Description

Technical Field

[0001] The utility model relates to the technical field of open channel flow measurement, in particular to an open channel flow measurement device with a pluggable transducer group. Background Art

[0002] Ultrasonic box-type open channel flowmeter can measure the flow velocity and liquid level parameters of the fluid, process the flow velocity and water level data, and integrate and calculate the instantaneous flow rate and other data. This product is based on the time difference method. It uses an ultrasonic transducer to send ultrasonic signals in the downstream and upstream directions of the fluid. The transducer receives the ultrasonic signal, obtains the time difference information, and the integrator calculates the flow velocity information. The ultrasonic level meter emits a high-frequency ultrasonic pulse from the transducer, which is reflected on the surface of the measured medium. The reflected echo is received by the transducer and converted into an electrical signal. The ultrasonic pulse propagates at the speed of sound waves. The time interval from the emission to the reception of the ultrasonic pulse is proportional to the distance from the transducer to the surface of the measured medium.

[0003] The transducer module of the existing ultrasonic box-type open channel flowmeter is fixedly installed, that is, the transducer module cannot be disassembled separately. When the transducer module is damaged or needs maintenance during use, the box can only be disassembled as a whole, which is very inconvenient during use. Moreover, during the dry season, since the transducer module cannot be disassembled, the transducer module is often lost, causing certain economic losses to the user unit.

[0004] Based on the above problems, the applicant has improved the existing ultrasonic box-type open channel flow meter and proposed an open channel flow measurement device with a pluggable transducer group. Utility Model Content
