Description
Technical Field
The invention relates to the field of aquaculture, in particular to an ultrasonic flow sensor for aquaculture.
Background
It is well known that ultrasonic flow sensors consist essentially of a housing cavity and a transducer. Wherein, a pair of transducers are fixed in the housing cavity at a certain interval. When the circulating medium flows through the flowmeter, under the action of an external circuit, the difference of the speeds of the ultrasonic pulse forward flow and reverse flow is measured through the sensing of the transducer to reflect the flow speed of the fluid, so that the flow and the mass are measured.
The existing ultrasonic flow sensor has low measurement accuracy in the gentle water flow of aquaculture, the service life of the ultrasonic transducer is short, ultrasonic pulse cannot be effectively sensed, and measurement errors are large to be improved.
