描述
Product Overview
Modbus Doppler flowmeter is a non-contact water level measurement instrument based on FMCW radar technology, which has the characteristics of high measurement accuracy, wide measurement range, small blind spot, easy installation, stability and reliability. It can be widely used in rivers, lakes, reservoirs, dams, water conservancy engineering, water resource management, agricultural irrigation, drainage monitoring, industrial production, environmental monitoring and other fields.
Product Principle
The Doppler flowmeter uses the principle of Doppler effect for measurement. When sound waves encounter moving objects, their frequency changes. This instrument emits sound waves and receives echoes, and the flow velocity can be obtained by calculating the frequency change.
Product Features
- High Measurement Accuracy: Using FMCW radar technology, the measurement accuracy can reach ± 1mm.
- Wide Measurement Range: The maximum range can reach 70m, which can meet the measurement needs of different scenarios.
- Small blind spot: The blind spot is only 10cm, which can effectively measure the water level at close range.
- Easy to install: Integrated design, simple installation, no need for complex settings.
- Stable and reliable:IP67 protection level, can adapt to various harsh environments.
