Product Overview
The Side Mounted Tubular Level Indicator is a simple, reliable instrument designed for direct visual observation of liquid levels in atmospheric and pressurized tanks. Mounted parallel to the tank wall, it provides a clear local indication as the liquid level changes inside the vessel.
Working Principle
As the liquid level rises or falls inside the tank, the liquid level inside the transparent glass tube changes correspondingly. The glass tube is enclosed within a protective housing fitted with a graduated scale, allowing easy and accurate level reading.
Key Features
Direct visual liquid level indication
Suitable for pressurized and atmospheric tanks
Rugged and simple construction
Clear graduated scale for easy reading
Low maintenance and long service life

Product Overview
A highly reliable and accurate system for liquid level measurement in underground and overhead storage tanks, especially suitable for large storage capacities.
Working Principle
As the liquid level increases, the float moves upward. This movement is transmitted through a wire rope running over low-friction nylon rollers, moving a pointer along a graduated scale for precise level indication.
Suitable For
Underground and overhead storage tanks
Water and DM water tanks
Petroleum products (oil, diesel, lube oil)
Vegetable oils, molasses, silicates, glucose
Non-hazardous, non-pressurized tanks

Product Overview
Glass Tube Variable Area Flowmeters are economical and reliable instruments used for measuring transparent fluid flow. Designed to withstand high pressure, corrosive fluids, and elevated temperatures without electronic interference.
Principle of Operation
As fluid flows through the tapered glass tube, the float rises until equilibrium is achieved between buoyant force and float weight. Flow is measured at the float’s stabilized position.
