Quartz Glass Tube Level Gauge
Quartz Glass Tube Level Gauge
The HQSYG quartz tube level gauge is developed using the latest high-tech advancements from both domestic and international sources. It is a replacement product for ordinary glass plate level gauges and is widely used in various transparent liquid containers and boilers in industries such as petroleum, chemical, power, and metallurgy. It is suitable for measuring the liquid level of various liquids and chemical raw materials such as water, gasoline, liquefied petroleum gas, liquid ammonia, propane, propylene, aromatics, and acids. It is also suitable for measuring the interface between two different media with different densities.
The HQSYG series quartz tube level gauge is developed using the latest high-tech advancements from both domestic and international sources. It is a replacement product for ordinary glass plate level gauges and is widely used in various transparent liquid containers and boilers in industries such as petroleum, chemical, power, and metallurgy. It is suitable for measuring the liquid level of various liquids and chemical raw materials such as water, gasoline, liquefied petroleum gas, liquid ammonia, propane, propylene, aromatics, and acids. It is also suitable for interface measurement of two different media densities. The colored liquid level gauge is installed on various containers and boilers, allowing for direct observation of liquid level changes. The liquid phase is displayed in green, the gas phase in red, and the interface measurement shows a three-color interface. The contrast between the liquid and gas phases is very high, making it clear and easy to see from a distance and during nighttime inspections. It successfully overcomes the shortcomings of ordinary plate-type level gauges, such as being bulky, having a large sealing area, being prone to leakage, and having unclear displays that are difficult to read from a distance.

Color liquid level gauge
|
UNS-A
|
The level gauge has valves at both ends, and these valves are equipped with safety devices. This prevents the container's contents from leaking out in case of accidental breakage of the quartz tube. Due to the small diameter of the valve passages, this type of level gauge is only suitable for measuring low-viscosity fluids.

Color liquid level gauge
|
UNS-B
|
It uses three-way flange connections at both ends and has no safety device. Due to its 20mm diameter, it can measure the liquid level of relatively viscous media.
|
|
|
Blind-spot-free color liquid level gauge
|
UNS-C
|
The connection at both ends uses a three-way fitting, and there are no safety devices. Due to the 20mm diameter, it can measure the liquid level of relatively viscous media; the measuring range is equivalent to the display height.
