In pressure flow process measurement, choosing a flow meter isn't just about picking a brand. The internal technology decides what you can accurately measure. Turbine meters use a spinning rotor; positive displacement meters trap fixed volumes of liquid. The Blancett B111-120 Model 1100 is a turbine meter built for industrial liquid lines. The Badger 108-6670 is a positive displacement meter designed for water service. They sit at different ends of the process flow spectrum, and this head-to-head looks at which one belongs in your setup.
Before you look at specifications, consider what the two designs imply. The Blancett points to larger-volume flows and tougher industrial service. The Badger points to smaller, cleaner water lines with a modest temperature ceiling. That difference drives the decision more than brand preference. Getting this distinction right up front saves you from buying a meter that can't handle your service.
Quick verdict: For higher-flow industrial service, the Blancett turbine meter is the lower-priced choice at $320. For smaller water lines with moderate temperatures, the Badger positive displacement meter at $477.99 gives you a fixed-volume approach and a defined accuracy spec.
| Product | Listed Price | Meter Type | Connection | Key Specs |
|---|---|---|---|---|
| Blancett B111-120 Model 1100 | $320.00 | Turbine flow meter | 2" NPT | 40-400 GPM, 316L stainless steel body |
| Badger 108-6670 | $477.99 | Positive displacement flowmeter | 3/4" NPT | Water, 32-80°F, 5% accuracy |
Where each product wins
The Blancett wins on flow capacity and construction. Its 316L stainless steel body and broad flow range make it a fit for corrosive or abrasive process lines. It ships with a factory K-factor calibration label, so you have the calibration reference right on the unit. The main caveat is the sale terms: it's surplus inventory, sold as-is with no returns.
The Badger wins on predictable water metering. The positive displacement design is about fixed-volume measurement, which can make small-line water readings easier to reason about. It's listed as new, avoiding the open-box caveat. The trade-off is its narrower application window, limited to water at moderate temperatures.
Blancett B111-120 Model 1100 Turbine Flow Meter
With a 2-inch NPT connection and a 40-400 GPM range, the Blancett turbine meter is sized for substantial process lines. The 316L stainless steel body is meant for corrosive and abrasive service, and the factory K-factor calibration label provides the calibration reference. This unit has a listed K-Factor of 48.612. It's new, but the box has been opened. The limitation is the sale terms: sold as-is with no returns, so confirm your pipe size and flow range before ordering. It's a strong option for industrial liquid flow in demanding service.
Badger 108-6670 Positive Displacement Flow Meter
The Badger positive displacement meter uses a 3/4-inch NPT connection and is designed for water service between 32°F and 80°F. As a positive displacement meter, it measures in discrete volumes rather than by rotor speed. The 5% accuracy spec gives a concrete expectation for flow readings. For a small line carrying low-temperature water, the fixed-volume design offers a straightforward way to meter flow. Its limitation is water-only compatibility, with a temperature ceiling of 80°F. If your process runs hotter or uses a different liquid, this meter isn't suited. Within that water-service range, it's a dependable pick.
Final choice by use case
Pick the Blancett when you need a turbine meter for higher-flow industrial service and you can accept an as-is, no-returns sale. Pick the Badger when you need a fixed-volume water meter for a smaller line with moderate temperatures and you want a defined accuracy spec.
