Open Channel Radar Water Flow Velocity Meter
Video
Feature
● Non-contact, safe and low damage, low maintenance, not affected by sediment.
● Capable of measuring under high velocity conditions during flood periods.
● With anti-reverse connection, over-voltage protection function.
● The system has low power consumption, and general solar power supply can meet th e current measurement needs.
● A variety of interface methods, both digital interface and analog interface, compatible with standard.
● Modbus-RTU protocol to facilitate access to the system.
● With wireless data transmission function (optional).
● It can be independently connected to the current running urban water regime, sewage, and environment automatic forecasting system.
● Wide range of speed measurement, measuring effective distance up to 40m.
● Multiple trigger modes: periodic, trigger, manual, automatic.
● The installation is particularly simple and the amount of civil works is small.
● Fully waterproof design, suitable for field use.
Measuring Principle
The radar flow meter can perform flow detection in periodic, trigger, and manual trigger modes. The instrument is based on the principle of Doppler effect.
Product Application
