Choosing between two capable ultrasonic flowmeters for pressure flow process measurement can come down to one question: do you need to carry the meter to the pipe, or keep the meter on the pipe? The Portable TDS-100H and the Wall-Mounted TUF-2000B both use ultrasonic measurement and list ±1% accuracy, but they are designed for different working styles. Here is how to decide.
Quick verdict
If your work involves checking flow at several pipe locations, the Portable TDS-100H is the easier fit. If you need a permanent monitor at one point, the Wall-Mounted TUF-2000B is the more natural setup. The deciding factor is mobility versus fixed installation.
At a glance
| Product | Form | Pipe/range guidance | Output interface | Listed price |
|---|---|---|---|---|
| Portable TDS-100H (DN50-700) | Portable | DN50-700, ±32 m/s | RS-232C | USD 300.00 |
| Wall Mounted TUF-2000B | Wall/rail mount | TS-2: 0.78-3.94 in; TM-1: 1.97-27.56 in | RS485 (MODBUS) | USD 240.01 |
Where each product wins
The Portable TDS-100H wins when the meter has to move. It uses non-contact ultrasound, includes a 24k-byte data logger for up to 10,000 lines of data, and has a 4x16 English-letter display, which makes it practical for field surveys and multi-point rounds.
The Wall-Mounted TUF-2000B wins when the meter can stay in one place. The listed package includes the host unit, mounting hardware, and signal cable, so setup at a single point is straightforward. That makes it a strong fit for fixed monitoring.
Product notes
Portable TDS-100H Ultrasonic Flowmeter (DN50-700)
The Portable TDS-100H earns its place when you need readings from multiple pipes. Its non-contact ultrasonic measurement and the listed DN50-700 range give you a broad starting point for line checks. It has a metal-and-plastic build that is strong and durable, and it is described as stable and safe to use. The data logger stores up to 10,000 lines of data, which is useful for a day of field measurements. The RS-232C output lets you pull data to a connected device. The limitation is that it is a portable unit, so it is not meant to stay fixed to one pipe; if your process requires continuous monitoring at one point, a wall-mounted unit is the more practical route.
Wall Mounted Digital Ultrasonic Flowmeter Water Flow Meter & TM-1 TS-2 TUF-2000B
The Wall-Mounted TUF-2000B is built for a dedicated spot. It mounts on a wall or rail, and the package includes the TUF-2000B host, TS-2 and TM-1 ultrasonic transducers, two steel belts, a 32.81 ft signal cable, a connection terminal, and an English manual-everything needed to set up on a selected pipe. It communicates over RS485 with MODBUS support, so it can sit in a fixed control loop. The ABS and steel construction is aimed at stable, reliable service. The limitation: once it is mounted, it is not something you will carry from line to line. If your work is all at one location and you need a permanent installation, it is the fit; if you need to move between lines, the TDS-100H is better.
Final choice by use case
Choose the Portable TDS-100H if you run field checks, measure different pipe sizes, or need a portable tool for on-the-go readings. Choose the Wall-Mounted TUF-2000B if you want a fixed flow meter at one point. At their listed prices-USD 300.00 for the portable and USD 240.01 for the wall-mounted-the wall-mounted unit is the lower-priced option, while the portable earns its higher price through mobility.
