Box type ultrasonic flowmeter
The box type ultrasonic flowmeter is a device developed by our company for measuring water level and flow rate in open channels. The box type ultrasonic flowmeter is precision machined with accurate internal dimensional parameters. The entire measurement and calculation process is independent of channel parameters, and
there is no need for on-site calibration after factory calibration. The accuracy is independent of channel parameters. The box type ultrasonic flowmeter calculates the
flow velocity of the medium by measuring the time difference between the forward and backward flow of ultrasonic waves in the medium based on the principle of
time difference. The average flow velocity of the fluid can be measured through multiple pairs of internal ultrasonic transducers. The fluid area can be calculated
using an electronic water gauge and a set box width, and the instantaneous flow rate, cumulative flow rate, and other data information can be finally calculated using
the principle of velocity area method.
The human-machine interface is rich and easy to use.
Supports RS485 communication,making integration with remote data management systems more convenient.
The comprehensive use of frequency difference and time difference measurement techniques, automatic compensation of sound velocity, and timeresolution of 22 picoseconds effectively avoid zero drift and improve the accuracy of small flow measurement.
The host and probe types are diverse and can be used in combination according to on-site requirements, which can meet the installation and measurement needs of special environments.
Supports input methods such as AC220V, DC12V, and solar power supply.
Supports multi-channel measurement(4-24 channels), which can effectively improve the measurement accuracy and reliability of the instrument in complex fluid states.
