Supplementary Information:

1. Structure and working principle
Flanges are added to meter with up and low valves. The flanges connect with tank and make a communicator with tank. Then the liquid level will be read from the Transparent glass tube or glass plate directly.

The upper and lower valves have steel balls inside. So if the glass plate or glass tube was broken by accident, the steel ball will block the channel under pressure, and to assure the container be sealed automatically which can prevent the liquid from flowing out.

Tubular Level Gauges are designed to view liquid levels using clear or red line Borosilicate (Pyrex) tubing. All valves use a stuffing box configuration to seal the glass tube, and have a ball check shutoff to prevent loss of vessel contents in case of glass failure. Operating pressure and temperatures are subject to the limitations of the tubular gauge glass and washer composition; consult with Pressure Products for gauge glass ratings.

The tubular level gauge is used for visual liquid level indication and is the most commonly used instrument in the process industry. It is a simple and reliable device for level reading in atmospheric or pressurized tank applications. It is mounted parallel, along the side of the tank, so as to form a closed loop. As the process level fluctuates, the level in the transparent glass tube changes accordingly and gives a local level indication.

2. Choice of Tie Rod or C-Frame Construction.
With or without isolating valve.
Material integrity assured through strict compliance of chemical composition analysis in a Standard Laboratory.
H Grade Borosilicate glass tube 16/19/25 mm outer dia with  Packing.
Glass tube can be removed online i.e. without disconnection from vessel
Standard Connection: 1/2" / 3/4" / 1" Flange drilled to ASA 150#, others on request
Alluminium/SS scale with 5 mm resolution as standard and 1 mm on request.
Drain Plug 1/2" Vent Plug 3/4" and drain/vent valve as optional
Safety Ball check device(optional).
Defrost/illuminator available on request.
Hydro test pressure: 12 KG/cm2, 100 Deg C max working temperature.
Tie Rod Construction is 'light' and permits 360ºC visibility.
C-Frame construction is robust and permits observation from Front & Rear.
Both constructions are available in integral or inline arrangements.
High quality, H grade borosilicate glass tube in 16/19/25mm outer dia is used.
Available in single length having c/c distance = 1600 mm. Extended lengths are provided by coupling several tubes or gauge assemblies in series.
Gland packing design provides tension-free tube installation to achieve zero leakage. It also enables glass removal for replacement or cleaning without dismantling the gauge or disconnection from the vessel.
Transparent Acrylic Plate mounted on C-Frame/Acrylic Pipe or slotted metallic pipe clamped on Tie Rod as glass protector can be provided if required, for additional safety to glass & personnel.
Adjustable proximity/reed switch arrangement for level sensing with alarm relays.
