Handheld ultrasonic water depth meter product introduction:
The hand-held ultrasonic water depth meter is a portable sounder that measures water bodies such as reservoirs, lakes, rivers, shallow seas, etc. When the sounding is performed, the ultrasonic transducer is placed on the water surface or at a certain position, and the fixed sound velocity VC and ultrasonic waves in the water are transmitted to the receiving. At time T, the instrument automatically converts the water depth H. This product is a hand-held ultrasonic distance measuring instrument developed by our company with many years of production experience and taking advantage of many similar products. The ultrasonic transceiving and converting circuit adopts a dedicated large-scale integrated circuit, the component placement rate is 99%, and the liquid crystal display sounding result ensures the long-term reliability of the product, and at the same time reduces its power consumption to an extremely low level. Optional signal output makes up for the lack of products for traditional handheld products without output. The utility model has the advantages of accurate measurement, low power consumption, high reliability, convenient use, simple operation, accurate measurement speed and convenient carrying. The instrument can measure the depth in still water, or measure the depth in water with a certain speed; the water flow speed can reach 5m/sec. It is an ideal depth measurement for hydrological tests, hydropower plants, reservoir areas, lakes, river surveys and environmental waters monitoring. instrument.

The copying table is also called the writing table and the light-transmitting table. It is currently the most used in animation and comics and is an essential tool.When using it, you can overlap multiple drawings together, and you can clearly see the patterns on the bottom drawing. Using this function, you can easily copy the bottom drawing on the top paper. Therefore, many beginners of painting I will use a copy table to copy my favorite works.
