What are the full-scale calibration methods for Ecolor ultrasonic flowmeters and visual radar level meters?
Ultrasonic flowmeter and radar level meter full-scale calibration uses standard flow methods and reference plane establishment with multi-point calibration for accuracy
Full-scale calibration of Ecolor ultrasonic flowmeter series and visual radar level meters is essential for ensuring measurement range accuracy across the entire operating spectrum. For ultrasonic flowmeters, full-scale calibration typically employs the standard flow method, adjusting instrument parameters under known flow conditions to match displayed values with reference standards, with recommended calibration points at 20%, 50%, and 80% of full scale.
Visual radar level meter full-scale calibration requires establishing an accurate measurement reference plane using standard level gauges or laser ranging devices to determine actual water level heights, then inputting corresponding calibration values through the device parameter interface. Consider factors such as medium dielectric constant and temperature compensation during calibration.
Upon completion, measurement point errors should remain within ±0.5%. We recommend utilizing EC32/EC60 RTU systems for data logging and remote calibration verification to ensure long-term measurement precision. For devices ranging from DN10-DN2000 different diameters, calibration methods remain consistent, though calibration point selection requires adjustment based on specific flow ranges.
