How Ultrasonic Water Meter Work

Ultrasonic water meters calculate water flow by detecting the time difference when ultrasonic sound beams propagate downstream and upstream in water. Its core component is an ultrasonic transducer, which includes a transmitter and a receiver. When ultrasonic waves propagate along the direction of water flow, the propagation speed increases; conversely, when they propagate against the direction of water flow, the propagation speed slows down. By comparing the ultrasonic propagation time downstream and upstream, the speed of the water flow can be calculated. Based on this speed, combined with the cross-sectional area of the pipe, the flow value can be obtained.

 

Specifically, the ultrasonic beam emitted by one probe enters the pipe through the pipe wall, is reflected by the other side of the pipe wall, and is received by another ultrasonic probe. The path of the ultrasonic wave is V-shaped. During measurement, the upstream and downstream ultrasonic sensors take turns to transmit and receive ultrasonic pulses, and a high-precision digital timer is used to measure the time difference of the ultrasonic beam propagating in the pipe along the forward and reverse directions, respectively. The absolute value is ΔT. Assume that the inner diameter of the pipe is D, the angle between the ultrasonic beam in the pipe and the cross section of the pipe is θ, and the time from the emission to the reception of the ultrasonic wave when the fluid in the pipe is stationary is T₀. By measuring the above physical quantities, the fluid flow rate can be calculated.

Application of Ultrasonic Water Meter

Agricultural irrigation

The installation environment of agricultural water meters is generally harsh, while the waterproof grade of ultrasonic water meters is IP68, which can greatly reduce the frequency of water meter failures. This type of water meter has no mechanical transmission parts and no flow-blocking elements. The measurement is almost unaffected by water quality and can adapt to the conditions of poor agricultural irrigation water quality.

Smart City

Ultrasonic water meters have no pressure loss, effectively reducing the energy consumption of the pump and achieving energy-saving goals. Complete communication interfaces facilitate networking and remote monitoring, reflecting intelligence. Battery-powered, no mechanical transmission parts, long service life, and it plays an irreplaceable role in the construction of smart cities.

Urban and rural water supply

Ultrasonic water meters can adapt to various water quality conditions. The communication network is convenient, the output signal is multiple, and it is convenient for automatic settlement and computer management so as to realize the centralized management of water resources, improve management efficiency, enable remote monitoring, and reduce management costs.

FAQ

Q: What are the different types of ultrasonic water meters?

A: Ultrasonic flow meters are inferential meters that use ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter technologies, including Doppler and transit time.

Q: What is the basic principle of ultrasonic?

A: Driven by the pulser, the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propgates through the materials in the form of waves. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected.

Q: What is the difference between mechanical and ultrasonic water meter?

A: Ultrasonic meters are consistent over all flow ranges in the range the size covers. Low Flow - Ultrasonic meters are superior to mechanical meters at measuring low flow rates. One reason for this is that a mechanical meter has some start up friction. A piston, disc, or turbine rotor requires some force to start.

Q: How do ultrasonic water meters work?

A: In the case of ultrasonic flow meters, the frequency of an ultrasonic signal changes (Doppler Effect) in direct proportion to the rate of flow of the liquid when reflected by suspended particles or gas bubbles (discontinuities) in motion.

Q: What is the frequency of ultrasonic water meter?

A: The working frequency used by ultrasonic flowmeters is usually between 1MHz and 5MHz, of which 2MHz is the most common frequency. Different flowmeter manufacturers may choose different frequencies, depending on their technology and product design.
