Glass Tube Level Gauge for Accurate Visual Level Measurement
A glass tube level gauge is a simple and reliable visual level indication device used to directly observe liquid levels in tanks, vessels, and industrial systems. By using a transparent glass tube connected to the process vessel, operators can clearly monitor real-time liquid levels without complex instrumentation.
We provide glass tube level gauges designed for stable performance, easy installation, and clear visibility in a wide range of industrial applications.

What pressure range can the INGT114 glass tube level gauge support?
The INGT114 glass tube level gauge supports nominal pressures from PN6 to PN100. For configurations with 304 stainless steel and PTFE lining, the maximum nominal pressure is PN40.
Can the INGT114 glass tube level gauge be customized for different center distances?
Yes. The INGT114 glass tube level gauge is available with standard center-to-center distances ranging from 300 mm to 2000 mm, and custom lengths can be manufactured based on installation requirements.
Is the bi-color indication suitable for all applications?
The bi-color indication of the INGT114 glass tube level gauge is suitable for applications where clear phase differentiation is required. Red indicates the vapor phase, while green indicates the liquid phase, improving visibility during operation.
What materials are available for corrosive media?
For corrosive process media, the INGT114 glass tube level gauge can be supplied with stainless steel materials such as 316L or with a 304 stainless steel body featuring a PTFE lining to improve corrosion resistance.
Does the INGT114 glass tube level gauge require electric heating?
Electric heating is optional. The INGT114 can be equipped with self-limiting temperature electric heating when required, while anticorrosive configurations generally do not require additional heating.
What safety features are included in the INGT114 glass tube level gauge?
The INGT114 glass tube level gauge includes a steel ball self-closing mechanism that activates at pressures ≥ 0.3 MPa, helping to reduce liquid leakage in the event of glass tube damage.
