Glass tube liquid level gauge is a direct-reading measuring instrument designed according to the connecting device principle. It is widely used to measure the liquid level of various tanks, towers, tanks, boxes and other containers.
PP anti-corrosion glass tube level indicator has reliable and excellent corrosion resistance can be used to transport high temperature of strong corrosive gas, liquid. It has simple structure, small volume, light weight and convenient operation. Widely used in machinery, chemical industry, aviation, metallurgy, petroleum, pharmaceutical, food, environmental protection, health care and electrical insulation and other fields.
Product Features
- Simple installation and maintenance.

Why use glass level gauge
Glass level gauges have been in use for over 100 years. They give you the ability to directly view the process fluid under temperature/pressure conditions that would render most other level technologies useless.Their construction is very robust, and reliable. They define the term “simple to use”. After installation, the only tool you will need is your eyes. Glass level gauges are relatively inexpensive as compared to most other level technologies.
Please provide the following parameters when ordering:
- Model specification;
- The name of the medium to be measured, such as: water, petrol, paraffin, etc..
- Material requirements: e.g. SS304, 316L, carbon steel,PP, PVC;
- Connection: flange or thread;
- Flange standard: nominal diameter of the flange, currently used more DN20 or DN25 flange;
- Measuring range of the instrument: the centre distance of two flanges;
- Material of glass tube, diameter, length, wall thickness;
- Working pressure: the highest withstand pressure;
- Working temperature: minimum and maximum temperature of the measuring liquid;
- Special requirements: please explain in detail before ordering, such as whether to take the remote transmission, thermal insulation jacket and so on.
