Our Lean Journey- Continuously Improving….
Pursuit Of Calm And Efficiency From
At IOTAFLOW, we prioritize efficiency and
State Of Chaos And Fighting Fires
continuous improvement in our operations. A
quest to avoid firefighting with timely delivery
and quality of the products lead us to discover
2SL. Our commitment to lean principles began
in October 2021. Since then our implementation
efforts encompass comprehensive training
programs on reducing 8 wastes, implementation
of the 2 Second Lean philosophy, utilization of
Kanban Cards for inventory control, adoption
of the Supermarket Concept, and implementation
of the One-Piece Flow methodology.

The positive outcomes of our lean journey

extend beyond achieving quality and on-time
delivery. Our operations now boast a seamless
process flow, ensuring optimal efficiency and
productivity throughout our organization. We
have witnessed a more enjoyable work
environment, demonstrating that embracing
lean practices brings about a rewarding and
fulfilling work atmosphere

Today, we deliver 80% of our products within

2 weeks, and we’re pushing toward a goal of
just 3 days by 2027. We’ve also reduced
product complaints by 70%, and we’re
committed to driving that to zero by 2025.

Welcome to IOTAFLOW! Where the essence of our name reflects our commitment to precision Flow Measurement Solutions. Derived from "IOTA", meaning minuscule or minute,
we embody this concept by crafting flow meters with an iota of error. The word "FLOW" underscores our unwavering dedication to designing instruments for everything that could
flows be it Air, Water, Oil, Gas, Steam, or Chemicals. Yes, we have it all.

At IOTAFLOW, we reject the notion of a one-size-fits-all approach. Instead, we embrace a vision where our customers receive bespoke technological solutions without compromise.
To achieve this, we've forged strategic partnerships with ten domain leaders across Europe, Canada, and Japan. These collaborations empower us to offer a diverse range of
cutting-edge technologies without the need to push any particular product & / or technology.

A significant milestone in our journey came in 2019 when we entered into a technical collaboration agreement with renowned European companies like Aflowt & Vzljot. These
partnerships have enabled us to manufacture and distribute their high-quality products (MID & OIML Certified) across India and neighbouring regions, marking a new chapter
in our story of growth and innovation.
