Teledyne Hastings Instruments brings decades of experience to offer a full line of thermal mass flow meters and controllers. Our products provide solutions for a wide range of app​​lications which include high and low flow ranges, corrosive gases and low dP requirements. With the assistance of our experienced application engineers and global sales network, we will help you find a reliable, repeatable, and durable solution for applications in both laboratory and industrial environments. Your needs can be met by using quality flow instruments designed and manufactured by Teledyne Hastings​.

All Teledyne Hastings mass flow meters and controllers are configured for your specific conditions. You can begin selecting a flow instrument by finding what range below your application fits into. Solve your application challenges with our trusted line of thermal mass flow meters and controllers. If you require any assistance, please feel free to​ ​contact our experienced application engineers for assistance.​​

All Teledyne Hastings mass flow controllers and meters are configured for your specific conditions to give an easy-to-use flow instrument that provides an accurate flow measurement. To see available options, refer to the back section of each product bulletins. Some basic considerations when choosing a flow instrument include:

• Full Scale Range and Gas Type
• Reference Conditions (Temperature & Pressure)​
• Upstream & Downstream Pressure (Only applicable to Flow Controllers)

While there are additional factors that should also be considered, such as communication, pressure drop and ambient temperature, these three factors are a great place to start when determining which flow instrument is suited to your application​.

If you need help converting mass flow into volumetric flow or converting it into different units, then Teledyne Hastings has developed a thermal mass flow calculator to help determine your new flow rate. In standardized volumetric flow units (sccm, slm, scfm,), the reference conditions, or “STP" temperature and pressure, define the amount of gas by determining the number of molecules using the Ideal Gas Law. In many cases, the selected reference conditions are 0°C & 760 Torr. However, other reference conditions are also used, such as 25°C & 760 Torr, or 70°F & 760 Torr.
