[New patent introduction] An immersion liquid level gauge for measuring the liquid level of large fluctuating medium

Today, I will introduce a national invention authorized patent-an immersion level gauge for measuring the level of a fluctuating medium. The patent was applied for by Guofeng New Energy Jiangsu Co., Ltd., and the authorization was announced on March 27, 2018.

Content description

The invention relates to the field of liquid level measurement, in particular to an immersion liquid level gauge for measuring the liquid level of a large fluctuating medium.

Background of the invention

At present, the liquid level measurement of the fluid medium generally uses a radar ultrasonic level gauge or a radio frequency admittance level or a micro-pressure transmitter to measure the liquid level; the fluid medium in a power plant is generally water. If the water fluctuates greatly, the measurement The difficulty is great, and the accuracy of measurement will also be limited. In terms of economic performance, immersion level gauges are more economical. However, when the water flow fluctuates greatly and the disturbance cannot be eliminated, the probe of the level gauge will often be damaged due to the fluctuation, and the level gauge needs to be replaced, and the displayed water level is not accurate, and the operator cannot normally monitor the water level of the circulating water inlet.

Summary of the invention

In order to solve the above technical problems, the present invention provides an immersion liquid level gauge for measuring the liquid level of a fluctuating medium.

The technical scheme of the present invention is: an immersion type liquid level gauge for measuring the liquid level of a large fluctuating medium, comprising a measuring cylinder, a level gauge probe, a transmitter and a display; the measuring cylinder is a cylindrical structure with a closed bottom end and an opening at the top end , The wall of the measuring cylinder is provided with multiple through holes; the level gauge probe is arranged inside the measuring cylinder and located below the through hole, and is connected to the transmitter through a wire; the transmitter is connected to the display through a wire. The diameter of the measuring cylinder is 50mm and the length is 5000mm. The cylinder is made of seamless steel pipe, and the bottom end is blocked with a circular iron plate. The through holes are arranged in multiple rows, with multiple in each row, and the aperture is not limited. The bottom of the through hole array is left at a distance of 1/5 the height of the cylinder from the bottom surface of the measuring cylinder, and the total height of the through hole array occupies the total height of the cylinder. 2/5 of the height. The through holes are arranged in 3 columns. External protective cover for transmitter 5. The protective cover is made of plastic, iron sheet, stainless steel and other materials. The protective cover is set to a closed structure with a movable door, which facilitates the installation and replacement of the transmitter 3.

The present invention has the effect that the liquid level of the circulating pool is displayed normally through modification and installation, and accurate and reliable data is provided for the operating personnel; the immersion liquid level gauge does not appear to be damaged again and meets the design requirements. The installation of the measuring tube completely solves the problem of measuring large fluctuating media.

Entertainment Tablet

The advantage of entertainment tablet lies in having a powerful chip and excellent hardware. If you want to play various online videos on the tablet and run various software smoothly, the performance of the hardware is an absolute prerequisite. In addition, a high-speed and stable WIFI module is also required, which must be compatible with multiple 802.11 B/G/N protocols at the same time, so that the webpage can be loaded instantly when the webpage is opened, and the online video can be played smoothly. So hardware is the premise and foundation, without good performance everything else is empty talk.
In addition to having a good CPU as a prerequisite, it is equally important to carry a professional video player. A professional video player must perform equally well both online and offline.
