Choosing a flow meter for pressure flow process measurement means choosing between very different jobs. At one end, a $16.95 hose-end meter can tell you when the RV tank is full. At the other, a $499.99 industrial meter is aimed at process work. In between are a high-volume flow meter and a fixed meter with separate transducers, so the first question should be about your pipe and flow range.
Quick take
The DWYER UXF2 has the highest price in the group. The Blancett B111-120 is listed as new/open-box and is built for high-volume flow work. The TUF-2000B uses separate transducers. The Water Flow Meter for Garden Hose is a compact meter for watering and RV tank filling.

Product notes
DWYER UXF2 Flow Meter
The UXF2 is a general-purpose industrial flow meter from Dwyer, made for measuring liquids or gases in pumping systems and related fluid-management work. That makes it a fit for a process line where you need one instrument for different media. The catch is its status: it is the only product in this group listed as used, and it sits at the top of the price scale. If you already have experience with Dwyer instruments and are comfortable buying used equipment, this may be the candidate to evaluate. If you want a new unit, this used meter is not it.
Blancett B111-120 Model 1100 Turbine Flow Meter 2\" NPT 40-400 GPM 316SS NEW
If you need to handle high-volume liquid flows, the Blancett B111-120 is aimed squarely at that job. It is a Model 1100 turbine meter with a 2-inch NPT female connection and a 40-400 GPM range. The 316L stainless steel body handles corrosive and abrasive service, and it includes the factory K-factor calibration label. It is described as new, unused, and in the original box, with a condition of new/open-box. The trade-off is that it is sold as-is with no returns, so compatibility and calibration are your responsibility after purchase.
Water Flow Meter for Garden Hose for Watering or Filling RV Tank - Monitor Usage
For a quick, low-cost way to monitor outside water use, the Water Flow Meter for Garden Hose from Conserve It! is a direct fit. It connects to a 3/4-inch hose faucet and displays readings in gallons or liters, with both single-use and cumulative modes. That means you can measure one RV tank fill or keep a running total over a season. It has a pre-installed battery and a spare washer in the package. The limits are clear: it is not made for very hot water, it is recommended for outdoor use only, and it requires at least 7.3 psi to operate.
Ultrasonic Flow Meter TUF-2000B +TM-1 + TS-2 DN20~700m Fixed Clamp on Flowmeter
The TUF-2000B package combines a fixed ultrasonic transmitter, a TM-1 transducer, and a TS-2 clamp set. The accuracy is ±1%, and the meter can measure flow in both directions. It also supports RS485 with MODBUS, which is useful for sending readings to a controller. The trade-off is that the SD card for interval data recording is not included, so you will need to supply your own if you want that feature. This is a clamp-on design, so the sensors mount on the outside of the pipe rather than in the flow stream.
Final recommendation by use case
Use these picks as a starting point for your flow measurement setup.
- For measuring garden hose output or filling an RV tank, the Water Flow Meter for Garden Hose is the practical pick at the lowest listed price.
- For larger process flows, the Blancett B111-120 is the one to choose.
- For a meter that reports to a controller, the TUF-2000B measures in both directions.
- For a general-purpose industrial meter where you are comfortable with used equipment, the DWYER UXF2 is the model to inspect.
