application conditions so the correct sensor range can be confirmed.
Q: What pipe materials are suitable?
A: Many metallic and plastic pipe materials can be evaluated for ultrasonic clamp-on measurement. Pipe wall thickness, lining, corrosion and acoustic properties must also be considered.
Q: How accurate is a clamp-on ultrasonic flow meter?
A: Accuracy depends not only on the instrument but also on pipe dimensions, liquid condition, sensor installation, straight-run availability and flow profile. The final accuracy specification should be confirmed for the selected FlowT model and application.
Q: Can the meter measure bidirectional flow?
A: Bidirectional measurement is supported by many ultrasonic flow meter configurations, but the exact capability should be confirmed for the selected model.
Q: Can the flow meter connect to a PLC or BMS?
A: Industrial communication options can be reviewed according to the selected FlowT model. Common project requirements include analog output, pulse, relay and RS485/Modbus communication.
Q: Can FlowT help select the correct model?
A: Yes. Send FlowT the pipe diameter, material, wall thickness, liquid, temperature, expected flow range and measurement purpose. The team can use this information to review the appropriate configuration.
