The invention discloses a stainless-steel ultrasonic water meter, and relates to the field of water meters. The stainless-steel ultrasonic water meter aims at solving the problem that multiple defects exist in a mechanical water meter used by an existing inhabitant. According to the stainless-steel ultrasonic water meter, the ultrasonic
time difference principle is adopted, a full-electronic water meter made by industrial-grade electronic components is adopted, and compared with a mechanical water meter, the full-electronic water meter has the advantages that accuracy is high, reliability is good, the range ratio is wide, the service life is long, no moving part exists, parameters do not need to be set, and installing is carried out at any angle. On the basis of the
metering mode of the ultrasonic water meter, the
wireless collecting and reading characteristic and the valve control characteristic are also added. A pair of ultrasonic transducers are applied to receiving and sending ultrasonic
waves at a flow measurement part in the opposite directions, the flow velocity of fluid is indirectly measured by observing the
propagation time difference of downstream and upstream of the ultrasonic
waves in a medium, and then the flow is calculated through the flow velocity. The stainless-steel ultrasonic water meter is high in measuring accuracy, convenient to use and prone to digital management; compared with water meters made of existing materials, the
water quality is guaranteed; the stainless-steel ultrasonic water meter is suitable for measuring the water yield of a
tap water pipe.
