Description

Technical Field

[0001] The utility model belongs to the technical field of measuring instruments, in particular to an anti-scaling ultrasonic water meter structure. Background Art

[0002] Ultrasonic water meter is a new type of water meter that uses the ultrasonic time difference principle to measure water flow. Water meter is an instrument for measuring water flow, mostly the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. Currently, water meters mainly consist of a shell, a sleeve, and an inner core. The shell is generally made of cast iron as raw material.

[0003] Ultrasonic water meters detect the changes in the speed of ultrasonic sound beams when they propagate downstream and upstream in water, analyze and process these time differences to calculate the water flow rate, and thus derive the water flow rate. The water meter shell is a closed design, and the impurities deposited at the bottom of the shell cannot be cleaned, affecting the water flow rate and reducing the accuracy of the water meter. Therefore, we propose an anti-scaling ultrasonic water meter structure. Utility Model Content

[0004] The utility model aims to provide an anti-scaling ultrasonic water meter structure, by setting an auxiliary buckle, specifically, the staff adapts the adapting groove and the limit block to each other through the auxiliary buckle, and then the staff adapts the sealing cover to the disassembly groove through screws, so that the support block is in contact with the auxiliary buckle, thereby fixing the filter cartridge inside the filter box, and then when the water from the left water inlet pipe can accurately pass through the filter cartridge and be released from the right water outlet pipe, the function of filtering water is achieved, thereby making the ultrasonic water meter more accurate in detection, and solving the problem that the existing ultrasonic water meter detects the speed change of the ultrasonic sound beam when it propagates downstream and upstream in the water, analyzes and processes these time differences to calculate the water flow rate, thereby obtaining the water flow rate, and the water meter shell is of closed design, and the impurities precipitated at the bottom of the shell cannot be cleaned, which affects the water flow rate and reduces the accuracy of the water meter.
