About us - Tank Calibration

Who Are We?

We are an independent private company headquartered in Kolkata, India, specializing in tank calibration, inspection, certification through various international governmental metrological departments and non-governmental organizations, ultrasonic testing, tank settlement, and tilt surveys.

The company was conceptualized in 1987 as a proprietorship firm by the late Tomojit Ghosh (1935–1995), a chemical engineer from Jadavpur University, Kolkata. He held a Master’s degree and possessed extensive expertise in metallurgy, inspection, and surveying.

Our Vision

Since then, we have expanded across geographical boundaries to extend our quality services to organizations of all sizes, big or small. No job is considered too small for us. We are motivated to continuously raise our standards in today’s competitive industrial environment.

Carrying forward this legacy and led from the forefront by Prosenjit Ghosh, AMIE, an engineer with 25 years of experience and a strong focus on technical and mathematical innovation, we are committed to providing not only volumetric accuracy but also complete survey solutions to our clients at competitive rates, both across India and internationally.

Our global footprint reflects our vision of developing TGC into a globally competitive and capable organization, backed by quality services, competitive pricing, and a strong professional team.

Our Edge

We are now a consortium of efficient, responsive, and experienced engineers with on-field technical expertise combined with CAD-modeled mathematical volume analysis. We certainly have the edge with continuous technological innovation and upgrades, meeting international standards such as Laser EODR, OTM, and laser-scanned tank bottom volumes, and solving other intricate problems, such as tilted underground tanks.

Our Focus

Our focus is to help tank owners understand the critical importance of accurate volume measurement. Tank calibration and surveying provide owners with a thorough understanding of their inventory, supporting accurate mixing, consistent product quality, and better monitoring of tank condition.

When tank measurements are performed incorrectly or left unchecked, they can lead to significant operational and financial consequences. Our thorough understanding of tank characteristics has earned us a reputation as a trusted solution provider in the industry, serving clients across India and internationally.
