Description

Technical Field

[0001] This utility model relates to the field of water metering technology, and in particular to a box-type flow meter assembled from aluminum alloy profiles in a modular fashion. Background Technology

[0002] Ultrasonic box-type open channel flow meters can measure fluid velocity and level parameters, and calculate instantaneous flow rate by integrating velocity and level data. This product operates on the time-of-flight method, using an ultrasonic transducer to send ultrasonic signals in both the forward and reverse flow directions. The transducer receives the ultrasonic signals, obtaining time-of-flight information, and the integrator calculates the flow velocity. In ultrasonic level gauges, the transducer emits high-frequency ultrasonic pulses, which are reflected from the surface of the measured medium. The reflected echoes are received by the transducer and converted into electrical signals. Ultrasonic pulses propagate at the speed of sound, and the time interval from emission to reception is proportional to the distance between the transducer and the surface of the measured medium.

[0003] Existing box-type flow meters typically have a welded casing, which makes it difficult to replace individual damaged parts, leading to inconvenience in maintenance. To address these issues, the inventors have developed a box-type flow meter using modular assembly of aluminum alloy profiles. This new design utilizes aluminum alloy profiles for the casing, allowing for movable assembly rather than welding. This enables individual replacement of damaged parts, reducing maintenance complexity. A prototype of this product has been manufactured and is performing as expected. Utility Model Content
