Doppler instruments use reflections from suitable suspended particles or bubbles. They may be useful in applications where those reflectors are present consistently.
MEASURING PRINCIPLE / ULTRASONICFIG. 03
Principle schematic · not a product drawing or installation detail
They are not a universal choice for clean drinking water, and “ultrasonic” on a quotation is insufficient. Ask whether the offered instrument is transit-time or Doppler and what fluid conditions it needs. Kamstrup explanation of ultrasonic principles
What to specify for this type
Reflector size, quantity and consistency
Fluid changes during the operating cycle
Installation style and full/partial-pipe qualification
Application-specific validation
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.
No exact model is established for this category in the current documented range. Send the application so the appropriate system can be assessed.
Questions before you choose
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.
Ready to discuss your requirement?
Send a model code, BOQ or a brief description of your application. Add technical details if you have them.
