EnSyuSuMa Tuf-2000B Series Ultrasonic Flow Meter
The EnSyuSuMa Tuf-2000B system supports DN20-700mm with TS-2 transducers and TM-1 transducers, offering 4-20mA, octal pulse, and relay outputs. Best for: projects requiring robust, multi-transducer installations with a single host unit. Limitations: dependence on a multi-part kit means a longer setup and potential inventory considerations for spare parts.
Bonvoisin Handheld Ultrasonic Flow Meter
Bonvoisin’s S1+M2 sensor handheld unit is designed for clamped-on measurement with data logging and software access. Best for: field technicians and contractors needing non-destructive, quick assessments on DN15-700mm lines. Cautions: data download requires software access; the device may require extra setup for non-standard fluids.
CGOLDENWALL Handheld Ultrasonic Flowmeter
CGOLDENWALL’s system uses S1+M2 transducers for quick pipe measurements and includes a broad DN range. Best for: users needing a portable device that works with copper and PVC pipes (DN15-700mm). Note: couplant is not included; users may substitute butter, petroleum jelly, or dish soap. Suitable for: water, seawater, and various hydrocarbons with compatible pipes.
FXEIPOL Ultrasonic Flow Meter with TS-2 & TM-1
FXEIPOL’s unit emphasizes high quality construction and universal applicability for liquids including water. Best for: installations requiring reliable performance with DN20-700mm and a TUF-2000B host. Limitations: basic data handling features; advanced data analysis may require external software.
HYYKJ-US Ultrasonic Flow Meter IP67 (TUF-2000B Series)
HYYKJ-US offers IP67-rated protection, suitable for outdoor or moisture-prone environments. Best for: long-term outdoor installations or harsh settings needing durable housing. Caution: ensure proper installation to maximize the bi-directional measurement and three-method options without disrupting flow.
InnaMall TUF-2000B Family Ultrasonic Flow Meter
InnaMall’s TUF-2000B family emphasizes a fixed digital meter with TS-2 & TM-1 transducers, DN20-700mm, and an LCD display. Best for: installations requiring a clear LCD interface and robust transducer options. Caution: check compatibility with your fluid type and installation method to avoid measurement disruption.
Buying Guide
What to consider when choosing an ultrasonic flow meter
- Pipe size and compatibility: Confirm DN range and pipe materials (copper, PVC, steel). Some meters distinguish S1 and M2 transducers for different DN segments.
- Measurement method: Wall mounting, inline, or insertion options affect installation effort and pressure drop. Choose based on installation constraints and maintenance needs.
- Fluid compatibility: Ensure the device handles your liquid type (water, seawater, oil, alcohol, wastewater). Some models specify non-contact measurement suitable for long-term durability.
- Output and data: 4-20mA, pulse, and relay outputs help integrate with existing systems. Consider built-in data loggers for offline analysis.
- Durability and environment: IP ratings (IP67/IP68) protect against dust, water, and corrosion. Outdoor installations benefit from rugged housings.
- Power and connectivity: Check voltage range and available interfaces (RS232, USB, software access). Some units require external software for data extraction.
Practical comparison
- Best for multi-transducer fixed installations: EnSyuSuMa Tuf-2000B kit.
- Best for portable field work: Bonvoisin or CGOLDENWALL handheld units.
- Best for water supply and general liquids: FXEIPOL and HYYKJ-US IP67 units.
- Best for outdoor harsh environments: HYYKJ-US IP67 model, or any IP-rated variant.
FAQ
- What is an ultrasonic liquid flow meter? It uses sound waves to measure the velocity of a liquid in a pipe, translating that into flow rate without direct contact with the fluid.
- Do I need corrosion resistance? If your liquid is seawater or chemically aggressive, choose IP-rated housings and corrosion-resistant materials.
- Can these meters be installed without cutting pipes? Yes, many clamp-on or insertion options allow non-destructive installation.
- Is data logging included? Some models include internal storage; others require external software for data download.
- What fluids can be measured? Most models handle water, seawater, oils, alcohols, and wastewater; verify specific fluids and temperature ranges in specs.
- Are couplants required for all meters? Some handheld units use direct contact; others specify that couplants are not included or needed for certain installations.
