A compound meter combines a low-flow measuring path with a high-flow path. A switching arrangement allows it to cover large variations in demand. This makes the category relevant to facilities with low overnight use and large peaks. [Badger Meter compound meters](https://www.badgermeter.com/products/meters/compound/)

Advantages: a way to address a wide demand range when one conventional mechanical element would be a compromise.
Limitations: more components, crossover behavior and maintenance requirements. Both measuring paths and the changeover need attention.
Before buying: ask for the complete accuracy curve through crossover, total pressure loss, service procedure and how both registers are combined remotely.
What to specify for this type
Full flow profile including overnight demand
Changeover/crossover accuracy
Combined register integration
Maintenance and pressure-loss curve
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.

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.
