flowguardPRO 4-20

the flowguardPRO sets new standards for safe and easy installation with its patented non-return protection. this technology ensures the sensor can only be pushed in one direction during the installation and cannot return at all, even under pressure. a special o-ring ensures no compressed air can escape and makes it extremely easy to position the sensor precisely.

inline airflow meter based on thermal massflow measurement

housing with evaluation electronics discharched up to 10m to the sensor element
