Ultrasonic Water Flow Meter with LoRaWAN – IoT PCB Water Flow Sensor for Smart Monitoring

The Ultrasonic Water Flow Meter with LoRaWAN is a high-performance, portable tool designed for precise water flow measurement in various pipe systems. This transfer time ultrasonic flow meter is ideal for quickly verifying the accuracy of other flow meters or for long-term data logging of flow values. With its clamp-on transducers, installation is non-invasive—no pipe cutting or tapping required—making it easy to move from one site to another. Its portability makes it the perfect choice for assessing flows across plumbing infrastructures, ensuring accurate performance of sensors, pumps, and valves.

Key Features:

• Clamp-on Design: No need for pipe alterations—simply clamp the transducers onto the pipe for hassle-free installation and mobility between sites.
• Versatile Measurement: Measures flow across a wide range of pipes from 1" to 48" (25mm to 1200mm), compatible with materials like carbon steel, stainless steel, PVC, and more.
• Highly Accurate: Provides ±1% measurement accuracy with a flow range of ±0.03 ft/s to ±40 ft/s (±0.01 m/s to ±12 m/s).
• Portable and Convenient: Lightweight and easy to transport, with a rechargeable lithium battery that supports up to 16 hours of continuous operation.
• LoRaWAN Connectivity: Equipped with IoT capabilities, enabling remote monitoring and data logging for smart infrastructure management.

Measuring Principle:

The meter uses transfer time technology, where the ultrasonic signal is transmitted and received through the flowing liquid. The difference in upstream and downstream transit times is used to calculate the flow rate and velocity, providing accurate real-time data.
