Ultrasonic Flow Meter Tuf-2000b Tm-1 & Ts-2, Liquid Flowmeter
Best for: Industrial-scale liquid flow monitoring where multiple liquids and outputs are needed. The Tuf-2000B system includes TM-1 and TS-2 transducers, with 4-20mA, pulse, and relay outputs, plus 3-20mA inputs for control integration. This makes it a strong choice for facilities requiring robust data communication and flexible installation.
Why selected: It supports a wide range of liquids and has a complete accessory set for installation and maintenance. The 10-meter signal cable and silicone sealants simplify field work.
Limitation: Complex setup may require technical knowledge for optimal calibration and integration with existing control systems.
Bonvoisin Handheld Ultrasonic Flow Meter
Best for: On-site measurements where pipe cutting or downtime must be avoided. The device is clamp-on and portable, with S1+M2 sensors for quick setup and a data logger capable of storing up to 2000 data points.
Why selected: It offers convenient data download and real-time display without interrupting the process. It’s suitable for seawater, alcohol, and sewage applications when paired with the right sensors.
Limitation: Larger lines or custom sensors may require additional equipment; check sensor availability for DN300-6000mm if needed.
Ultrasonic Flow Meter with Small & Medium Transducers
Best for: General purpose flow measurement in a variety of liquids, including water and seawater, across a range of pipe materials. The transducers support 20 to 700 mm diameters with high temperature tolerance (-40°C to 160°C).
Why selected: High compatibility with common pipe materials and liquids, making it a versatile option for many facilities that need reliable, wide-ranging measurements.
Limitation: Ensure your pipe material and liquid are within the supported range; read the datasheet for exact Liq compatibility.
GOYOJO Ultrasonic Flow Meter with Clamp-on Transducers
Best for: Water-flow control in residential and commercial settings needing a durable, IP68-protected meter. The device supports a wide temperature range and emphasizes practical use in irrigation and building management.
Why selected: It provides clear LCD display, robust protection, and straightforward operation, making it an effective all-around measurement option for non-industrial sites.
Limitation: May be less suited for extreme industrial media or very harsh chemical environments without verifying material compatibility.
TUF-2000B Ultrasonic Flow Meter by DONSU
Best for: Outdoor installation and long-term monitoring where durability and bi-directional measurement are critical. The meter is designed for outdoor use with IP67/IP68 protection and a robust housing.
Why selected: It supports bi-directional measurement and a comprehensive outdoor-ready build, suitable for water supply, heating, and other utilities.
Limitation: Outdoor deployment requires planning for weather exposure and maintenance of protective shells over time.
Buying Guide
What to consider when choosing an ultrasonic water meter:
- Liquid compatibility: Confirm whether the meter supports water, seawater, wastewater, oil, or alcohol as needed.
- Pipe size range: Check if DN20-700 mm or other diameters are supported by the transducers.
- Transducer type: Clamp-on versus in-line/transducer configurations affect installation complexity and pipe integrity.
- Protection and durability: IP ratings (IP67/IP68) indicate suitability for outdoor and harsh environments.
- Outputs and integration: 4-20mA, pulse, and relay outputs, plus RS485 or other communication protocols for SCADA/AMR integration.
- Temperature and pressure ratings: Ensure operation within the liquid temperature range and system pressure.
- Data handling: Look for data logging, storage capacity, and software access if long-term monitoring is required.
Practical comparison tips
- For industrial operators requiring robust integration, prioritize meters with multiple outputs and RS485 or other digital communication.
- For field engineers and maintenance crews, a handheld or clamp-on design with a clear display and data logging may reduce downtime.
- For outdoor installations, prioritize IP67/IP68 protection and durable housings to resist dust, moisture, and corrosion.
- For versatile liquid handling, choose meters that claim compatibility with a wide range of liquids and pipe materials.
FAQ
- What is an ultrasonic water meter? An ultrasonic water meter uses sound waves to measure flow by detecting the time it takes for a signal to travel between transducers through the liquid.
- What is the difference between clamp-on and inline meters? Clamp-on meters attach to the outside of the pipe, causing no disruption to flow, while inline meters are installed inside or as part of the piping, often requiring pipe access.
- Can ultrasonic meters measure hot liquids? Some models have high-temperature transducers and can measure liquids at elevated temperatures; check the temperature range for each model.
- Are ultrasonic meters suitable for all pipe materials? Many models support common materials like copper, PVC, steel, and cast iron, but verify compatibility with your specific pipe and liquid.
- Do these meters require calibration? Some meters include factory calibration and optional field calibration; verify with the supplier if precise calibration is needed for billing or regulatory purposes.
- What installation considerations matter? Consider pipe diameter, transducer placement, power supply, data interface, and whether external logging or AMR integration is required.
