Choosing a flow meter for pressure flow process measurement is really a pipe-and-purpose decision. Are you filling an RV tank from a garden hose, or are you monitoring a stainless process line that moves a higher flow? The four meters here span a listed price spread from $16.95 to $320, but the bigger number does not automatically mean a better fit. The hose-end turbine meter is the only unit that belongs on a spigot, while the two ultrasonic meters and the larger turbine are aimed at very different pipe sizes and mounting situations.
Quick take
- For a hose-end readout that tracks watering and RV tank fills: Conserve It! Garden Hose Water Meter.
- For a wall/rail-mounted display with external transducers: Wall Mounted Digital Ultrasonic Flowmeter TUF-2000B.
- For the other TUF-2000B ultrasonic option: Fixed Clamp-On Ultrasonic Flow Meter TUF-2000B.
- For industrial turbine service: Blancett B111-120 Turbine Flow Meter.
Listed price comparison
The table below shows the listed price spread. The two TUF-2000B ultrasonic meters sit between the $16.95 hose-end meter and the $320 industrial turbine meter, with the fixed clamp-on version priced lower than the wall-mounted version. The absolute spread from the low to the high listed price is about $303.

Product notes
Conserve It! Garden Hose Water Meter
This turbine meter connects at a 3/4-inch port and shows readings in gallons or liters. It calculates both single-use and cumulative water use, so you can compare one watering session against the season total, and the display runs on a pre-installed button battery. A spare black washer is included, and the green-and-black body is easy to spot on a spigot. The practical limit is the working envelope: it is recommended for outdoor use only, not with very high-temperature water, and it needs a minimum operating pressure of 7.3 psi to do its job.
Wall Mounted Digital Ultrasonic Flowmeter TUF-2000B
This unit is the one to look at when you want a display mounted on a wall or rail. The package includes the TUF-2000B host, TS-2 and TM-1 ultrasonic transducers, two steel belts, a 32.81-foot flow signal cable, and connection terminals, so the assembly has almost everything needed for a fixed setup. It is aimed at water supply, heating, and water conservation monitoring, and the LCD can show current and accumulated flow/heat when the right sensor is connected. The trade-off is that it is an assembly project: the components need to be fitted together, and the included transducers are the ones you must work with, covering 0.78 to 27.56 inches.
Fixed Clamp-On Ultrasonic Flow Meter TUF-2000B
This meter pairs the same TUF-2000B host with TM-1 and TS-2 transducers in a fixed clamp-on configuration. It measures bidirectionally and is not affected by system pressure or harsh environments, which makes it useful for pipeline liquid measurement with water, seawater, sewage, oil, or alcohol. The main limitation is recording: the SD card is not included, so interval recording requires a card you supply. If your existing setup already uses MODBUS, this unit is the more direct clamp-on match.
Blancett B111-120 Turbine Flow Meter
This meter is built for a different job than the hose-end units. It has a 2-inch NPT female connection and a 316L stainless steel body, with a measuring range of 40 to 400 GPM. The included factory K-Factor calibration label gives the unit a specific calibration value, and the magnetic pickup is specified as a B111109. Its intended roles include oil and gas, produced/injection water, water flood, and industrial process service. The limitation is equally clear: the 2-inch connection and higher flow range make it a poor match for small hoses, and it is sold as surplus, so treat it as an as-is industrial component.
Final recommendation by use case
- For outdoor hose watering and RV tank fills, the Conserve It! Garden Hose Water Meter is the only hose-end meter in the group. Its 3/4-inch port and single-use/cumulative totals make it the straightforward pick.
- For a permanent display with external transducers, the Wall Mounted Digital Ultrasonic Flowmeter TUF-2000B is the one to look at.
- For a fixed clamp-on ultrasonic meter, the Fixed Clamp-On Ultrasonic Flow Meter TUF-2000B is the lower-priced of the two TUF-2000B setups.
- For industrial process service with higher flow rates, the Blancett B111-120 Turbine Flow Meter is the match for a 40-400 GPM range and stainless construction.
