Description
Technical field
The utility model relates to aquaculture field, particularly relates to ultrasonic flow sensor used for aquiculture.
Background technology
As everyone knows, ultrasonic flow sensor is primarily of shell cavity and transducer composition.Wherein, a pair transducer is fixed in housing chamber at a certain distance.When circulatory mediator flows through flowmeter, under outside circuit function, the difference being flowed and flow against the current hourly velocity by the sensing measurement ultrasonic pulse of transducer downstream reflects the flow velocity of fluid, thus measures flow, quality.
Existing ultrasonic flow sensor measuring accuracy in the mild current of aquaculture is not high, and ultrasonic transducer is shorter for serviceable life, cannot effective sensing ultrasonic pulse, causes measuring error comparatively large, haves much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure simple, long service life, the ultrasonic flow sensor used for aquiculture that measuring accuracy is high.
For realizing the utility model object, provide following technical scheme: a kind of ultrasonic flow sensor used for aquiculture, comprise measuring tube and be installed on two ultrasonic transducers of the symmetry in the tube wall mounting hole of measuring tube two ends, it is characterized in that ultrasonic transducer comprises housing, vibrating reed is disposed with in housing, piezoelectric ceramics, circuit board, housing comprises the conical section of direct tube section and end, described conical section surface offers spiral groove, the conical section of two ultrasonic transducers is all towards the measuring tube two ends mouth of pipe, conical section central axis is lower than measuring tube central axis, the fair water fin under being tilted to is provided with in the mouth of pipe of measuring tube two ends, fair water fin end-to-end distance is from conical section central axis 15mm.
As preferably, inner walls is provided with the cushion rubber layer that a layer thickness is 1 ~ 1.5mm.
As preferably, measuring tube outer tube wall is provided with draw-in groove, in draw-in groove, is connected with gauging table.
The utility model beneficial effect: be applicable to, in the mild current of aquaculture, forever to run use, the life-span is long, the ratio of performance to price is high, operating cost is low, and structure is simple, precious materials use amount is few, and production cost is low, simple to operate, easy for installation, save manpower.
