There are two types of glass level gauges: translucent glass level gauges and reflective glass level gauges. According to the actual color classification, they can be divided into two-color glass level gauges and single-color glass level gauges. In addition, for high temperature or corrosive media, high-quality mica sheets can be used to prevent the medium from eroding the glass, so as to ensure the observation effect and the service life of the liquid level gauge. According to the difference of pressure and temperature resistance, it can be divided into medium and low pressure glass plate level gauge, high temperature and high pressure glass plate level gauge, frost-proof glass plate level gauge.
According to customer needs, it is designed to be without blind area. If customers need to directly read the liquid level height, the scale can also be added.
1. Self-closing design (standard):
In order to improve the safety performance of the glass level gauge, this product adopts a special structural design when designing the glass level gauge (valve). , automatically close the liquid flow channel to prevent the medium from continuing to flow out.
2. Heat tracing device (optional)
The heat tracing or cooling device can be customized according to the customer's measurement requirements. There are various types of connection ports, which can be customized according to the form or size of the customer's on-site interface, and there is no need for the customer to change the form or size. When heating, it can be heated by steam or hot water to prevent the medium from freezing or crystallizing when the temperature is too low. During cooling: when the temperature of the measuring medium is too high and gasification is likely to occur, cold water can be introduced for cooling to slow down the gasification of the medium and make the liquid level display more accurate and stable.
3. Red and green two-color display (optional)
The glass of the glass level gauge is made of high-quality high-pressure glass, which has the characteristics of uniform thickness, high transparency, clear indication, corrosion resistance, high temperature and high pressure resistance, etc. According to the customer's on-site use requirements, special technology and materials can be used, and the liquid level can be displayed in two colors by using the optical principle, making the liquid level display more clear and intuitive.
4. Display the scale ruler (optional)
This product can add a scale scale to the display body part of the glass level gauge according to the needs of customers, so that the glass level gauge can directly read the height of the liquid level scale like a magnetic flip level gauge, which greatly simplifies And facilitate the liquid level measurement process.
5. No blind area optimization design (optional)
In order to meet the measurement requirements of no blind zone, this product has optimized the design of the traditional basic glass plate level gauge. By moving the connecting pipe upwards, the measurement requirements of no blind zone are achieved.
