1Equipment Composition

IIEquipment principle

The product has three functions: measuring average flow velocity, measuring water depth, measuring water temperature, and can display cross-sectional flow rate.

Among them, temperature probes are used for water temperature measurement, high-precision pressure sensors or ultrasonic sensors are used for water depth measurement, and flow velocity measurement is carried out through

The ultrasonic probe (transducer) emits and receives ultrasonic signals and performs corresponding calculation and processing to obtain them.

LayeredFlow velocity measurement:The measurement of flow velocity is carried out by using an ultrasonic probe (transducer) to emit two ultrasonic waves at intervals of a few seconds for cross-sectional analysis

ScanDraw and save the results of two scans, and obtain the velocity of particles in each layer by comparing their positions.
