Industrial facilities rely on precise gas flow measurement to improve operational efficiency, maintain environmental compliance, and optimize process performance. An online pitot tube gas flow meter is one of the most reliable solutions for continuously monitoring gas velocity and flow in stacks, ducts, and pipelines. Designed for demanding industrial environments, this technology delivers accurate, real-time data that supports better decision-making and regulatory reporting.
At EseGas, we provide advanced gas flow measurement solutions engineered for long-term performance across a wide range of industrial applications. Whether you're monitoring flue gas emissions or managing combustion processes, selecting the right gas flow meter can significantly improve operational reliability.
What Is an Online Pitot Tube Gas Flow Meter
An online pitot tube gas flow meter is an industrial instrument that measures gas flow by detecting the pressure difference between the total (stagnation) pressure and the static pressure inside a flowing gas stream. Using this differential pressure, the system calculates gas velocity and volumetric flow with high accuracy.
Unlike portable instruments, an online system is permanently installed and continuously measures gas flow without interrupting plant operations. This makes it an ideal choice for facilities requiring real-time monitoring and automated data collection.
How Does a Pitot Tube Gas Flow Meter Work
A pitot tube gas flow meter operates based on the principle of differential pressure measurement. As gas flows through a duct or stack, the pitot tube measures:
Total pressure
Static pressure
Differential pressure
The transmitter processes these readings and calculates the gas velocity. Combined with duct dimensions and compensation for temperature and pressure, the system accurately determines the total gas flow rate.
Modern systems also integrate temperature and pressure sensors to improve measurement accuracy under changing operating conditions.
