Unlike volumetric meters, they determine the actual mass of the medium regardless of variations in pressure or temperature, ensuring consistent and reliable measurements. Industries such as oil & gas, pharmaceuticals, food processing, and chemical manufacturing depend on mass flow meters to enhance efficiency, maintain safety, and optimize resource usage.
At Pneucleus Technologies LLC, we provide reliable mass flow meters for gases that deliver high-precision results. These devices are ideal for monitoring and optimizing flow processes across industrial sectors. Their advanced design ensures durability, low maintenance, and superior performance.[/vc_column_text][vc_column_text css=””]
How Do Mass Flow Meters Work with Gases?
Pneucleus Mass flow Meters are based on the heat transfer from a hot wire centered between two resistive thermal detectors (RTD’s), one upstream RTD and one downstream of the hot wire. This is called a hot-wire anemometer. At zero flow the heat plume from the hot wire heats both RTD’s equally causing the resistance of each RTD to be the same. A precisely regulated voltage is applied to two legs of a bridge circuit where at the top of each leg is a laser trimmed pull-up resistor that connects to either the upstream RTD or the downstream RTD. The current through each leg creates a voltage drop that is equal and balanced across each RTD at zero-flow. When gas begins to flow, the upstream RTD is cooled which decreases its resistance and therefore its voltage drop. The downstream RTD temperature increases as the heat plume begins to lean toward it. It’s resistance increases resulting is a larger voltage drop.
The difference between the upstream voltage and the downstream voltage is proportional to the flow rate across the anemometer. These variations are dependent on the mass, thermal conductivity and the velocity of the gas that is flowing through the anemometer. By measuring the gas flow with a precisely calibrated flow standard that is calibrated for the gas type under test, the anemometer voltage differential can be precisely calibrated to output a voltage correlating to the mass flow rate measured by the precision flow standard. The hot-wire is regulated to maintain a temperature 160 degrees above ambient. This is how mass flow can be measured with little concern about the ambient temperature or pressure.
This precision makes mass flow meters ideal for applications requiring exact quantification of flow in both industrial and laboratory settings.

FAQs
What are the key advantages of using a mass flow meter over a volumetric flow meter?
Mass flow meters offer higher accuracy because they are unaffected by temperature and pressure variations, making them ideal for precise fluid measurements in industrial processes.
Can mass flow meters measure low flow rates?
Yes, mass flow meters, especially thermal types, are highly effective for low flow rate measurements with great sensitivity.
How do temperature and pressure impact thermal mass flow meters?
Thermal meters rely on heat transfer, so temperature and pressure changes can influence the accuracy if not calibrated correctly using precise & traceable Mass Flow Standards.[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][vc_column][/vc_column][vc_column][/vc_column][vc_column][/vc_column][/vc_row]
