Abstract
The invention relates to an ultrasonic flowmeter, which comprises a measurement duct, wherein the measurement duct is internally provided with an ultrasonic emitter and an ultrasonic receiver which are used for measuring the flow rate of fluid; the ultrasonic emitter and the ultrasonic receiver are connected with an intelligent processor; the ultrasonic emitter and the ultrasonic receiver are positioned at the lowest point of the measurement duct, cling to the inner wall of the measurement duct, and are positioned on the same axis. After the structure is adopted, under the state of non-full-package, ultrasonic waves are always spread in the fluid in the emission process and the reception process, and the measurement accuracy is ensured; the ultrasonic emitter and the ultrasonic receiver are oppositely positioned on the same axis, so the influence of a pipe wall for reflecting the ultrasonic waves is reduced to the maximum extent; a liquid level sensor is used for measuring the specific position of the liquid level, and an intelligent processor is used for synthesizing a ultrasonic wave signal and a liquid level signal for more accurately obtaining a flow rate value.
Description
Technical field
The present invention relates to a kind of flowmeter in mechanical field, especially relate to a kind of ultrasonic flow meter.
Background technology
Ultrasonic flow meter is by the test fluid instrument in order to measuring flow to the work of supersonic beam (or ultrasonic pulse) that flows.Ultrasonic flow meter can make that instrument measurement signal is more stable, antijamming capability is strong, metering is more accurate.Can be widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.Mainly, when ultrasonic beam is propagated in liquid, flowing of liquid will make the travel-time produce subtle change to the principle of ultrasound flow, and the variation in its travel-time is proportional to the flow velocity of liquid.At present, most ultrasonic flow meter is only suitable for using under full packages state, fluid in flowmeter is under non-full pipe state, especially the velocity of propagation of ultrasound wave in air and fluid is different, in the situation that adopting existing flowmeter, can cause ultrasound wave part part in fluid to be propagated in air, can make flow measurement inaccurate.
Summary of the invention
Technical matters to be solved by this invention is to provide and a kind ofly can under non-full pipe state, accurately measures the ultrasonic flow meter of fluid flow.
The present invention solves the technical scheme that its technical matters takes: a kind of ultrasonic flow meter, comprise measuring guide, in measuring guide inside, be provided with for measuring ultrasonic transmitter and the ultrasonic receiver of fluid flow, described ultrasonic transmitter is connected with intelligent processor with ultrasonic receiver, and described ultrasonic transmitter and ultrasonic receiver are positioned at the minimum point of measuring guide and are close to measuring guide inwall and are positioned on same axis.
Further concrete, the inwall of described measuring guide is provided with some liquid level sensors, and described liquid level sensor is connected with intelligent processor.
Further concrete, described liquid level sensor has 5, lays respectively at 10% liquid level, 30% liquid level, 50% liquid level, 70% liquid level and 90% liquid level place.
Further concrete, coated anticorrosive coat on described measuring guide inwall.
The invention has the beneficial effects as follows: after having adopted said structure, under non-full pipe state, make ultrasound wave transmit and receive process propagates all the time in fluid, guaranteed its measuring accuracy, ultrasonic transmitter and ultrasonic receiver is staggered relatively on same axis, guarantee the impact of tube wall reflection supersonic wave to drop to minimum; Can record by liquid level sensor the particular location of liquid level, by intelligent processor combined echocardiography ripple signal and liquid level signal, obtain more accurately flow value.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of ultrasonic flow meter as depicted in figs. 1 and 2, comprise measuring guide 1, in measuring guide 1 inside, be provided with for measuring ultrasonic transmitter 3 and the ultrasonic receiver 5 of fluid flow, described ultrasonic transmitter 3 is connected with intelligent processor 4 with ultrasonic receiver 5, described ultrasonic transmitter 3 and ultrasonic receiver 5 are positioned at the minimum point of measuring guide 1 and are close to measuring guide 1 inwall and are positioned on same axis, can prevent that resulting signal from being ultrasound wave transmitting signal in air and fluid media (medium), guaranteed measuring accuracy; The inwall of described measuring guide 1 is provided with some liquid level sensors 6, and described liquid level sensor 6 is connected with intelligent processor 4; Described liquid level sensor 6 has 5, lays respectively at 10% liquid level, 30% liquid level, 50% liquid level, 70% liquid level and 90% liquid level place, can place liquid level sensor 6 at diverse location, can guarantee its measuring accuracy; Coated anticorrosive coat 2 on described measuring guide 1 inwall can be used in corrosive liquids.
When using, when fluid is full packages state by measuring guide 1, ultrasonic transmitter 3 transmitting ultrasound waves in measuring guide 1, ultrasonic signal passes to ultrasonic receiver 5 places by fluid media (medium) and receives, ultrasonic transmitter 3 will transmit and pass to intelligent processor 4, ultrasonic receiver 5 passes to intelligent processor 4 by reception signal, and intelligent processor 4 processing signals draw flow value; When fluid is non-full pipe state by measuring guide 1, intelligent processor 4 receives ultrasound wave and transmits and ultrasound wave reception signal, simultaneously, the liquid level signal of being measured fluid by the liquid level sensor 6 on measuring guide 1 inwall passes to intelligent processor 4, transmitting and receiving signal and liquid level signal of intelligent processor 4 combined echocardiography ripples, can obtain flow value more accurately.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
