Household ultrasonic water meter is an innovative water meter used for household water metering.
1. Working principle
It uses the time difference or frequency difference generated when ultrasonic waves propagate in the water downstream and upstream to measure the water flow velocity. When water flows through the water meter, the ultrasonic sensor alternately transmits and receives ultrasonic signals. Since the flow of water will change the ultrasonic propagation time or frequency of the upstream and downstream, the built-in high-precision chip accurately calculates this change to obtain the speed of the water flow, and then combines it with the parameters such as the pipe diameter inside the water meter to accurately measure the water consumption.
2. Performance characteristics
High-precision measurement
Household ultrasonic water meter has high measurement accuracy and can accurately measure the tiny water consumption of the household, avoiding the measurement errors that may occur in traditional water meters, and ensuring the fairness and accuracy of user water measurement.
No mechanical wear
Unlike traditional mechanical water meters, ultrasonic water meters have no mechanical rotating parts, and there is no problem of mechanical wear caused by long-term use. This not only extends the service life of the water meter, but also reduces the risk of inaccurate measurement caused by mechanical failure.
Low starting flow rate
It has a low starting flow rate and can sensitively detect small water flows. Even if there is a very slow dripping phenomenon in the home, the ultrasonic water meter can accurately measure it, which helps the family save water and avoid waste of water resources.
Wide range ratio
It can achieve accurate measurement in a wide flow range, whether it is a small flow of daily household water use, such as a trickle when washing hands and brushing teeth, or a large flow of water use, such as a bath, The water flow when the washing machine is filled with a large amount of water can be accurately measured.
3. Advantages
Smart function
Many Household ultrasonic water meters have smart functions, such as being able to connect to the home smart home system to realize remote reading, water use data statistical analysis and other functions, which is convenient for users to understand the household water use situation at any time and arrange water use plans reasonably.
Environmental protection and energy saving
Its high-precision measurement helps families save water and contributes to the protection and conservation of water resources at the household level.
