Ultrasonic Flow Meter With Small & Medium Transducers
The Ultrasonic Flow Meter from ValueStore.us provides high-precision flow rate measurements across a wide range of pipe materials, including plastics and metals. Its high-temperature transducers support operation from -40°F to 320°F (-40°C to 160°C), enabling use in demanding environments. Suitable for liquids such as water, sea water, kerosene, gasoline, crude oil, propane, and butane, it covers common industrial fluids. The device supports various pipe materials like carbon steel, stainless steel, copper, PVC, aluminum, and more, making it a flexible option for mixed-material piping systems. Typical applications include process cooling loops, chemical plants, and fuel transfer lines.
Ultrasonic Flow Meter, TUF-2000B With TM-1 Sensor
The TUF-2000B flow meter emphasizes bidirectional measurement and flexible installation options. Its core metering chip supports forward and reverse flow readings, with three measurement methods: wall mounting, inline insertion, and inline placement. It includes an inner SD card for pre-set data storage, with the option to record or not, depending on user needs. This versatility suits facilities needing reliable logging and adaptable installation in space-constrained environments.
VTSYIQI Portable Digital Ultrasonic Flow Meter
This portable meter targets water flow measurements on DN25–700 mm pipes, with a temperature range from -40 to 90°C. It ships with TS-2 and TM-1 transducers, 5m cables, a metal clamp fixture, an aluminum case, a ruler, adapters, and data line. A notable caveat is the need to apply a coupling agent (silica gel substitute) due to shipping regulations, which is required for signal transmission. The device’s portability makes it ideal for temporary installations, field surveys, or situations requiring quick on-site measurements.
NSF Certified YoLink FlowSmart All-in-One Meter
YoLink’s FlowSmart integrates an ultrasonic meter with a motorized shutoff valve for potable water applications. It offers NSF certification, multiple parallel pipe size options (1/2″ to 2″), real-time leak detection, and an offline control capability through device-to-device rules. The system supports LoRa long-range communication and a 10-year battery life, along with an ecosystem of 80+ devices. This combination provides resilience in networked or remote installations where continuous monitoring and rapid shutoff are essential.
NSF Certified YoLink FlowSmart All-in-One Meter (Hub Included)
This variant mirrors the FlowSmart all-in-one concept with a hub and the same NSF-certified ultrasonic sensing and auto shutoff capabilities. It supports a broad range of pipe sizes from 1/2″ to 2″ and includes scheduling and alert features for leak detection and abnormal usage. The offline functionality ensures critical shutoffs can operate without internet connectivity, maintaining safety and control when networks are unreliable.
YoLink FlowSmart 3/4″ All-in-One Meter
This 3/4″ version provides the same all-in-one functionality with a compact footprint suitable for smaller services or retrofit projects. It includes a NSF-certified ultrasonic meter and motorized shutoff, with resilient offline operation and LoRa connectivity to support longer-range monitoring across facilities. Operators can leverage the device ecosystem for scalable water management in residential, commercial, or industrial settings.
HFBTE Ultrasonic Flow Meter With TS-2 Transducer
HFBTE’s flow meter focuses on versatile installation options for DN25–100 mm pipes and supports liquids like water, seawater, oil, and more. It accommodates wall mounting and two DIN-rail mounting methods. The unit’s user guidance notes suggest straightforward installation and broad liquid compatibility, making it a practical option for compact systems, laboratories, or service manifolds that require quick deployment and flexible mounting choices.
Buying Guide: Ultrasonic Pipe Flow Meters
- Measurement method: Decide between inline, insertion, or clamp-on configurations based on pipe access, flow disturbance concerns, and required accuracy. Inline meters typically offer robust accuracy, while clamp-on meters excel in non-invasive installations.
- Pipe size and range: Confirm the meter supports your pipe diameter. Some models span small to very large diameters, while others target a narrower range.
- Transducers and installation options: Consider the transducer type (clamp-on, TM-1, TS-2, or inline sensors) and the installation method that best fits your environment (wall mounting, inline, or DIN-rail).
- Temperature and chemical compatibility: Ensure the device can operate within your liquid temperature range and handle the specific chemical properties of the fluid (corrosion, fouling, lubricity).
- Data handling: Look for data logging, SD storage, export capabilities, and offline operation. Real-time leak detection and alerts are advantageous for critical pipelines.
- Power and connectivity: Evaluate battery life (for wireless deployments), LoRa or other wireless protocols, and whether a hub or gateway is required for networked deployments.
- Certification and safety: NSF certification and compliance can be important for potable-water applications and regulated environments.
- Maintenance and support: Check sensor longevity, calibration needs, replacement parts, and manufacturer support for field serviceability.
