Glass Plate Type level Gauge is a common type level gauge, and the Glass plate include reflex gauge glass (Reflexion gauge glass) and  transparent gauge glass (plain gauge glass or flat gauge glass). It is very important to obey the right method of level gauge installation and maintain to protect the gauge glass part. a). Inspection method of glass plate Type level gauge 1. Remove the bolts and nuts on the glass plate level gauge, and remove the gland, gauge glass gasket, gauge glass and  mica shield  in order (only the level gauge for measuring alkaline medium  has mica shield, in order to protect transparent gauge glass, and other reflex gauge glass type level gauge don’t have mica shield). 2. Clean the dust and oil stains on the level gauge; 3. Remove the rust on the level gauge; 4. Remove the residue of the sealing gasket in the sealing window of the level gauge, taking care not to damage the sealing surface; 5. Trim the sealing surface to make the surface roughn...

Borosilicate glass mainly refers to toughened (tempered) borosilicate glass. It is a type of glass whose main components are SiO 2   and B 2 O 2 . It has high working temperature, considerable thermal shock resistance and excellent resistance to chemical attacks. Buy All Type  Gauge Glass  From Aohong Special Glass Manufacturing Co,.Ltd. Borosilicate glass has a very low coefficient of thermal expansion, which can withstand high thermal shock, and the glass surface changes very little with temperature. It is the first choice for precision instruments. Borosilicate sight glass contains few ferrous ions and has no obvious absorption in the visible spectral region, so it appears clear, transparent and colorless. It can be used as an observation window for effective and intuitive observation, so it is widely used. Borosilicate sight glass can be processed into flat (such as round, square, special-shaped) glass, and it can also be processed into tubular glass. The flat gl...

Despite its small size, a boiler’s sight glass has big importance. In this post we’ll cover how to replace an old or malfunctioning sight glass so you can keep your boilers working and your workplace safe.  It’s important to note that different types of glass and different lengths of glass will provide you with different readings. Always make sure that the glass you’re using is rated for your boiler. Now let’s get started! NO PRESSURE Check to make sure the shut-off valves are tightly closed, or make sure your boiler is completely empty of pressure and water. Be positive that there is no pressure in the line before replacing your sight glass, or you risk serious injury. In our sight glass replacement demonstration video, we use a boiler that is not firing or hooked in.  DOWN THE DRAIN Once you’re positive the line has no pressure, valve the water column off, and drain the water from the gauge through a valve at the bottom. Remove the protective rods, crack the nuts on the...

  As a   Fused Quartz Glass Supplier , share it with you. Quartz Glass After the instrument has been used for a period of time, it will appear to be dusty. The dust on the machine will cause a large error in the instrument, and it may also lead to a failure of the test. Therefore, the instrument must be clean and punctual in the process of use, so as to ensure the normal use of the instrument. Today, I will introduce us to the cleaning methods of quartz glass instruments and meters, and hope that these cleaning methods can help us. Quartz glass instrumentation Quartz glass instrumentation cleaning. Never use strong alkali to clean, because strong alkali will corrode the polished cuvette. It can only be soaked in lotion or 1% to 2% detergent, and then rinsed with tap water. At this time, use a small stick or cotton swab wrapped in silk cloth to rinse. The effect will be very good. Clean and clean the cuvette No water droplets hang on the inner and outer walls. The glass and pla...

As a   Glass Lab Manufacturer , share with you. Coating is to coat a very thin transparent film on the surface to reduce light emission. There are many production methods for coated glass, mainly including vacuum magnetron sputtering method, vacuum evaporation method, chemical vapor deposition method and sol-gel method. Optical Glass Blanks 1. Magnetron sputtering coated glass can design and manufacture multi-layer complex film system by using magnetron sputtering technology, which can plate a variety of colors on the white glass substrate. The film has good corrosion resistance and wear resistance, which is suitable for production. And one of the more used products. 2. There is a certain gap between the variety and quality of vacuum evaporation coated glass and magnetron sputtering coated glass, which has been gradually replaced by vacuum sputtering. 3. The chemical vapor deposition method is to introduce reaction gas into the float glass production line to decompose on the hot gl...

  As a   Level Gauge Glass Manufacturer , I would like to share with you. Routine inspection of level gauge and troubleshooting methods, suitable for magnetic flap level gauge, two-color quartz tube level gauge, glass tube level gauge, etc. 1. First check whether the power supply is connected correctly. If the connection method is found to be incorrect, modify it according to the operation manual. 2. Use a three-voltmeter to measure the voltage between +24V and O/P. The voltage should be between 13V and 36V. If the voltage is abnormal, check whether the circuit or related equipment is abnormal. 3. The second item should be confirmed to be normal, and then a milliamp meter should be connected to the 4~20MA circuit to check whether the current is normal. If the current value is abnormal, replace it with a new product or contact customer service personnel. Transparent Level Gauge 4. Use a voltmeter to check the voltage between IN and COM. Normally, it should be about 2.5V. If the...

As a   Level Gauge Glass Manufacturer , share with you. There are two types of glass level gauges: reflective and transparent. Reflective liquid level gauges are widely used in liquid level measurement in specific containers. The principle is based on the different reflectivities of steam and liquid. Reflective liquid level gauge is also called square level gauge, it provides clear water level picture boundaries. This reduces the risk of distortion or reading area. For this reason, the reflective level gauge can be installed at a squint angle or a vertical position, and can even provide higher reading accuracy and better reliability. As you can imagine, this will greatly benefit many industries. Reflex Level Gauge The reflection type liquid level gauge detects the difference in reflectivity between steam and liquid, and has flexibility. Multiple liquid level gauge sections can be combined to expand the observation area. The reflection type liquid level gauge is also extremely flexi...

  AOHONG   Glass supplies   Gauge Glass   from top manufacturers , which used in   pharmaceutical , laboratory, industrial and electronics industries, because of the feature of   gauge glass , such as high working pressure, high working temperature, corrosion resistance, clear liquid level, no contamination to liquid and friendly to environment In boiler , the sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within. Gauge glass  provides you with a way to view the level of liquid or gas passing through design key points, monitor pressure changes, and almost all other things you can do with the sight glass window When steam is slowly flowing out of the pipe, keep the ammonia cup at the end of the discharge line to allow the steam to bubble upward through the ammonia. Close the top pressure gauge valve, which will cause the steam to quickly co...

  As a   Sight Glass Tube Supplier , share with you. Using a sight glass is probably the easiest way to measure the liquid level. The observation mirror is installed outside the water tank, so the liquid level can be observed through the glass. The sight glass is marked with a scale to measure the liquid level. The main disadvantage of this method is that it only gives a partial indication of the liquid level of the container. When a part of the container is made of transparent material or the liquid in the container is bypassed through a transparent tube, a visual indication of the liquid level can be obtained. The advantage of using a shut-off valve with a bypass pipe is that it is easy to disassemble for cleaning. Sight Glass Type Level Gauge Type of level gauge: Transparent Level Gauge The transparent level gauge uses two pieces of transparent glass, both sides are equipped with liquid chambers. The indicated liquid level is the result of the different transparency of the ...
