The electronic airflow monitor RHEASGARD
®
KLGF measures the flow velocity in m ⁄ s and converts the measurement signal into a standard signal
of 0 - 10 V (flow measuring transducer). This flow sensor is optionally available with or without display.
RHEASREG
®
KLSW provided with a switching output (one-step or two-step) is designed as flow sensor ⁄ flow monitor. Fine adjustment of the upper
range limit by the user is possible at a potentiometer.
The airflow monitor ⁄ airflow sensor is used for monitoring or controlling airflows 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.
