When you need a flow meter for pressure flow process measurement, the first fork in the road is the measuring principle: do you want an ultrasonic meter that reads fluid velocity through sound waves, or a positive displacement meter that physically counts the liquid? Here we compare two specific options: the Ultrasonic Flow Meter TUF-2000M with TS-2 transducer at $150, and the Badger 108-6670 Positive Displacement Flow Meter at $477.99.
Quick Verdict
The Ultrasonic TUF-2000M is the lower-priced, more versatile choice, especially if you need multiple signal outputs and prefer no mechanical contact with the fluid. The Badger 108-6670 is a defined positive displacement meter for water, with a 3/4-inch NPT connection and a narrow temperature range. Your decision comes down to whether you want a flexible ultrasonic system or a straightforward mechanical water meter.
Comparison Table
| Product | Price | Measuring Principle |
|---|---|---|
| Ultrasonic Flow Meter TUF-2000M w/ TS-2 | USD 150.00 | Ultrasonic |
| Badger 108-6670 Positive Displacement Flow Meter | USD 477.99 | Positive Displacement |
Where Each Product Wins
Ultrasonic TUF-2000M wins if:
- You need non-contact flow measurement without moving parts in the stream.
- You want multiple output signals (4-20mA, OCT pulse, relay, and three 4-20mA inputs) for control or logging.
- You're looking for a lower price point while still getting a complete meter-plus-transducer system.
Badger 108-6670 wins if:
- You specifically need a positive displacement meter for water.
- A 3/4-inch NPT connection is a good fit for your piping.
- Your media stays within 32-80°F, making this a well-defined option for cold-water service.
Product Notes
Ultrasonic Flow Meter TUF-2000M w/ Ultrasonic Transducer TS-2
The TUF-2000M measures flow with ultrasonic waves and includes the TS-2 transducer, so the kit has two main pieces. It lists signal outputs of 4-20mA, OCT pulse, relay, and three 4-20mA inputs, giving you multiple ways to send data to a controller. At USD 150.00, it's the more affordable of the two meters. If you need to monitor flow without putting a mechanical element into the pipe, this is a solid option. The trade-off is that the meter and transducer need to be set up together, which may require more alignment work than a single integrated meter.
Badger 108-6670 Positive Displacement Flow Meter
The Badger 108-6670 is a positive displacement meter designed for water. It has a 3/4-inch NPT connection and a media temperature range of 32 to 80 degrees Fahrenheit. At USD 477.99, it costs more than the Ultrasonic option. The description confirms it's for water, so if you need a mechanical, positive displacement approach for a cold-water line, this gives you a defined solution. The trade-off is that the temperature range is narrow, so it's not suitable for hot water or other fluids. It also lists "Battery Included: No," meaning power is not part of the package.
Final Choice by Use Case
For pressure flow process measurement where you want ultrasonic technology, multiple signal outputs, and a lower price, the Ultrasonic Flow Meter TUF-2000M w/ TS-2 is the natural pick. For a water line that needs a positive displacement meter with a specified NPT connection and a moderate temperature envelope, the Badger 108-6670 is the clearer choice. Match the meter to the fluid behavior and your control system, not just the upfront cost.
