Unparalleled Clarity and Reliability with the ISEN Glass Tube Level Gauge
The Glass Tube Level Gauge is a fundamental instrument for visual liquid level indication in tanks and boilers. The ISEN series offers a diverse selection of gauges, ensuring a perfect fit for various pressure, temperature, and corrosive environments
Featured ISEN Glass Tube Level Gauge Models
Valvelink offers several specialized ISEN models to meet specific industry needs:
ISEN-UGS-A (GZS-A) Bi-color Quartz Glass Tube Liquid Level Gauge
Designed for high-pressure and high-temperature applications, this model provides an exceptionally clear visual distinction between liquid and gas phases.
- Display: Utilizes a red and green glass sheet system where green indicates liquid and red indicates air. An optional electric light can be added to enhance visibility.
- Operating Range: Handles temperatures from -20°C up to 600°C and pressures up to 10MPa.
- Measurement Range: Available in lengths from 300mm to 3200mm.
- Materials: Constructed from durable carbon steel or SS304 stainless steel.
- High-Pressure Tube: Features a robust quartz glass tube with an outside diameter of 29mm and 10mm thickness, tested to a pressure of le13MPa.
ISEN-GZS-C Series Economic Glass Tube Water Level Gauge
For standard applications requiring reliability and cost-effectiveness, the GZS-C series is an ideal choice.
- Versatile Range: Measures ranges from 300mm up to 5000mm.
- Operating Conditions: Suitable for temperatures up to le180circC and pressures from 0 to 16 Bar.
- Material Options: Body can be made from carbon steel, SS304, or SS316.
- Safety and Protection: Features a needle valve with an internal safety ball check and a U-shaped aluminum housing to protect the transparent tube.
- Connection Flexibility: Can be ordered with any type of thread or flange connection.
ISEN-B49HT Double Color Quartz Glass Tube Water Level Indicator
This model is specifically engineered for boiler applications, incorporating critical safety features.
- Safety First: The gauge is equipped with upper and lower valves that house a safety steel ball. If the quartz glass tube breaks, high-pressure steam automatically pushes the steel ball to the valve seat, shutting off the channel until the valves can be manually closed. The ball resets automatically once pressure is equalized.
- Clear Bi-Color Display: Provides an unmistakable visual indication, showing green for the water level and red for air (steam). An LED light assembly can be included for constant, clear viewing.
- High-Performance Specifications:
- Working Temperature: −20circC to 450circC, with options for up to 600circC.
- Pressure Rating: Available for PN2.5, PN4.0, PN6.4, and PN10MPa systems.
- Materials: A105, SS304, or SS316.
- Connections: Standard DN25 flange, with other options available.
