Abstract
The utility model discloses an ultrasonic flowmeter which comprises a shell (1), an oscillometer (2), a circuit board and an ultrasonic probe (3), wherein the oscillometer (2) is arranged on the shell (1); the circuit board is arranged in the shell (1); the oscillometer (2) and the ultrasonic probe (3) are connected with the circuit board; the circuit board is formed by common connection of a power module (4), a signal conversion module (5), a signal processing module (6) and a display module (7) thereon. The ultrasonic probe (3) is used for measuring the flow rate and flow velocity of a pipeline; an electric signal obtained by measurement is converted into a digital signal by the signal conversion module (5), the digital signal is processed by the signal processing module (6), and then the oscillometer (2) is used for displaying the flow rate, the flow velocity and the signal waveform of the ultrasonic probe. By utilizing the flowmeter, the flow rate, the flow velocity and the signal waveform of the ultrasonic probe can be observed on site, so that an operating worker can know the running situations of equipment in time, and the working efficiency is improved.
Description
Technical field
The utility model relates to flowmeter, is specifically related to a kind of ultrasonic flow meter.
Background technology
As everyone knows, flowmeter is used for the measurement of ducted every physical parameter, existing flowmeter can only be realized the teletransmission of duty electric signal, and the operator can't observe the signal waveform of flow in the pipeline, flow velocity and ultrasonic probe at the scene, can not grasp the ruuning situation of equipment timely, bring uncertain factor to commercial production, influence work efficiency.
Summary of the invention
The purpose of this utility model is: a kind of ultrasonic flow meter is provided, and this flowmeter just can be observed the signal waveform of flow, flow velocity and ultrasonic probe at the scene, allows the operator grasp the ruuning situation of equipment timely, increases work efficiency.
The technical scheme that its technical matters that solves the utility model adopts is: this flowmeter comprises housing, oscillograph, circuit board and ultrasonic probe, oscillograph is installed on housing, mounting circuit boards in housing, oscillograph and ultrasound wave are visited and are connected circuit board, and circuit board is connected in the circuit board altogether by power module, signal conversion module, signal processing module and display module and forms.
The utlity model has and give advantage:
1, an oscillograph is installed in ultrasonic flow meter, oscillograph can show the waveform that sends, the waveform of acceptance and the waveform that reflects, and allows measure more that visualize shows.
2, just can make things convenient in measure field and see ducted every physical parameter intuitively, no matter operating personnel are in the pulpit or can both grasp the ruuning situation of equipment at the scene timely.
3, adopt the MSP430F149 low-power scm of TI, high-performance, low price, high reliability, powerful are disturbed its frequency conversion that more can adapt in the industrial environment, reach stable, correct work.
4, the utility model measure linear degree is better than 0.5%, and repeatability precision is better than 0.2%, up to the time difference measurement resolution of 40 psecs make measuring accuracy reach ± 1%.
5, the auxiliary step-out time analysis software of 128 secondary data collections in each measuring period, excellent performance, video data is more stable, accurate, Linearity is better.
