Abstract

The invention discloses a non-contact ultrasonic flow velocity meter. The non-contact ultrasonic flow velocity meter comprises an ultrasonic transducer, an electronic circuit and a flow display and accumulation system, wherein the ultrasonic transducer comprises an ultrasonic emission transducer and an ultrasonic receiver; the ultrasonic emission transducer is used for converting electric energy into ultrasonic energy, and emitting the ultrasonic energy to the detected flow; the ultrasonic receiver is used for receiving ultrasonic signals and sending the ultrasonic signals to the electronic circuit; the electronic circuit comprises an emission unit, a receiving unit and a signal processing unit; the receiving unit is used for receiving the ultrasonic signals sent from the ultrasonic receiver and sending the ultrasonic signals to the signal processing unit to process the signals; and the emission unit sends the signals processed by the signal processing unit to the flow display and accumulation system. As the non-contact ultrasonic flow velocity meter installs the ultrasonic emission transducer and the ultrasonic receiver on the outer wall of a pipeline to be detected, flow detection when the water flow is opened wide can be performed, and no detection elements are required to be installed in the flow while the flowing state of the flow is not changed.

Description

technical field

[0001] The invention relates to a non-contact ultrasonic water flow velocity meter and a non-contact flow velocity detection method. Background technique

[0002] The current industrial flow measurement generally has the problem of large pipe diameter and large flow measurement difficulty. This is because the general flowmeter will bring difficulties in manufacturing and transportation with the increase of the measurement pipe diameter, increase the cost, increase the energy loss, These disadvantages are inconvenient to install. Since the existing ultrasonic flowmeter needs to install probes at different depths in the measurement of rivers and open channels, it leads to inconvenient installation, low accuracy of installation position, inconvenient debugging and maintenance, and large measurement errors. Contents of the invention

[0003] The purpose of the present invention is to provide a non-contact ultrasonic water flow velocity meter and a non-contact ...
