The decision: fuel-focused turbine or water-focused displacement meter
When you're choosing a meter for pressure flow process measurement, the first question is not price. It's how the meter measures the liquid and whether that matches the liquid you're pumping. These two options sit at opposite corners of that decision. The Brearo 1" Digital Turbine Flow Meter is a turbine unit aimed at diesel, kerosene, and fuel-pump work. The Badger 108-6670 Positive Displacement Flow Meter is a positive displacement flow disc meter listed for water. One is a lightweight inline meter for fuel transfer; the other is a displacement-style meter for water lines.
Quick verdict
If you're moving diesel or kerosene and want a digital readout with multiple unit options, the Brearo turbine flow meter is the straightforward low-cost pick. If you're metering water through a 3/4-inch NPT line and want a positive displacement meter, the Badger 108-6670 is the more appropriate tool. The price gap between them-$452-reflects different meter types and different application targets.

Where the Brearo wins
The Brearo is the clear pick when the job is a diesel or kerosene fuel pump and keeping meter cost low matters. Its digital display shows instantaneous and cumulative flow, and it supports gallons, quarts, pints, liters, and cubic meters, which is handy if you switch between units. The compact modular design keeps installation simple. It is not trying to be a water-process instrument; it is aimed at fuel-transfer duties.
Where the Badger wins
The Badger wins when you need a positive displacement meter for water. The flow disc design and 3/4-inch NPT connection fit a water line that expects displacement-style measurement. The listed media temperature window is 32°F to 80°F, so it suits temperate water service. It is a new unit made in Mexico. It is not the choice for a low-cost fuel-pump project; it is the choice for a water line where positive displacement is the requirement.
Product notes
Brearo 1" Digital Turbine Flow Meter
The Brearo digital turbine flow meter gives you a high-definition display with both instantaneous and cumulative flow, and the switchable units include gallons, quarts, pints, liters, and cubic meters. Its compact structure and modular design make it straightforward to install and maintain. It is a new unit and is the lower-priced entry in this head-to-head. If your application is moving diesel or kerosene through a fuel pump, this meter matches the task. The limitation is the application focus: it is not listed for water like the Badger, so if your line is water and you want a positive displacement flow disc meter, you should look at the Badger instead.
Badger 108-6670 Positive Displacement Flow Meter
The Badger 108-6670 is a positive displacement flow meter with a flow disc product type, listed for water. Its media temperature range is 32°F to 80°F. This is the meter to choose when you need positive displacement measurement in a water line-not a turbine-based flow reading. The limitation is the larger price tag compared with the Brearo, and its temperature range is not oriented toward hot or fuel-transfer service. If your process is water in a temperate range and positive displacement is the expected meter technology, this model is the one that lines up.
Final choice by use case
- For diesel or kerosene fuel transfer: choose the Brearo 1" Digital Turbine Flow Meter. The fuel-focused design and digital unit flexibility align with the job.
- For a water line with a 3/4-inch NPT connection: choose the Badger 108-6670 Positive Displacement Flow Meter. The positive displacement flow disc design and water listing make it the right match.
- If keeping the meter cost low matters for a fuel application, the Brearo is the clear fit. If meter technology matters more and the liquid is water, the Badger is the clear fit.
