Ultrasonic Flow Meter With High Temperature Transducers
The ValueStoreUS ultrasonic flow meter is designed for accuracy in a wide range of liquids and pipe materials. Claimed accuracy reaches 99%, making it a strong choice for precise monitoring in process lines. The system supports high-temperature transducers capable of operating from -40°F to 320°F (-40°C to 160°C), enabling reliable measurements in hot liquids or heated pipes. It works with many common liquids such as water, seawater, kerosene, gasoline, fuel oil, crude oil, propane, and butane, and is compatible with materials including carbon steel, stainless steel, cast iron, copper, PVC, aluminum, and more. Installation is non-destructive, and the device can measure flow in both plastic and metallic pipes. This model suits industrial facilities needing robust performance across challenging thermal environments.
- High accuracy: up to 99%
- Wide temperature range: -40°F to 320°F (-40°C to 160°C)
- Multi-material compatibility: plastic and metal pipes
- Supports a variety of liquids from water to fuels
- Non-destructive installation
Application notes: Ideal for process lines where accurate, continuous flow data is essential, and where temperature conditions can be demanding. The device is suitable for installations in chemical plants, water treatment, and oil/gas facilities where both metallic and polymer piping are present.
Oxygen Flow Meter For Gases
The JIAWANSHUN oxygen flow meter targets gas applications, focusing on detecting and controlling oxygen flow. It measures a single-phase, non-pulsating flow in the range of 0.1 to 1.5 LPM, making it suitable for controlled oxygen environments or small-diameter gas lines. The copper connector supports secure connections in laboratory or industrial gas lines. While compact and straightforward, this meter is best suited for oxygen-specific processes or systems requiring precise, low-flow gas measurement and regulation rather than universal liquid flow duties.
- Flow range: 0.1-1.5 LPM
- Designed for oxygen and related gases
- Copper connector for secure plumbing
- Non-pulsating flow measurement
Considerations: Ensure compatibility with your gas type and the required precision for your control loop. This model excels in clean, low-flow gas lines where oxygen concentration needs tight regulation.
Portable Clamp-On Ultrasonic Flow Meter
The Bonvoisin handheld ultrasonic flow meter is built for flexibility and quick deployment. It clamps onto pipes (DN15-700mm or 1/2-28″) without cutting or interrupting service, enabling non-destructive measurements in seawater, alcohol, and various industrial effluents. The device includes S1+M2 sensors for quick setup and a control unit for data capture. It features an internal data logger capable of storing up to 2000 measurement records, with options to download data for post-processing. Two key strengths are portability and the ability to obtain real-time and historical flow data without pipeline downtime.
- Non-destructive, clamp-on installation
- Internal data logger (up to 2000 records)
- Real-time and historical data access
- Supports DN15-700mm (1/2-28″) pipes
Application notes: Suitable for field tests, temporary monitoring, and on-site verification in water services, chemical processing, and environmental monitoring where quick setup and mobility matter.
Digital Ultrasonic Flowmeter With TS2 Transducer
The TUF-2000M-TS-2 is a digital ultrasonic flowmeter module featuring TS2 transducers for DN15-100mm pipes. Its temperature operation range spans from -30°C to +90°C, enabling measurements in common industrial fluids and moderate temperature variations. The unit is designed as an RTU/flow meter module, suitable for integration into larger control systems and remote monitoring setups. The TS2 transducers offer robust sensing performance, while the overall package targets applications requiring reliable data in compact piping configurations.
- DN15-100mm measurement range
- TS2 transducers for reliable sensing
- Temperature range -30°C to +90°C
- Digital flowmeter module suitable for RTU integration
Considerations: Ideal for OEMs and plant integrations where a modular ultrasonic flow solution is preferred, particularly in spaces with limited pipe routing and a need for remote telemetry.
IP67 Ultrasonic Flow Meter For Liquid Transfer
The Ultrasonic Flow Meter from WEHAVEFUN is designed for liquid flow in DN50-700mm pipes with IP67 protection. It supports bidirectional measurement and can handle a range of liquids such as water, seawater, sewage, oil, and alcohol. The DN sizing and bi-directional capability make it versatile for municipal, industrial, and environmental applications where rugged outdoor or wash-down environments are expected. Its robust enclosure helps protect the electronics in harsh conditions while enabling precise flow data.
- DN50-700mm pipe range
- Bidirectional flow measurement
- IP67 rated enclosure
- Suitable for water, seawater, sewage, oil, and alcohol
Considerations: This meter fits installations requiring durable protection against dust and water exposure, and where large-diameter piping is involved. It is particularly appropriate for municipal water systems or industrial facilities with challenging environments.
Buying Guide: Key Considerations And Comparisons
When choosing an ultrasonic flow meter, several factors influence performance and value. Consider pipe size compatibility, transducer type (S1/S2 or TS2), and whether the device is clamp-on or inline. Clamp-on meters are non-destructive and quick to install but may be sensitive to pipe surface conditions and alignment. Inline meters can offer higher stability for long-term monitoring but require pipe access and potential shutdowns for installation.
Accuracy and repeatability matter for process control. Look for stated accuracy (often around 1%), linearity, and repeatability values. Temperature and pressure ranges should align with your operating environment and the fluids being measured. For hazardous or corrosive liquids, ensure the housing and materials meet appropriate ratings, such as IP67 for outdoor or wash-down environments.
Data handling capabilities are another consideration. Internal data loggers, real-time display, CSV export, and RS232/RS485 or digital outputs support integration with SCADA or PLC systems. If you need remote monitoring, confirm available communication options and any required software or licensing.
Pipe material and liquid type can dictate sensor suitability. Some meters work well with water, seawater, and oils, while others focus on specific gases or oxygen content. For facilities with multiple pipe sizes, consider meters that support a wide DN range or have modular transducers to cover both small and large lines.
Installation and service expectations vary. Non-destructive, clamp-on meters minimize downtime, while inline systems demand proper routing and potential system adjustments. Maintenance considerations include sensor cleaning, calibration frequency, and battery life (for portable units).
In summary, choose a model that aligns with your pipe size, liquid type, installation constraints, data needs, and environmental conditions. The five options above illustrate a spectrum of capabilities—from compact, portable meters for rapid field work to rugged, IP-rated units suited for outdoor or harsh environments. The best choice will balance accuracy, ease of use, and integration with your control systems.
