Available for 1/4- to 1-in. pipe sizes, Clark Solutions DN series liquid vortex flow meters feature molded PPA construction and ETFE and EPDM wetted parts. Suitable for water- and water-glycol-based heat exchange systems with usual additives, they utilize piezoelectric sensors embedded in an ETFE vane located downstream of a bluff to detect the generated vortices. A flow factor is provided to convert frequency to volume flow rate for each model size. An optional platinum RTD temperature sensor is available.
