Air flow monitor RHEASREG® KLGF / KLSW
Electronic RHEASGARD® KLGF duct air flow transmitter with active output, in an impact resistant plastic housing, optionally with/without display, for determining flow velocity in m/s. The measuring transducer converts the measured value into a standard signal of 0-10 V.

ElectronicRHEASREG® KLSW duct air flow monitor with switching output (one-step or two-step relay), in a plastic housing, for determining flow velocity in m/s. Fine adjustment of the measuring range end value by the user is possible with the help of a potentiometer.
The flow sensor devices are suitable for monitoring or controlling airflow in ducts, at ventilators and dampers, for flow-dependent monitoring of humidifiers and electric heating registers according to DIN 57100, part 420, or for use in connection with DDC systems.
