Belimo 22PF-1UF - ultrasonic flow sensor

Belimo 22PF-1UF flow sensor

The 22PF-1UF uses ultrasonic flow measurement in closed cold and hot water systems. It is designed for water and water-glycol mixtures with a concentration of up to max. 60% vol. The sensor continuously measures the glycol content in the medium and takes it into account when measuring flow.
