Ultrasonic Flow Meter With Small & Medium Transducers
The Ultrasonic Flow Meter with Small & Medium Transducers targets pipes from 0.76 to 27 inches (20 to 700 mm) and supports high-temperature operation. It claims 99% accuracy and is suitable for liquids such as water, seawater, kerosene, gasoline, fuel oil, crude oil, propane, and butane across varied pipe materials including carbon steel, stainless steel, cast iron, ductile iron, copper, PVC, aluminum, and fiberglass. This model is designed for versatile industrial applications where stable performance is critical in harsh environments.
Ultrasonic Flow Meter, TUF-2000B
The TUF-2000B model offers bi-directional metering essential for flows that may reverse under certain process conditions. It supports three measurement modes—wall mounting, insertion, and inline—allowing installation flexibility to suit different environments. An internal SD card provides optional data logging for regular results, empowering operators to review historical trends and verify system performance over time.
YoLink FlowSmart All-in-One Smart Meter YS5018
YoLink’s FlowSmart YS5018 integrates an ultrasonic water meter with a motorized shutoff valve for potable-water applications. It supports multiple pipe sizes and emphasizes real-time leak detection with auto shutoff, along with scheduling and alerting features. Notably, it can operate offline even without internet connectivity due to device-to-device control rules, providing resilience in critical water-management scenarios.
YoLink FlowSmart All-in-One Smart Meter for 3/4″ Pipes
This YoLink variant mirrors the all-in-one concept with a motorized shutoff valve and ultrasonic metering for potable water on 3/4″ pipelines. It adds real-time leak detection and offline operation, making it suitable for properties seeking automated water control with remote alert capabilities while maintaining functionality during network outages.
Ultrasonic Flow Sensors DN80-DN500
The CIXIFM split ultrasonic flowmeter measures low-viscosity liquids such as water, fuel oil, and diesel within DN80 to DN500 mm pipes. It features RS485 communications and 85-264 VAC power options, emphasizing straightforward installation and operation. The model positions itself as a cost-effective option with solid after-sales service for industrial water or fluid monitoring tasks.
Buying Guide: Key Considerations For Choosing An Ultrasonic Water Meter
- Pipe size and installation method: Ensure the meter supports your pipe diameter and the preferred installation method (inline, insertion, or clamp-on).
- Medium compatibility: Most water-focused meters handle clean water and common fluids; confirm tolerance for temperature, pressure, and potential contaminants in your system.
- Measurement direction and accuracy: Bi-directional capability matters for recirculating or variable-flow systems; check stated accuracy and repeatability.
- Data storage and connectivity: Decide between built-in logging, SD storage, offline operation, and online connectivity (LoRa, RS485, or Ethernet) based on monitoring needs.
- Power and maintenance: Consider battery life, power options, and sensor maintenance requirements, especially for remote or hard-to-access installations.
- Regulatory and certification relevance: NSF or other certifications can matter for potable-water applications and regulatory compliance.
- Portability vs. fixed installation: Portable handheld meters suit temporary measurements; fixed meters offer continuous monitoring and automation integrations.
For system planners, comparing these meters involves assessing reliability in pulsating water systems, compatibility with existing sensors, communication protocols, and the availability of automatic shutoff or alert features for real-time management. The selected options cover a range of use cases—from portable field checks to integrated, smart-water solutions—allowing you to align your choice with project scope, budget, and monitoring requirements.
