A Tubular Level Gauge is a simple and cost-effective instrument used for direct visual indication of liquid level in atmospheric or low-pressure tanks. It consists of a transparent glass tube through which the liquid level inside the tank can be directly observed.

A Float and Board Level Gauge is a simple mechanical device used to visually indicate the level of liquid in a tank or vessel. It consists primarily of two main components:

• Float: A buoyant element that rests on the surface of the liquid inside the tank. As the liquid level rises or falls, the float moves correspondingly up or down.

• Board (Indicator Board): Attached externally to the tank, this board provides a visual reference scale, often marked with level graduations (e.g., in centimeters or liters). The float is connected to a pointer or a rod that moves along the board, showing the exact liquid level.

An IBR Reflex Level Gauge is a Reflex Type Liquid Level Gauge that complies with the Indian Boiler Regulations (IBR). These gauges are specifically designed and approved for boiler drum level indication and are widely used in power plants and steam boilers where compliance with safety regulations is mandatory.

A Reflex Level Gauge is a mechanical instrument used to visually monitor the level of liquid in a tank or vessel. It is known for its high visibility, reliability, and simplicity, and is commonly used in applications involving water, oil, steam, and various chemicals.

A Fuel Level Gauge is a precision instrument designed to provide accurate measurement and indication of fuel levels inside storage tanks, fuel reservoirs, or vehicle fuel systems. It enables real-time monitoring to prevent overflow, ensure optimal fuel management, and support safe operation.

The Reflex Flat Glass Level Gauge is a robust and highly visible liquid level indicator designed to provide clear, unambiguous measurement of fluid levels in tanks and vessels. It features a flat reflex glass window that enhances the visibility of the liquid level by using the principle of light refraction and reflection.

An SS Magnetic Level Gauge is a stainless steel-constructed instrument used for safe, reliable, and continuous visual level indication of liquids in pressurized, hazardous, or corrosive environments. It is based on magnetic coupling technology and is widely used in chemical, petrochemical, oil & gas, water treatment, and power industries.

“NRG GLOBAL INSTRUMENTS’ make Float & Board Level Indicators are designed for an accurate, reliable & trouble free float operated technique used in large non -pressurized storage tanks

Direct Indication

The Float & Board Level Indicators consists of a float connected to a pointer through a rope via a set of pulleys. The pointer glides over a calibrated gauge board, positioned parallel to the tank. The float accurately follows liquid level variations in vertical direction. The horizontal float movement is as such, the pointer in ‘TOP POSITION’ when tank is ‘EMPTY’ and in ‘BOTTOM POSITION’ when ‘FULL’.

Reflex liquid level gauge has a sturdily constructed body, with the glass and cover securely held by U-bolts to maintain a hermetic seal (see figure below). This type of level gauge features several parallel grooves cut into the glass surface that is in contact with the liquid. The resulting prismatic diffraction gases to appear white by reflection : liquids black by absorption thus the level of even transparent liquids can be clearly observed. Low-medium and high-pressure type may be used according to application conditions and units may be manufactured using carbon steel, stainless steel or a wide variety of other materials for parts in contact with the liquid. Type L100 reflex gauges have a number of further advantages including light weight, availability of long visible lengths and low price.

The Float and Board Type Level Indicator is a mechanical liquid level measurement device designed for reliable, continuous level indication in large storage tanks and process vessels. It operates using a buoyant float connected to a board or graduated scale, providing a straightforward visual representation of the liquid level.
