Industrial gas measurement can be complex, expensive, and error-prone. Traditional flow meters often fall short in dynamic, high-temperature environments. Ultrasonic Flow Meter technology from ESEGAS provides an accurate, maintenance-free solution.

The ESEGAS Ultrasonic Flow Meter is a non-intrusive, high-precision instrument engineered for harsh industrial environments. It enables continuous, contact-free measurement of gas flow, making it a preferred solution in power plants, chemical facilities, and emission control systems.

Even if you’re familiar with standard flow measurement technologies, the innovation behind ESEGAS products—particularly the LEUF‑200 series—offers a next-level understanding of flow dynamics in industrial plants. Let’s examine why ESEGAS stands out.

How Does the ESEGAS Ultrasonic Flow Meter Work?

The ESEGAS Ultrasonic Flow Meter operates on the principle of the transit-time (or “time-of-flight”) method. In essence, it measures the difference in the travel time of ultrasonic pulses between two sensors—one transmitting upstream, the other downstream. When gas flows through the pipe, it accelerates the downstream signal and delays the upstream one. By comparing the time difference, the meter calculates the velocity of the gas and converts it to volumetric or mass flow.

Unlike intrusive flow meters that suffer from pressure drop, wear, or contamination, the ESEGAS system uses externally mounted transducers. This non-invasive configuration ensures no contact with the gas, preserving the integrity of both the measurement and the medium.

Advanced signal processing technologies in ESEGAS products allow for high repeatability and exceptional noise immunity, even in turbulent or particulate-laden flows such as flue gas or combustion exhaust.

In Which Industrial Applications Is ESEGAS Most Widely Used?

The ESEGAS Ultrasonic Flow Meter—especially the LEUF‑200 model—is purpose-built for the most demanding industrial gas measurement environments.
