Utility model content
The Ultrasonic water meter that technical problem to be solved in the utility model is to provide without the need to installing straight length before and after Ultrasonic water meter measures pipeline section, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Ultrasonic water meter is with measuring pipeline section, comprise straight length, be positioned at converter mount pad above straight length, be connected to the sensor mounting hole of straight length both sides in pairs, be communicated with sensor mounting hole and converter mount pad through wires hole and be connected the import undergauge at described straight length two ends respectively and export undergauge, it is characterized in that: the 55-65% that described import undergauge and described outlet undergauge are the undergauge of circular curve, osculum bore is large mouth bore, the aperture of described sensor mounting hole is 8-12mm.
The inwall of described import undergauge is also connected with the water conservancy diversion rib that structure is in the form of sheets dispersed.Described water conservancy diversion rib is the inwall being removably mounted on described import undergauge.
In the utility model preferred implementation, described osculum bore is 60% of described large mouth bore, and the aperture of described sensor mounting hole is 10mm.
Described straight length, described import undergauge, described outlet undergauge, described sensor mounting hole, described converter mount pad and described through wires hole are structure as a whole.
Described water conservancy diversion rib is six, is evenly distributed in the inwall of described import undergauge.
Described water conservancy diversion rib is connected and fixed by annulus, is placed in described import undergauge.
Adopt technique scheme, utility model, by by import undergauge and outlet undergauge is all designed to the undergauge of circular curve, osculum bore is designed to large mouth bore 55-65%, improves rectification effect; The aperture design of sensor mounting hole is 8-12mm, the impact of gauge hole stream field is dropped to minimum, thus makes whole pipeline section closer to the perfect condition in measuring, thus can be implemented in before and after Ultrasonic water meter and save connection straight length.
The water conservancy diversion rib that schistose texture is dispersed is added in import undergauge, at undergauge on the basis of high flow rate fluid rectification, rectification can also be carried out to low flow velocity fluid, the error that fluid instability produces can be effectively reduced, the measuring accuracy of flowmeter is further enhanced.
Therefore, the utility model has the advantage improving rectification effect, can be implemented in before and after Ultrasonic water meter and saves connection straight length, thus is conducive to Ultrasonic water meter replacement mechanical water meter.
