Why Choose Clamp-On Ultrasonic Flow Measurement?
No Pipe Cutting
The ultrasonic transducers are mounted externally on the pipe surface.For suitable applications, this allows flow measurement to be added without cutting the pipe, welding flanges or installing a conventional inline sensor body.This can simplify retrofit projects and reduce the mechanical work required to add a new measurement point.
No Additional Pressure Drop
Because no meter body is inserted into the flow path, clamp-on ultrasonic measurement does not create the same type of obstruction associated with some inline flow technologies.This can be particularly valuable in water, utility and process systems where maintaining available pressure is important.
No Direct Contact With the Liquid
This helps reduce direct sensor exposure to the measured liquid and can be useful in applications where process contact, contamination risk or corrosion of wetted components is a concern.
Fixed or Portable Measurement
Depending on project requirements, ultrasonic flow measurement can be configured for permanent monitoring or temporary field measurement.Fixed systems are suitable for continuous monitoring, while portable configurations can support commissioning, verification, troubleshooting and temporary flow surveys.
Low Mechanical Maintenance
Clamp-on measurement does not rely on moving components inside the liquid stream.This can reduce process-side maintenance and make the technology attractive for long-term water and industrial liquid monitoring.
Broad Industrial Application
The technology can be applied across water and wastewater, agriculture, chemical and petrochemical, food and beverage, mining, oil and gas, power and energy, pulp and paper and other compatible liquid-flow applications.
Key Features for Industrial Flow Measurement
Non-Invasive Clamp-On Sensors
The transducers are mounted on the outside of the pipe, allowing flow measurement without inserting a conventional sensor directly into the process stream.This makes the technology attractive for retrofit projects and existing pipelines where mechanical modification would be costly or disruptive.
01
Fixed and Portable Configurations
FlowT ultrasonic flow measurement solutions can be selected for permanent or temporary use depending on the project.Fixed systems support continuous monitoring, while portable configurations are useful for field surveys, commissioning, diagnostics and flow verification.
02
No Additional Meter-Body Pressure Loss
The measuring sensors do not create an internal obstruction in the flow path.For water distribution, utility systems and process pipelines, this helps preserve the existing hydraulic condition of the pipeline.
03
Measurement of Water and Compatible Liquids
The system can be evaluated for pure water, wash water, sea water, suitable wastewater, process liquids, oils and compatible chemicals.Final suitability depends on the acoustic properties of the liquid and the pipe conditions.
04
Bidirectional Flow Measurement
Ultrasonic measurement can support forward and reverse flow monitoring when the selected model and configuration allow it.This is useful for pipelines where reverse flow may occur during process changes, balancing or system operation.
05
Although this product is positioned around water measurement, clamp-on transit-time ultrasonic technology can also be used with other compatible liquids that provide suitable ultrasonic transmission.
Typical applications may include:
Pure Water
Suitable for utility water, process water and clean-water monitoring.
Wash Water
Applicable to cleaning and washing systems where the liquid remains acoustically suitable.
Sea Water
Can be evaluated for marine, desalination and coastal utility applications where pipe and liquid conditions are appropriate.
Suitable Wastewater
Transit-time ultrasonic measurement can be applied to some wastewater conditions, but excessive air bubbles or suspended solids may reduce signal quality.
Process Liquids
Suitable homogeneous process liquids can be evaluated according to their acoustic properties, temperature and pipe conditions.
Oils
Certain oils can be measured when their acoustic characteristics and operating conditions are compatible with transit-time ultrasonic measurement.

FAQ
Q: What is a water measurement ultrasonic flow meter?
A: A water measurement ultrasonic flow meter uses ultrasonic signals to calculate liquid velocity and volumetric flow.With a clamp-on configuration, the transducers are mounted outside the pipe, allowing flow measurement without inserting a conventional sensor into the liquid stream.
Q: Is this product only suitable for water?
A: No.Although water measurement is a major application, transit-time ultrasonic flow meters can also be used with compatible homogeneous liquids such as wash water, sea water, selected process liquids, oils and compatible chemicals.Final suitability depends on the acoustic properties of the liquid and the pipe conditions.
Q: Can the meter be installed without cutting the pipe?
A: Yes, for clamp-on configurations.The sensors are mounted externally, so the pipe normally does not need to be cut to install the ultrasonic transducers.
Q: Does clamp-on measurement create pressure loss?
A: The clamp-on sensors remain outside the pipe and do not create an internal meter-body obstruction. This means the measurement system itself does not add the same type of pressure restriction associated with some inline meter designs.
Q: Can it measure wastewater?
A: Some wastewater applications may be suitable, but performance depends on the amount of suspended solids, entrained air and other acoustic conditions. Please provide information about the wastewater before selecting the meter.
Q: Can it measure oil or chemicals?
A: Selected oils and compatible chemicals can be evaluated for transit-time ultrasonic measurement. The final selection depends on liquid acoustic properties, temperature and pipe material.
Q: What information is required for model selection?
A: Please provide pipe diameter, pipe material, wall thickness, liquid type, operating temperature, expected flow range, installation environment, required output, communication requirement and whether the meter will be permanently installed or used as a portable instrument.
Q: Should I choose a fixed or portable ultrasonic flow meter?
A: Choose a fixed meter when continuous monitoring and permanent system integration are required. Choose a portable meter for commissioning, field survey, temporary monitoring, troubleshooting or flow verification across multiple pipelines.
Q: What affects ultrasonic flow meter accuracy?
A: Measurement can be affected by pipe dimensions, pipe material, liquid properties, sensor spacing, installation location, straight pipe length, flow profile, entrained air and suspended solids. Accurate application data and correct installation are important for reliable performance.
Q: Can it connect to PLC or SCADA?
A: Communication options depend on the selected transmitter model.
If PLC, SCADA, BMS or remote monitoring integration is required, provide the required analog or digital protocol during quotation.
Q: Can FlowT provide calibration or test reports?
A: Factory test and calibration documentation can be discussed according to the selected model and project requirements.
Please specify documentation requirements before ordering.
Q: Do you support OEM/ODM?
A: Yes. FlowT supports OEM/ODM discussion for qualified distribution, system integration and project orders. Branding, packaging, documentation and configuration requirements should be confirmed before quotation.
Q: Can I request a sample?
A: Sample availability depends on the selected model and project requirements.Providing your application information together with the sample request helps FlowT recommend a suitable evaluation configuration.
Q: What is the MOQ?
A: MOQ depends on the selected model and customization requirements.Standard configurations and OEM/private-label orders may have different commercial conditions.
Q: What is the lead time?
A: Lead time depends on model availability, order quantity, configuration, testing and customization requirements. Provide your target delivery schedule when requesting a quotation.
