Water Level Ruler Scale Generator
The water level scale scale generator is an electronic digital display scale scale equipment professionally matched by Tieling Tianguang Instrument and Meter Co., Ltd. for various water (liquid) level meter monitoring systems. It is a new product developed by using video overlay technology.
Nowadays, the commonly used industrial TV monitoring device for drum water level directly displays the video image of the boiler local water level gauge shot by the camera on the display screen of the monitor. However, due to the influence of on-site light and environment, this detection method can only see the liquid column image of the drum water level gauge on the industrial TV display screen, but cannot see the scale of the water level gauge clearly.
The TGSW-1P type water level scale generator completely solves this problem that has plagued water level gauge users for a long time. It can produce digital image signal corresponding to the scale scale, and superimpose it on the input water level image signal and then output to the monitor. The water level image with digital and scale image information superimposed will be displayed on the monitor, and the monitoring personnel can truly, intuitively and quantitatively observe the height of the drum water level. This instrument can display double-sided scales and mark the liquid level height of drum water level gauges on both sides (as shown in Fig. 1 on the right). And the instrument has the function of generating ruler width, horizontal position and ruler brightness adjustment, so that the generated digital ruler scale can adapt to different actual field environment and achieve the best observation effect.
The instrument is installed at the monitor end, far away from the measurement site, and the components are not affected by the on-site drum water, steam and high temperature environment. Long-term operation is safe, stable and reliable.
Based on the above characteristics, the scale scale generator has a wide range of applications:
Suitable for all kinds of monochrome, two-color water level gauge
In addition to the drum water level gauge, it is also applicable to the ruler superposition of the monitoring image of the water (liquid) level gauge for other purposes.
Working principle
The ruler scale generator adopts the video superposition technology, the digital scale signal is directly superimposed on the video signal input from the camera after editing by the digital logic chip, and then the video image driver chip outputs the superimposed video image.
