1. Overview
The BT7320 Hand-held Radar Flow Meter is a lightweight, ultra-portable, and non-contact water velocity measuring instrument designed for complex and rugged field environments. Equipped with a 24GHz planar array radar and self-developed velocity calculation algorithms, the BT7320 delivers instant, accurate flow speed readings up to 100 meters away. Featuring an IP68 protection level, dual-mode power supply, and automatic vertical tilt compensation, it is an ideal tool for river surveys, sewage pipe monitoring, flood emergency response, and oceanographic research.
2. Functional Features
- Compact and portable design, comfortable to hold, suitable for non-contact measurements in complex environments.
- Customizable LCD screen and display program, providing real-time flow velocity, average flow velocity, tilt angle data, and other information during the measurement process.
- Storage of over 1000 measurement results, allowing for data retrieval, deletion, and transmission at any time.
- Supports bracket fixation and Bluetooth configuration, unaffected by harsh weather conditions, providing more comfortable and convenient operation.
- Ultra-low power consumption design, dual-mode power supply (rechargeable lithium battery/dry battery), ensuring all-weather response for emergency measurements.
- Self-developed core measurement module and velocity calculation algorithm, adapting to various complex wave environments, ensuring stable and reliable flow velocity measurements.
