Description

1. Description

Locus Tubular Level Indicator Gauge is designed for continuous liquid level monitoring in tanks, vessels, and industrial equipment. The gauge consists of a high-quality borosilicate glass tube enclosed within a metal frame, ensuring durability and clear visibility. It is ideal for chemical, pharmaceutical, food processing, and water treatment industries.

2. Specification

Glass Tube: Borosilicate / Toughened Glass
End Connections: Flanged / Screwed / Welded
Sealing Material: PTFE / Neoprene / EPDM
Operating Pressure: Up to 10 Bar
Temperature Range: -40°C to 250°C
Standard Lengths: 300mm – 1500mm (Customizable)
Gauge Protection: Polycarbonate / Metal Shield
Mounting Type: Side / Front Mounted

3. Working

The gauge works based on the principle of hydrostatic pressure. The liquid inside the tank maintains the same level inside the glass tube due to the equalization of pressure. The operator can visually inspect the liquid level, ensuring accurate and real-time monitoring.

4. Principle

Communicating Vessels Principle: The level inside the glass tube matches the level inside the tank because of the open connection.
Pascal’s Law: The pressure at a given depth is the same in all directions, allowing the liquid level to remain stable.

5. Assembly

The Tubular Level Indicator Gauge consists of:

1. Glass Tube (Borosilicate)
2. End Fittings (Brass / Stainless Steel)
3. Valves (Drain and Vent)
4. Sealing Gaskets (PTFE / EPDM)
5. Protective Shield (Polycarbonate / Metal Casing)
6. Mounting Flanges / Screwed Ends

6. Installation Process

1. Prepare the Tank/Vessel: Ensure the surface is clean and suitable for mounting.
2. Fix the Mounting Brackets: Attach the gauge using the appropriate connection type (Flanged/Screwed).
3. Align the Gauge Properly: Ensure it is vertical and positioned correctly for maximum visibility.
4. Seal with PTFE Tape/Gaskets: Prevent leakage by sealing joints properly.
5. Connect the Valves: Attach the vent and drain valves to allow easy maintenance.
6. Check for Leakage: Perform a pressure test before use.
