Product Details

The GCL-400 radar flow meter is a new 24G radar product launched by Huazhi Gannchuang IoT Technology Co., Ltd. This instrument uses a K-band planar microstrip array antenna, which concentrates energy and has low power consumption; it integrates functions such as vertical angle compensation, flow velocity filtering algorithm, signal strength detection, RS485/RS232 communication, and wireless communication; the non-contact radar flow measurement method is unaffected by temperature and air pressure when measuring speed, the equipment is not corroded by sewage, is unaffected by sediment, is less affected by water damage, has simple civil engineering, and is easy to maintain; the special antenna design makes the power consumption ultra-low, greatly reducing the power supply requirements. It is especially suitable for installation in places where long-term monitoring of flow velocity is required.

Features

Non-contact, safe and low-loss, low maintenance, unaffected by sediment
Capable of measurement under high flow velocity conditions during flood periods
Has reverse connection and lightning protection functions
Low system power consumption, generally solar power can meet the needs of flow measurement
Multiple interface types, including both digital and analog interfaces, for easy integration into various systems
Wireless transmission function (optional), data can be wirelessly transmitted to over 3.5km
Wide speed measurement range, measurement distance up to 40m
Multiple trigger modes: periodic, trigger, query, automatic
Installation is particularly simple, with minimal civil engineering required
Fully waterproof IP68 design, suitable for outdoor use

Application Areas

Geological disaster early warning monitoring
Rivers, water resource monitoring
Hydrological measurements of rivers, canals, flood control, etc.
Environmental sewage discharge, underground sewer network monitoring
Urban flood control, mountainous area rainstorm flood monitoring, etc.
