The water meter is a foreign name water meter and is a meter for measuring water flow. At present, most of water meters used in timing charging systems for centralized water supply in civil houses and office buildings are ultrasonic water meters, and the ultrasonic water meters are novel water meters for further calculating the flow of water by detecting time differences generated by speed changes when ultrasonic sound beams are propagated in concurrent flow and counter flow in water and analyzing and processing the flow rate of the water. The high-quality low-voltage ceramic transducer is adopted in the meter, so that high accuracy and stability are guaranteed. The meter has no mechanical movement, no abrasion, no influence of bad water quality and low maintenance cost. The watch can be horizontally and vertically installed, and the humanized design meets the requirement of normal reading visual angles, so that the reading is more convenient.
