Reliable Air Flow Measuring through Differential Pressure & Thermal Dispersion
An air flow meter is perfect for taking accurate measurements of velocity and pressure. It gives you an economical solution when it comes to reporting and controlling air flow, providing quick or constant measurements of your HVAC System. Whether you need easy installation or a digital display for readings, Johnson Controls has an air flow meter for you.
As industry leaders, we know that requirements for HVAC air flow monitoring have increased over the years. Given indoor air quality (IAQ) requirements for minimum ventilation of occupied spaces, the need for accurate, reliable air flow measurement is a must-have.
That’s why we offer two methods of HVAC air flow measurement – differential pressure and thermal dispersion. These give you the option to choose how you manage your HVAC system, and provides you with a choice when it comes to effective air flow meter solutions.

The Types of Air Flow Meter Johnson Controls Offer
Air flow meters, also known as mass flow meters, measure the mass of air that goes through a system. They are designed to do this in order to calculate velocity and air pressure. Johnson Controls supplies high-quality measurement solutions in the following forms:
Differential Pressure Air Flow Measuring
A differential pressure (dp) air flow meter utilises a single measurement diaphragm to sense air pressure difference and provide highly accurate readings.
Benefits include:
- Cost-effective solution: Generally more affordable upfront costs compared to thermal dispersion meters and ideal for budget-conscious applications without compromising accuracy.
- Versatility and compatibility: Compatible with a wide range of gases and applications, making it suitable for diverse industries and various environments.
- Proven technology: Well-established technology with a track record of reliability and performance that is widely adopted across industries, ensuring a trustworthy solution for air flow measurement.
- Low maintenance requirements: Typically requires minimal maintenance, reducing operational costs over time and provides a hassle-free solution for long-term use without frequent interventions.
- Easy installation: Straightforward installation process, minimising downtime during setup and can be retrofit in to existing systems, making it a convenient choice for upgrades.

Thermal Dispersion Air Flow Measuring
These measurements are calculated by incorporating two temperature sensors as well as a heat source within the air flow stream. Combining this equipment allows you to gather a fast and extremely reliable mass flow figure, making it a great solution for modern HVAC applications.
Benefits include:
- High accuracy in low flow rates: Excels in measuring low air flow rates with exceptional accuracy and ideal for applications where precision in low-flow conditions is critical.
- Wide turndown ratio: Offers a broad turndown ratio, enabling accurate measurements across a wide range of flow rates, particularly advantageous for processes with variable air flow requirements.
- No moving parts: Lack of moving parts enhances durability and reduces wear and tear, increasing the longevity of the meter and making it a cost-effective long-term investment.
- Energy efficiency monitoring: Well-suited for applications where monitoring energy efficiency is vital and allows for precise tracking of energy consumption, aiding in sustainable and cost-effective operations.
- Digital connectivity: Often equipped with digital communication interfaces, facilitating integration with modern control systems, enabling seamless connectivity for real-time monitoring and data analysis.
