Product Description

1. Description

JW-RD-60(HJ01) handheld radar current meter is a portable non-contact flow velocity measuring instrument designed for rivers, channels, flood control, hydrological surveys and wastewater monitoring. Using 24 GHz radar technology, it measures surface water velocity without touching the water, helping users work safely in fast-flowing, polluted or difficult-to-access sites.

With a compact handheld design, built-in display, Bluetooth connection, IP67 protection and one-button operation, this radar flow meter is suitable for field teams that need quick, accurate and safe water velocity measurement.

2. Product Overview

JW-RD-60(HJ01) Handheld Radar Current Meter is designed for fast and safe water surface velocity measurement in natural and engineered water environments. It uses microwave radar sensing to measure flow velocity without direct contact with water, making it especially suitable for flood monitoring, river flow surveys, drainage channels, sewage outlets and other sites where contact measurement may be unsafe or inconvenient.

According to the brochure, the RD-60 is small in size, lightweight, easy to operate and powered by batteries. It does not require external cables or underwater probes during measurement, reducing field operation complexity. The device is equipped with an integrated tilt angle sensor and supports automatic correction of vertical and horizontal angles, improving measurement accuracy in handheld field use.
