Common Industries


Fox Thermal Flow Meters Provide

Direct Mass Flow Measurement

Fox Thermal thermal gas mass flow meters are ideal flow measurement devices for air or gas. Fox meters utilize the thermal sensing principle, a proven, accurate direct mass flow measurement technology. No need to perform additional calculations to track flow!

Flexible Features

Fox Thermal mass flow meters with Gas-SelectX® and CAL-V™ calibration validation make it easy to change gas mixtures and retain measurement accuracy while avoiding costs associated with shutdowns for maintenance, replacement, or recalibration.

Reliability and Repeatability

Fox Thermal meters have a proven track record for repeatable measurement, outstanding accuracy, and low maintenance costs. Our meters provide a large turndown rate, with a repeatability of up to 1,000:1 (typically 100:1) for very high velocity or for very low flow rates
