  Types of   optical glass        As an older material, glass can be used not only in the fields of architecture and art, but also in medical treatment and instrumentation. Different types of glass have different characteristics and must be paid attention to when using them. However, most people don't know enough about glass, which often causes some misunderstandings and troubles. What are the different types of   optical glass 1. Colorless optical glass        There are specific requirements for optical constants, and it has the characteristics of high transmittance in the visible region and no selective absorption and coloring. According to the size of Abbe number, it is divided into coronal type and flint type glass, and each type is divided into several types according to the refractive index, and they are arranged in order according to the refractive index. Mostly used as lenses, prisms, and mirrors for telescopes, microscopes,...

  Precautions The correct selection of  Level Gauge  can ensure the better use of the level gauge. What kind of liquid level meter should be selected according to the physical and chemical properties of the measured fluid medium? The diameter, flow range, lining material, electrode material and output current of the liquid level meter can be adapted to the properties of the measured fluid And flow measurement requirements. Reflex Gauge Glass 1. Precision function check Accuracy level and function According to the measurement requirements and application occasions, select the instrument accuracy level to achieve economical and cost-effective. For example, for trade settlement, product transfer and energy measurement, you should choose a higher accuracy level, such as 1.0, 0.5, or higher; for process control, choose different accuracy levels according to control requirements; some only It is the occasion to check the process flow without precise control and measurement. You...

  1. Glass tube level gauge The glass tube liquid level gauge can have various forms according to the requirements of use. If the requirements are not high, it can be simple and self-made. The liquid level of the precision container can be a smoother and thicker glass tube (to reduce the capillary phenomenon) plus a more precise cursor Scale to read. A floating magnetic steel (also called float) is installed in the glass tube communicating with the container. Reed relays are installed on the upper and lower ends of the glass tube. As such, when the float is close to the thousand reed relay, the relay generates a switching action. The upper and lower limits of the liquid level can be controlled or alarmed.  Glass tube liquid level gauge is suitable for direct indication of lower pressure, open or sealed container liquid level. 2.Glass plate level gauge   Its structure is to open a thin groove on the thick tempered glass plate, the lower end is connected to the measured liq...

  1. Open the package, check that the installation is correct, and the level gauge is intact. 2. If there are multiple valves from the equipment to the liquid level gauge, first open the valves other than the liquid level gauge's own or closest to the liquid level gauge. 3. Slowly open the upper needle valve until it is fully open. 4. Slowly open the lower liquid needle valve until it is fully open. 5. Perform the flushing operation of the liquid level gauge, and eliminate the possibility of blocking the impulse pipe during the flushing. Note: When opening the valve and flushing operation, the valve should be opened slowly to prevent blockage caused by the action of the leak-proof device of the level gauge. How does the  glass plate level gauge  purge the oil stain on the inner wall? During the start of construction, the inner wall of the glass plate level gauge was stained with oil, which caused difficulties in observing the liquid level. The way to remove oil pollution ...
