Features
The flow sensors of Type 210 offer a wide range of configuration options for electrical power supply and output interfaces. The vortex flow sensors are maintenance-free due to their design without moving parts, making them resistant to contamination. Moreover, they are characterized by a low pressure drop and exceptionally high measurement accuracy. Optional variants with an integrated temperature sensor are available.
•Flow measurement optionally with voltage, current, pulse, or frequency output
•Excellent media resistance (measuring element without media contact)
•Optionally with integrated temperature measurement
•Temperature-insensitive measuring principle
•Large temperature operating range
•Low pressure loss
•Dirt-insensitive measuring element
•Drinking water approvals KTW, W270, ACS, WRAS, UBA 1+
R290 Ready: This sensor is VDE Mark Approved according to EN IEC 60335-2-40 and designed for safe use in heat pumps with propane (R290) - observe application limits and media compatibility according to data sheet/certificate.
