Abstract
The utility model discloses a kind of new dovetail flowmeter in measuring equipment field, to solve to cause ultrasonic level gage to be unable to accurate measurement liquid level in measurement zone liquid level injustice at present, water consumption measurement the problem of deviation is occurred.It includes guiding gutter, measurement zone, the effluent trough being sequentially connected with, and ultrasonic level gage is equipped with above measurement zone, 12 pieces of porous water sieve plates are equipped with guiding gutter cross section.When current pass through the utility model, effectively buffered by porous water sieve plate in guiding gutter, water speed tends to be steady, prevent because flow velocity is uneven above and below water body, water surface liquid level irregular fluctuation causes liquid level skewness, so as to ensure that the accurate metering of the measurement effect of ultrasonic level gage and dovetail flowmeter.
Description
Technical field
It the utility model is related to a kind of new dovetail flowmeter in measuring equipment field.
Background technology
Dovetail flowmeter is the visual plant in water treatment procedure, and its main function is that inlet and outlet water is accurately surveyed
Amount.During measurement, current enter guiding gutter from import, flow through measurement zone, are discharged from effluent trough.Because water-carrying capacity is proportional to water surface height
Degree, after measuring water surface elevation by supersonic liquid level, you can calculate water flow value.Come from scene operation and its measuring principle
See, the fluctuation of the water surface directly affects the accuracy of metering.Because dovetail flowmeter is in continuous running, current pass through water conservancy diversion
During groove, with the reduction of discharge area, there is high " crest " phenomenon in the low centre in both sides in the water surface, causes in measurement zone ultrasonic solution
Position meter is unable to accurate measurement liquid level, water consumption measurement deviation is occurred.
Utility model content
The purpose of this utility model is to overcome prior art defect, there is provided a kind of new dovetail flowmeter.
What the technical solution of the utility model was realized in：A kind of new dovetail flowmeter, including what is be sequentially connected with are led
Chute, measurement zone, effluent trough, ultrasonic level gage is equipped with above measurement zone, it is, equipped with more on guiding gutter cross section
Hole water sieve plate.
Further, the porous water sieve plate installs 1-2 blocks along water (flow) direction.
Further, the porous water sieve plate has one piece to be arranged on the cross section that guiding gutter is connected with measurement zone.
When current pass through the utility model, effectively buffered by porous water sieve plate in guiding gutter, water speed tends to
Steadily, prevent that water surface liquid level irregular fluctuation causes liquid level skewness, so as to ensure because flow velocity is uneven above and below water body
The accurate metering of the measurement effect and dovetail flowmeter of ultrasonic level gage.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure top view.
In figure, 1- guiding gutters；2- measurement zones；3- effluent troughs；4- ultrasonic level gages；The porous water sieve plates of 5-.
Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, a kind of new dovetail flowmeter, including guiding gutter 1, measurement zone 2, the effluent trough 3 being sequentially connected with,
Ultrasonic level gage 4 is equipped with above measurement zone 3, hole sizer more than one piece is equipped with the cross section that guiding gutter 1 is connected with measurement zone 2
Water plate 5, one piece of porous water sieve plate 5 can be also installed in the proparea of guiding gutter 1 as needed again, form level 2 buffering so that be measured
The water surface tends towards stability, and " crest " disappears, and flows through measurement zone, is accurately measured by ultrasonic level gage 4, finally from the row of effluent trough 3
Go out, substantially increase the adaptability and accuracy of dovetail flowmeter.Porous water sieve plate 5 certain thickness steel plate or plastic plate system
Make, sieve aperture quantity and size specifically determine according to water velocity and discharge area.
