Digital Notch Apparatus with Ultrasonic Level Sensor

数字式堰流实验装置(超声波液位传感器)

Field gauging stations use ultrasonic level sensors, and hydrometry students should calibrate one against a hook gauge. A 0–250 mm ultrasonic sensor with 0.5 mm resolution and a DN32 electromagnetic flowmeter log into software that fits rating curves. The 1500 mm clear channel takes three thin-plate notches and a broad-crested block.
