Split type ultrasonic flowmeter
Description:
Products overview:
ZWS - 100 - f seriesSplit type ultrasonic flowmeterImported IC SMT, digital and integrated circuit is complete and improve the measuring accuracy and stability, greatly reducing the breakdown maintenance, is the introduction of advanced flow measurement technology and low cost to implement encapsulation at an organic whole, can be directly installed on the measuring point.Section one-piece flow of ultrasonic flowmeter with no moving parts, without daily maintenance, instrument of the microprocessor digital signal encoding and cross-correlation detection procedures, can provide long-term drift measurement.But for almost all clean uniform liquid flow body.
Second, the working principle:
ZWS - 100 - f seriesThe split type ultrasonic flowmeter with low voltage, pulse jet lag principle, the use of high precision and super stable double balance emission signal difference, difference receive digital detection technology to measure the direction of the downstream and upstream sound wave transmission time, according to calculate the velocity of jet lag.
When ultrasonic beam propagation in the liquid, the flow of the liquid produce small changes will make the travel time, the travel time is proportional to the liquid flow rate, the change of zero flow, two sensors in the time required to transmit and receive sound waves is exactly the same techniques for actual measurement of zero flow (*).Medium flow, the flow direction of sound wave transmission time is greater than in the direction of flow of sound wave transmission time.
