Sensors mount outside an existing pipe. This can avoid cutting the line and keeps the sensors out of contact with the water. [Honeywell clamp-on overview](https://process.honeywell.com/us/en/products/field-instruments/flow-meters/versaflow-clamp-on-ultrasonic-flow-meters)
MEASURING PRINCIPLE / ULTRASONICFIG. 03
Principle schematic · not a product drawing or installation detail
Advantages: attractive for surveys, troubleshooting and retrofits where shutdowns or wetted components are undesirable.
Limitations: performance depends on the installation, including actual pipe dimensions, lining, acoustic transmission and sensor coupling. A convenient temporary reading is not automatically an accepted billing measurement.
Before buying: supply outside diameter, wall thickness, material, lining, temperature, fluid properties and available straight pipe. Ask the supplier to assess the site and demonstrate signal quality. These are explicit inputs in the Siemens ultrasonic application data sheet.
What to specify for this type
Actual OD, wall thickness and lining
Fluid and pipe acoustic suitability
Coupling, mounting access and full pipe
Signal-quality demonstration and intended acceptance
Flow range and communications
Match actual minimum, normal, continuous maximum and peak flow to the exact configuration. A shared pipe size does not establish equivalent performance.
A connected metering system is five parts: meter → interface or module → network or gateway → software → billing, dashboard or control system. A quotation should name who supplies and maintains each one. AMR-ready equipment may still require separately quoted radio, gateway, head-end and billing software.
Does this type determine the final model and size?
No. Validate the fluid, flow range, pressure, temperature, orientation and acceptance requirements against the exact offered configuration.
Which accessories are included?
Only the written quotation can establish the supplied scope. Ask for the option code, pickup/module, power supply, gateway and required installation accessories.
