Choosing a flow meter for pressure flow process measurement often comes down to two different ways to read the same line. One option uses ultrasonic pulses to measure through the pipe; the other spins a turbine inside the flow. The Ultrasonic Flow Meter TUF-2000M and the Blancett B111-120 Model 1100 both deliver flow readings, but they ask different things from your piping. Here is how to pick between them.
Quick verdict
The $150 Ultrasonic Flow Meter TUF-2000M and the $320 Blancett B111-120 Model 1100 take different routes to flow measurement. The right one depends on whether you want the lower-cost ultrasonic package or the higher-cost inline turbine package. The $170 price gap reflects a difference in meter technology and intended installation, not a simple quality gap.
At a glance
| Feature | Ultrasonic TUF-2000M | Blancett B111-120 Model 1100 |
|---|---|---|
| Price | $150.00 | $320.00 |
| Meter type | Ultrasonic, non-contact | Turbine with magnetic pickup |
| Port diameter | - | 2-inch NPT female |
| Flow range | - | 40-400 GPM |
| Signal outputs | 4-20 mA | OCT pulse | relay | 3-way 4-20 mA input | Magnetic pickup B111109 |
Where each product wins
The TUF-2000M wins when you want a self-contained ultrasonic flow meter package and the flexibility to use the readings in different ways. It suits buyers who already have a pipe arrangement and want to avoid installing an inline meter.
The Blancett Model 1100 wins when you know your line size and expected flow and want a dedicated inline turbine meter. It suits oil and gas, produced water, and industrial process applications where a direct meter is the expected fit.
Product notes
Ultrasonic Flow Meter TUF-2000M with TS-2 Transducer
The TUF-2000M is the more flexible signal platform in this matchup. It outputs a 4-20 mA signal, an OCT pulse, and a relay output, and it also accepts a 4-20 mA input, so it can play a bigger role in a control loop. The ultrasonic sensing method measures without mechanical contact, which is a clean way to monitor existing piping. The main limitation to weigh is that the package is a meter-and-transducer kit rather than a drop-in inline meter, so you need to know how it will mount on your line. If you want non-contact measurement with multiple output options, this is the one.
Blancett B111-120 Model 1100 Turbine Flow Meter
The Blancett B111-120 Model 1100 is a purpose-built inline turbine meter with a 2-inch NPT female connection and a 40-400 GPM measuring range. The 316 stainless steel body is selected for demanding service, and the included B111109 magnetic pickup plus factory K-Factor calibration label give you a defined signal reference. That makes it a direct choice when your line size and flow rate are already known. The limitation is the sales context: this is a surplus unit sold as-is with no returns, so you are buying the hardware and the calibration data rather than a warranty-backed retail purchase. If you need a rugged 2-inch turbine meter and can accept that as-is condition, it covers the job well.
Final choice by use case
For pressure flow process measurement, choose the Ultrasonic Flow Meter TUF-2000M when you want a lower-cost ultrasonic package. Choose the Blancett B111-120 Model 1100 when you want a dedicated inline turbine meter.
