Description
Air flow monitor
RHEASREG® KLGF / KLSW
Electronic duct air flow monitor RHEASREG® KLSW with switching output,
in a plastic housing, for determining the 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 sensors are suitable 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.
