PF2M7 is a digital flow sensor compatible with air, nitrogen, argon or carbon dioxide. PF2M7 refreshes the legacy PFM7 with several enhancements. The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage. Dimensions and weight have been reduced, especially beneficial when installed on moving tooling.
