Handheld ultrasonic flowmeter utilizes low-voltage, multi-pulse time difference principle, the use of high-precision and ultra-stable double-balanced differential signal transmitter, differential receiver digital detection technique to measure the downstream and upstream directions sonic transit time flow rate calculated according to the time difference . With good stability, zero drift, high accuracy, wide turndown ratio and strong anti-jamming features.
When the ultrasonic beam propagation in the liquid, the liquid flow will produce small changes in the propagation time, the propagation time is proportional to the fluid flow rate variation, zero flow, the two acoustic sensors required for transmitting and receiving exactly the same time (the only actual measured zero flow technology); medium flow, countercurrent flow of the acoustic transmission time is greater than the direction of acoustic transmission time
