Introduction
In industries where fluid measurement accuracy is critical — such as oil & gas, chemicals, petroleum, and water treatment — choosing the right flow meter can make or break operational efficiency. Among the many technologies available, positive displacement flow meters stand out for their high precision, reliability, and robustness.
And when it comes to reliable PD flow meter manufacturing in India, Fluidyne is a name that leads the way. With decades of experience, cutting-edge engineering, and a reputation for consistent performance, Fluidyne continues to be a preferred positive displacement flow meter manufacturer across multiple industries.
What is a Positive Displacement Flow Meter?
A positive displacement (PD) flow meter directly measures the volume of liquid passing through it. It works by trapping fixed amounts of fluid and counting the number of times the chamber fills and empties.
? Think of it like this:
It's similar to filling and emptying a bucket over and over — a highly accurate, mechanical method of flow measurement.
Why Choose Positive Displacement Flow Meters?
High Accuracy (up to ±0.1%)
Works Without Power in Basic Configurations
Ideal for Viscous Fluids like Oil, Fuel & Chemicals
Minimal Flow Conditioning Needed
Durable for Harsh Industrial Environments
Whether you’re measuring diesel, lube oil, solvents, or additives, PD meters give you consistent, tamper-proof results.
