F203B New-generation clamp-type Ultrasonic liquid flow meter

Measurement Range：0.03 m/s … ±12 m/s
Turndown Ratio：1:400

Characteristics

The working principle of the F203B ultrasonic flowmeter is mainly based on the propagation characteristics of ultrasonic waves in a fluid, measuring flow rate by detecting time delays. Because the ultrasonic flowmeter uses a non-contact measurement method and does not need to directly contact the fluid, it has a wide range of applications Utilizing FPGA integrated circuit technology, the algorithm integrates threshold comparison gate circuit delay methods and high-speed ADC correlation methods, achieving a measurement rate greater than 300 times per second. Compared to traditional capacitive charging algorithms with measurement rates below 50 times per second, this ensures more accurate and reliable measurement results There is also a significant improvement in the bubble tolerance within the measurement pipe diameter, with the capability to withstand continuous bubbles or impurities for up to 5 seconds The unique flip cover design hides all screws after installation, and the use of longer-lasting membrane buttons provides a more comfortable key feel
