HRF600 24GHz Radar Flow Meter With Large Range

Radar flow meter with 24GHz is designed based on the measurement principle of frequency modulated continuous wave (FMCW). It can not only be used in a range of 40 meters, but also can measure speed and distance. Equipped with automatic recognition of water flow direction and built-in vertical angle correction function, it can be used for water level, velocity or flow measurement of other types of water treatment such as rivers, reservoir gates or sewers.

Application :

● River water level monitoring

● Reservoir flood control system

● Ecological discharge flow

● Monitoring of flow rate of agricultural water channels

● Sewage discharge control

0124GHz frequency modulated continuous wave (FMCW), and output measurement data of flow velocity, water level, and flow rate at the same time.
02Non-contact measurement and IP68 waterproof (lightning protection design), not affected by bad weather and virus factors.
03With Bluetooth parameter adjustment function, it supports mobile phone APP to wirelessly configure and maintain the device on-site.
04Optional RTU function to support remote upgrade and remote maintenance of equipment.
