Abstract

A dual-track ultrasonic flow measurement system is composed of a double-track ultrasonic flow meter and two sensors, wherein the upstream sensor and the downstream sensor are arranged on a pipeline and connected with the double-track ultrasonic flow meter. According to the dual-track ultrasonic flow measurement system, a Cortex-M3 kernel which is most popular at present is adopted, qualitative leaps are achieved in the aspect of measurement accuracy, the aspect of measurement stability, the aspect of communication protocols and the like. In the aspect of client operation menu, the operation is easy to conduct, therefore, complex operation of the flow meter is omitted, and no professionals are needed. The double-track measurement technique is adopted, calculation is conducted on software by a SUF-2006 series through the frequency difference method, therefore, influences of the temperature on the sound velocity are eliminated, and accuracy of the ultrasonic flow meter is greatly improved. Due to the fact that the advanced ultrasonic flow transducer is adopted, the dual-track ultrasonic flow measurement system has the advantages of being high in flow measurement accuracy, good in stability, strong in anti-interference capacity, good in flow condition adaptability and the like, and is widely used in the petroleum field, the mechanical industry field, the metallurgy field, the electric power field, the water supply and drainage field and the like.

Description

The two-channel Ultrasonic Flow-detecting System
Technical field
The utility model relates to electronic instrumentation, relates in particular to a kind of flow measurement device.
Background technology
Nowadays, ultrasonic flow meter is widespread use, but no matter existing ultrasonic flow meter is in measuring accuracy, all there are defect in various degree in Measurement sensibility, communication protocol aspect, and complicated operation, need the professional just can fitting operation, poor anti jamming capability, fluidised form bad adaptability, can not be widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.
The utility model content
The problems referred to above that exist in order to overcome the conventional ultrasonic wave flowmeter, the utility model provide that a kind of measuring accuracy is high, the two-channel Ultrasonic Flow-detecting System of good stability.
The technical scheme that the utility model adopts for achieving the above object is: the two-channel Ultrasonic Flow-detecting System, formed by two-channel ultrasonic flow meter and two sensors, upstream sensor and downstream sensor are installed on pipeline, and upstream sensor is connected the two-channel ultrasonic flow meter with downstream sensor.
Described pipeline is provided with sensor holder, and upstream sensor and downstream sensor are installed on sensor holder.
Two-channel Ultrasonic Flow-detecting System of the present utility model, on original basis, adopt current newfangled Cortex-M3 kernel, and no matter in measuring accuracy, Measurement sensibility, communication protocol etc. all has qualitative leap.On client's actions menu, simple operations, thus saved the complex operations of flowmeter, need not the professional.Adopted alliteration drive test amount technology, on software, SUF-2006 series is calculated by frequency-difference method, thereby eliminates the impact of temperature on the velocity of sound, has greatly improved the ultrasonic flowmeter precision; Adopt advanced ultrasonic flow rate transducer, have the characteristics such as the flow measurement accuracy is high, good stability, antijamming capability is strong, fluidised form adaptability is good, be widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.
Description of drawings
Fig. 1 is the principle schematic of the utility model two-channel Ultrasonic Flow-detecting System.
Fig. 2 is the utility model two-channel Ultrasonic Flow-detecting System structural drawing.
Embodiment
Sound channel Ultrasonic Flow-detecting System principle of the present utility model as shown in Figure 1, when ultrasonic beam is propagated in liquid, flowing of liquid will make the travel-time produce subtle change, and the variation in its travel-time is proportional to the flow velocity of liquid, and its relation meets following expression formula:
Figure DEST_PATH_IMAGE002
Wherein:
θ is the angle of acoustic beam and liquid flow direction;
M is the rectilinear propagation number of times of acoustic beam at liquid;
D is internal diameter of the pipeline;
Tup Travel-time for acoustic beam on positive dirction;
Tdown is the travel-time of acoustic beam on contrary direction;
ΔT=Tup?–Tdown;
Be more than the speed of a sound channel, sound channel 2 is the same.

Sound channel Ultrasonic Flow-detecting System structure of the present utility model as shown in Figure 2, formed by two-channel ultrasonic flow meter and two sensors, upstream sensor 2 and downstream sensor 1 are installed on pipeline 3, and upstream sensor 2 is connected with downstream sensor and is connected the two-channel ultrasonic flow meter.Pipeline 3 is provided with sensor holder 4, and upstream sensor 2 and downstream sensor 1 are installed on sensor holder 4.
The State selective measurements point:
Be the most simple and convenient in the installation that is arranged on all flowmeters of ultrasonic flow meter, as long as select a suitable measurement point, the pipe parameter of measurement point be input in flowmeter, then probe is bundled on pipeline and gets final product.Require the part of selecting the fluid smoothness to be evenly distributed during State selective measurements point, for guaranteeing measuring accuracy.Generally should follow following principle:
1. to select to be full of the pipeline section of fluid, as the vertical component of pipeline or be full of the horizontal pipeline section of fluid.
2. measurement point will be selected 10 times of diameters apart from upstream, and 5 times, downstream diameter is with interior even straight length, without any interference such as valves.
3. to guarantee that but the temperature of measurement point is in working range.
4 take into full account inside pipe wall fouling situation, select to measure without the pipeline section of fouling as far as possible.Really in the time of can not meeting, need fouling is thought of as lining in the hope of measuring accuracy preferably.
5. select tubing evenly dense, be easy to the pipeline section of ultrasonic transmission.
During installation, pipe parameter is inputted main frame, calculate the position that mounting distance (owing to adopting plug in sensor, direct metering system, i.e. Z mounting means are all used in suggestion) is made two sensors, mounting distance is the centre distance of two sensors.
Ultrasonic flow meter of the present utility model adopts current newfangled Cortex-M3 kernel, the performance of recent development, low price, reliability and powerful brand-new series of products.Last word, no matter in measuring accuracy, Measurement sensibility, communication protocol etc., all have qualitative leap.On client's actions menu, to facilitate the client as principle, simple operations, thus saved the complex operations of flowmeter, need not the professional.SUF-2006F2S two-channel ultrasonic flow meter is take " time difference method " as principle, measures the instrument that is full of closed circular liquid in pipe flow.It has adopted advanced multiple-pulse technology, Cortex-M3 kernel processes and error correcting technique, and alliteration drive test amount technology, on software, SUF-2006 series is calculated by frequency-difference method, thereby eliminates the impact of temperature on the velocity of sound, has greatly improved the ultrasonic flowmeter precision.Adopt advanced ultrasonic flow rate transducer, have the characteristics such as the flow measurement accuracy is high, good stability, antijamming capability is strong, fluidised form adaptability is good, be widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.
