Choosing between two ultrasonic flow meters usually comes down to how much pipe flexibility and data you need. On one side, the Ultrasonic Flow Meter TUF-2000M with the TS-2 transducer is a no-frills workhorse at USD 150.00. On the other, the Portable Ultrasonic Liquid Flowmeter TDS-100H DN50-700 Flow Meter M2 US costs twice as much at USD 300.00, but it brings a built-in data logger and RS-232C connectivity. This head-to-head will help you decide which meter deserves the spot on your pipeline.
Quick Verdict
If your primary goal is a dependable fixed flow measurement without paying for extras you won't use, the TUF-2000M is the smart buy. If you need to move from pipe to pipe, capture long-running data logs, or connect to a computer, the TDS-100H is worth the extra money. The choice really comes down to whether you view a flow meter as a permanent fixture or a portable toolkit.
At-a-Glance Comparison
| TUF-2000M at USD 150.00 | TDS-100H at USD 300.00 |
|---|---|
| Fixed meter with included transducer | Portable flowmeter for DN50-700 pipes |
| 4-20mA output, OCT pulse, relay | ±32 m/s measurement range |
| 3-way 4-20mA inputs | ±1% accuracy |
| RS-232C, baud 75-115,200bps | |
| 24k-byte data logger (10,000 lines) | |
| 4x16 English-letter display |
Where Each Product Wins
The TUF-2000M wins when your installation is permanent and your budget is tight. It gives you direct signal outputs and inputs that play nicely with control systems and alarms. You get that signal flexibility without spending extra for a feature set you won't fully use.
The TDS-100H wins for fieldwork and jobs where you need a meter that can adapt to different piping setups. It's the more versatile choice for a technician who needs answers on site.
Product Notes
#### Ultrasonic Flow Meter TUF-2000M w/ Ultrasonic Transducer TS-2
The TUF-2000M is the more budget-friendly pick, especially if you already have a control system in place. It comes with the transducer, so you can start measuring without hunting for extras. It's the kind of meter you install once and then forget about-provided you're not expecting it to double as a portable instrument. If your setup is fixed, this is a straightforward way to get flow data into your process without a big expense.
#### Portable Ultrasonic Liquid Flowmeter Pipeline TDS-100H DN50-700 Flow Meter M2 US
The TDS-100H asks for a bigger budget, but it buys you a meter that goes where the work is. For a technician who moves between measuring points, the convenience of having all the essential tools in one case is a real time-saver. The price is the main hurdle, but if you'd otherwise need to assemble a separate portable setup, this all-in-one approach can be the more practical investment.
Final Choice by Use Case
For a fixed installation that needs dependable flow signals without breaking the bank, choose the Ultrasonic Flow Meter TUF-2000M. It's the more affordable option, and it still gives you multiple output and input paths.
For fieldwork, multi-pipe monitoring, or any job that requires collecting and moving measurement history, the Portable Ultrasonic Liquid Flowmeter TDS-100H is worth the higher spend. It earns its place in a technician's kit when the pipes aren't all in one room.
