​Industrial Level Indicators: Engineering Precision for Process Safety

​Flowtel Engineering manufactures high-end Level Indicators specifically designed for the visual monitoring of liquid and solid levels in tanks, pressure vessels, and industrial silos. Our instruments provide operators with an immediate and accurate assessment of material heights, enabling critical decision making and preventing operational overflows or dry-run conditions.

​Our indicators are engineered to outperform in harsh conditions, including high-temperature steam applications and aggressive chemical processing. At Flowtel Engineering, every device undergoes rigorous testing to ensure compliance with global safety standards and industrial regulations. Whether your project requires Magnetic, Reflex, or Tubular level gauges, we provide the durability and clarity essential for seamless integration into your facility. From water treatment systems to oil and gas refineries, our Level Indicators are built to deliver maintenance-free performance and long-term reliability.

Tubular Level Indicator

Tubular Level Indicator

Level Indicators

Tubular Level Indicator is used to visually check the liquid level inside tanks and vessels. It consists of a transparent glass tube connected to the tank, allowing the liquid level to be seen directly. As the liquid level in the tank rises or falls, the level inside the glass tube changes accordingly, making it easy to read against the scale. These indicators are simple in design, easy to install, and require minimal maintenance. Tubular level indicators are widely used in water tanks, chemical industries, and process plants for reliable and clear level indication.

Reflex Level Gauge

Reflex Level Gauge

Level Indicators

Reflex Level Gauge is used to visually indicate the liquid level inside tanks and vessels. It works on the principle of light reflection and refraction, where the liquid zone appears dark and the vapor or gas zone appears bright, making the level clearly visible. This type of level gauge does not require external lighting during the day and provides clear and reliable indication. It is simple in design, easy to install, and requires low maintenance. Reflex level gauges are widely used in process industries, boilers, and storage systems where quick and accurate level indication is required.

Transparent Level Gauge

Transparent Level Gauge

Level Indicators

Transparent Level Gauge is used to visually observe the liquid level inside tanks and vessels. It consists of two transparent glass plates between which the fluid flows, allowing clear level indication. In some applications like water or steam, external lighting is used to improve visibility. This type of level gauge is suitable for applications where liquid color or interface between two liquids needs to be observed. It can also be used with mica or PTFE shields to protect the glass from corrosive fluids. Transparent level gauges are widely used in process industries for accurate and clear level monitoring.

Float And Board Level Indicator

Float And Board Level Indicator

Level Indicators

Float and Board Level Indicator is used to measure and display the liquid level in storage tanks. It works on a simple buoyancy principle, where a float moves up and down with the liquid level and is connected to a pointer or board through a rope or tape mechanism. As the liquid level changes, the float movement is transmitted to the external board, showing the level clearly from a distance. This system is simple, reliable, and does not require any power supply. Float & board indicators are widely used in water tanks, overhead tanks, and storage vessels for continuous level indication.

Side Mounted Magnetic Level Gauge

Side Mounted Magnetic Level Gauge

Level Indicators

Side Mounted Magnetic Level Gauge (FEMLT-100) is used to indicate the liquid level in tanks and vessels under various operating conditions. It operates on the principle of magnetic coupling, where a float containing a permanent magnet moves with the liquid level inside a side-mounted chamber connected to the vessel. The float's magnetic field actuates an external indicator consisting of magnetic rollers or flaps that change color as the float rises or falls, providing a clear and continuous visual level indication. Since the process fluid remains completely enclosed within the chamber, the system offers leak-proof operation, enhanced safety, and minimal maintenance. Side mounted magnetic level gauges are widely used for hazardous, corrosive, high-pressure, and high-temperature liquids across various industrial applications.

Weld Pad Type Level Indicator

Weld Pad Type Level Indicator

Level Indicators

Flowtel Engineering Make Weld Pad Liquid Level gauge is designed to be welded directly onto a tank or other liquid-containing vessel, and allows visual observation of level, color, or clarity of a liquid in a vessel or tank at a low initial cost. Upon request, the unit can be machined with a cylindrical radius to match the contour of the vessel. The Liquid Level Gauges are available in single or multiple section types.

Top Mounted Magnetic Level Gauge

Top Mounted Magnetic Level Gauge

Level Indicators

Top Mounted Magnetic Level Gauge (FEMLT-200) is used to indicate the liquid level in tanks and vessels where top installation is preferred. It operates on the principle of magnetic coupling, where a float containing a permanent magnet moves vertically with the liquid level inside a guide pipe or chamber suspended from the top of the vessel. The float's magnetic field actuates an external indicator consisting of magnetic rollers or flaps that change color as the float rises or falls, providing a clear and continuous visual level indication. Since the process fluid remains completely enclosed within the guide pipe or chamber, the system offers leak-proof operation, enhanced safety, and minimal maintenance. Top mounted magnetic level gauges are widely used for hazardous, corrosive, high-pressure, and high-temperature liquids across various industrial applications.
