Best 8 Thermal Mass Flow Meters

Thermal mass flow meters are instruments used to measure the flow rate of gases or liquids based on the principle of thermal dispersion. These meters operate by measuring the heat transfer properties of the fluid flowing through a pipe or conduit.

Thermal mass flow meters can be used when you require

Direct Mass Flow Measurement

Thermal mass flow meters provide direct measurement of mass flow rate, without the need for additional pressure or temperature compensation. This eliminates the need for complex calculations or additional sensors, simplifying the measurement process.

Wide Flow Range

Thermal mass flow meters have a wide turndown ratio, allowing accurate measurements across a broad range of flow rates. They can accurately measure both low and high flow rates, providing flexibility in various applications.

High Accuracy and Precision

Thermal mass flow meters offer high accuracy and precision in measuring gas flow rates. They can provide reliable measurements even at low flow rates, ensuring precise control and monitoring of processes.

Minimal Pressure Drop

Thermal mass flow meters have a low-pressure drop, meaning they do not significantly impede the flow of gases through the system. This is particularly important in applications where maintaining system pressure is crucial.

Wide Gas Compatibility

Thermal mass flow meters can measure a wide range of gases, including both clean and dirty gases. They are compatible with various gases, such as air, natural gas, nitrogen, oxygen, and more.

No Moving Parts

Thermal mass flow meters have no moving parts, reducing the risk of mechanical failure or wear and tear. This results in increased reliability and decreased maintenance requirements.

Quick Response Time

Thermal mass flow meters provide a fast response time, allowing for real-time monitoring and control of gas flow rates. This is especially beneficial in applications where rapid changes in flow rates need to be detected and controlled.

Here are the Best 8 Thermal Mass Flow Meters disused for you.

1, Thermal dispersion mass flow meter

Gas mass flow meters are available in two configurations: insertion thermal mass flow meters and in-line thermal mass flow meters. In both cases, the thermal dispersion mass flow sensor probe is inserted into a gas-filled pipe stream, duct, or stack. The probe features two primary sensors, referred to as resistance thermometers or resistance temperature detectors (RTDs), which are responsible for temperature measurement. The sensors are positioned toward the tip of the meter and are utilized to accurately monitor the temperature within the gas flow.

2, Remote read gas meter

Remote flow meters are specifically designed for hazardous environments where the exposure of individuals to the flow meter enclosure can pose a risk. Additionally, they offer convenient access for easy maintenance and monitoring. To ensure safety, gas flow totalizers are positioned in easily reachable locations with secure conditions. Some remote read gas meters may even include explosion-proof enclosures, depending on the specific model. The remote enclosure houses all the necessary electronics and features a connected cable for the remote display, enabling remote monitoring and control.

3, Natural Gas Mass Flow Meter

Natural gas flow meter is specifically designed to accurately measure the flow of natural gas and provide valuable insights into its energy content. By precisely detecting pressure drops and directly measuring mass flow, our flow meter enables you to determine the heating value of the gas. This information allows you to optimize the efficiency of boilers and burners by using natural gas with high-quality energy content. With more accurate measurements, you can save both time and money. This flow meter is also suitable for handling liquefied gases, offering versatility in various gas applications.

4, Low pressure gas flow meter
