Conventional Ultrasonic Sounder Working Principle
Ultrasound Sounder Working Principle The working principle of the ultrasonic depth sounder is designed based on the principle that the ultrasonic energy is transmitted in a uniform medium in a uniform medium and reflected in different media surfaces. The ultrasonic depth sounder uses the water body as the ultrasonic medium, and places the ultrasonic transducer at a certain position in the underwater when the depth is measured. The depth of the transducer to the bottom of the water can be transmitted according to the speed of the ultrasonic wave in the water and the ultrasonic signal is transmitted to the receiver. The time interval is calculated. Performance requirements 1, resolution Resolving power: 1 cm, 2cm, 5cm in different water depth detection ranges. 2, water depth detection range Water depth detection range: points (0 ~ 20) m, (0 ~ 50) m, (0 ~ 100) m third gear. 3, blind area Blind area: corresponding to 0.5m, 1.0m, and 1.5m in different water depth detection ranges. 4, measurement error Within the scope of measurement, the results measured at normal temperature and fixed reflection target shall prevail: a) When the water depth is less than 5m, the measurement error should not exceed ± 0.05m; b) When the water depth is greater than 5m, the measurement error should not exceed ± 1%. Other properties should meet the requirements of SL/T185-1997. 5, repeatability The repeatability error should not be greater than 0.5 times the sounder's measurement error. 6, reproducibility The reproducibility error should not be greater than 1.5 times the sounder's measurement error.

As we know,Tea is a traditional culture in China,we have many tools for making tea.There are some teas that go through many processes,one of the processes is filtering.But sometimes we wanna drink tea when we go travel or go outside,but we don't have any tools,how we can solve this problem?
How about take a silicone tea strainer? It's Food Grade material,you don't worry about its security.
