Description

Technical Field

[0001] The utility model relates to the technical field of water meter manufacturing, in particular to a centrosymmetric stamping ultrasonic meter case. Background Art

[0002] Ultrasonic water meter is a water meter that uses the ultrasonic wave propagation rate between transducers to calculate the water flow rate. It has the advantages of convenience and high accuracy and is widely used.

[0003] However, in current ultrasonic water meters, the ultrasonic wave transmitted between the two transducers will be received only after being reflected by the inner wall of the meter case several times, and the reflection will cause loss, which will reduce the accuracy of water flow calculation. Utility Model Content

[0004] The purpose of the utility model is to provide a centrosymmetric stamping ultrasonic watch case in order to overcome the defects of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A centrally symmetrical stamped ultrasonic watch case, the ultrasonic watch case comprising a straight tube-type watch case body; water inlet pipes and water outlet pipes are centrally symmetrically arranged on both sides of the watch case body; transducer bases for mounting transducers are symmetrically arranged at both ends of the watch case body; each of the transducer bases is fixed to a fixing hole on the watch case body by two screws; the watch case body is formed by welding a plurality of stamped parts, including an upper base plate, a lower base plate and two side plates.

[0007] Furthermore, the end of the water inlet pipe is provided with a circular water inlet; the end of the water outlet pipe is provided with a circular water outlet.

[0008] Furthermore, the ultrasonic watch case is made of stainless steel.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] (1) The transducer base of the utility model is at both ends of the case, so that the transducer directly transmits ultrasonic waves in a straight line inside the case, without reflection and loss of sound waves, thus improving the calculation accuracy of water flow. At the same time, the transducer spacing is longer, the signal time difference is longer, and the accuracy is also higher. There are no other parts inside the ultrasonic case, so when there are similar linear objects in the water, there will be no hanging threads, which will affect the sound wave collection.

[0011] (2) The ultrasonic meter case of the utility model is formed by stamping and welding of stainless steel plates, and has a simple structure, is easy to manufacture, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS
