Abstract
The utility model provides an ultrasonic flowmeter which comprises a shell, wherein a support is arranged in the shell, a reflection mirror is arranged on the support, and the ultrasonic flowmeter is characterized in that four transducer installation holes perpendicular to the shell are formed in the shell, a transducer is arranged in each transducer installation hole, and the reflection mirror is provided with two reflection faces corresponding to two transducers respectively. Due to the two faces of the reflection mirror, the problem that the amount of water flow in the two sides is not even after water flow passes through the reflection mirror is avoided, and the ultrasonic flowmeter has the advantages of being simple in structure, low in production cost, convenient to machine, accurate in measurement, high in disturbance rejection performance, and the like.
Description
Technical field
The utility model relates to a kind of ultrasonic flow meter.
Background technology
Existing ultrasonic flow meter with small aperture has the following disadvantages: the one, and existing ultrasonic flow meter on the market, particularly the following ultrasonic flow meter of DN100 bore mostly adopts single to transducer, in case any one transducer damages, whole flowmeter can't measure.The 2nd, the catoptron of part ultrasonic flow meter is Lens, requirement is arranged on the center of whole pipeline, because this single-sided structure causes current after the flowmeter reflecting optics, easily form one side current many and slow, current are few and anxious on one side, but flowmeter often can only measure monolateral water velocity, thereby causes measuring coarse result.The 3rd, the catoptron of most of Multi reflection ultrasonic flow meter is Lens, requirement is arranged on one side of whole pipeline, while due to this single-sided structure, causing current through flowmeter, all on one side of whole pipeline and because catoptron needs the concave surface placement, easily pile up dirt on catoptron and the tube contacts position very large easy formation turbulent flow of fluctuating and eyeglass, thereby cause measuring coarse result.
The utility model content
The purpose of this utility model provides a kind of simple in structure for above-mentioned situation exactly, and low cost of manufacture is easy to process, measures accurate ultrasonic flow meter.The purpose of this utility model can realize by following scheme: a kind of ultrasonic flow meter table body, comprise housing, the housing the inside is provided with support, catoptron is housed on support, it is characterized in that being provided with four transducer mounting holes vertical with housing on housing, a transducer is installed in each transducer mounting hole, and described catoptron is provided with two reflectings surface, respectively corresponding two transducers.Because catoptron has two sides, current can not occur that after catoptron current are many on one side again, on one side the few problem of current.The utlity model has simple in structurely, production cost is low, and is easy to process, metering accurately, the vulnerability to jamming high.
