Abstract
A kind of ultrasonic open channel flowmeter is related to a kind of flow detector.The ultrasonic open channel flowmeter, fluid is divided by two parts using the triangle water retaining cover cylinder with inlet opening, the flow velocity that most fluid passes through acquisition fluid after flow rate of water flow measurement sensor, the fluid of fraction enters after triangle water retaining cover cylinder obtains water level by ultrasonic probe, and via controller obtains the flow of fluid after calculating.The device reasonable design, simple in structure, measurement is accurate.
Description
Technical field
The utility model is related to a kind of flow detector, more particularly to a kind of ultrasonic open channel flowmeter.
Background technology
Ultrasonic open channel flowmeter is to measure open channel flow rate using ultrasonic wave, is widely used in industrial wastewater discharge
Monitoring measure, existing open-channel meter is typically all single channel weir notch, and level fluctuation is larger in the more fluid of impurity,
Cause to measure inaccurate.
Invention content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of ultrasonic open channel flowmeter, it should
It is device reasonable design, simple in structure, it is easily installed and safeguards, saved a large amount of manpower and material resources.
Technical solution used by the utility model is：A kind of ultrasonic open channel flowmeter, is characterized in that, including band
There are triangle water retaining cover cylinder, ultrasonic probe, flow rate of water flow measurement sensor and the controller of inlet opening, triangle gear
Water cover cylinder is fixed on weir notch amount water installations bottom, and the triangle water retaining cover cylinder side where inlet opening is located at flow downstream side
To inlet opening is connected to be formed into water loop with triangle water retaining cover tube inner chamber, is fixed on the top of triangle water retaining cover cylinder inner wall
It is connected with ultrasonic probe, flow rate of water flow measurement sensor, the ultrasonic probe, water are equipped in weir notch amount water installations
Flow velocity measuring sensor is connect with controller respectively.
In said program, the inlet opening is elongated hole.
In said program, the water inlet hole surface is fixedly connected with filter screen.
The utility model has the beneficial effects that：The ultrasonic open channel flowmeter, using the triangle water blocking with inlet opening
Fluid is divided into two parts by cover cylinder, and most fluid passes through the flow velocity of acquisition fluid after flow rate of water flow measurement sensor, small portion
The fluid divided enters after triangle water retaining cover cylinder obtains water level by ultrasonic probe, and via controller obtains the stream of fluid after calculating
Amount.The device reasonable design, simple in structure, measurement is accurate.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other attached drawings.
Fig. 1 is the structural schematic diagram of ultrasonic open channel flowmeter in the utility model embodiment；
Number explanation is as follows in figure：1 weir notch amount water installations, 2 triangle water retaining cover cylinders, 21 inlet openings, 3 ultrasonic probes, 4
Controller, 5 flow rate of water flow measurement sensors.
Specific implementation mode
Keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings 1 and specific
Embodiment is described in further detail the utility model.
The ultrasonic open channel flowmeter that the present embodiment uses includes triangle water retaining cover cylinder 2 with inlet opening 21, ultrasound
Wave probe 3, flow rate of water flow measurement sensor 5 and controller 4.Triangle water retaining cover cylinder 2 is fixed on 1 bottom of weir notch amount water installations,
And the side of the triangle water retaining cover cylinder 2 where inlet opening 21 is located at flow downstream direction, inlet opening 21 and triangle water retaining cover
2 inner cavities of cylinder be connected to be formed detour into water loop, inlet opening 21 is elongated hole, and setting side by side is in triangle water retaining cover cylinder 2
Side wall on, ensure that fluid has stable flow velocity, can also be fixedly connected with filter screen in water inlet hole surface, prevent the dirt of bulky grain
Dye object enters in triangle water retaining cover cylinder 2, influences the accuracy of the height of water level in the weir notch amount water installations 1 detected.Three
The top of angular 2 inner wall of water retaining cover cylinder is fixedly connected with ultrasonic probe 3, and flow rate of water flow is equipped in weir notch amount water installations 1 and is surveyed
Quantity sensor 5, the ultrasonic probe 3, flow rate of water flow measurement sensor 5 are connect with controller 4 respectively.
The operation principle of ultrasonic open channel flowmeter in the present embodiment is：Most of fluid passes through weir notch amount water installations
When, the flow velocity of fluid is obtained by flow rate of water flow sensor measurement, and small portion of fluid enters triangle water retaining cover cylinder, due to three
Angular water retaining cover cylinder is identical as the water level of weir notch amount water installations, therefore can measure liquid level through ultrasonic probe, through control
Device calculates the flow for obtaining fluid.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
