raptor flow-captor 4220 SI02 + 4020.46 The flow-captor type 4220 S102 + 4020.46 is a family of compact, precise measurement flow switches with analog temperature output and analog display. They operate based on the calorimetric principle. The flow-captor allows to set an exact flow set-point and will display simultaneously the flow rate up to the lowest flow conditions. The 4020.46 has a separate, adjustable temperature output. • precise switching flow monitor for water based solutions • high accuracy also under low flow conditions • separate adjustment for "range"and "set-point" • analog display of actual flow and display of them adjusted set-point value • LED display for output status • separate, adjustable temperature output • ISO 9001: 2015 weber Sensors GmbH ■ Strohdeich 32 ■ D-25377 Kollmar ■ Tel.: +49 4128-591 ■ Fax: -593 eMail: [email protected] Technical data subject to alteration! • Rev.

Turn temp.-potentiometer slowly clockwise until the LED switches to green (Switch point). For example: If the medium temperature is 20 °C the switch-point will be at 20 °C ± 2,5 °C. weber Sensors GmbH ■ Strohdeich 32 ■ D-25377 Kollmar ■ Tel.: +49 4128-591 ■ Fax: -593 eMail: [email protected] Technical data subject to alteration! • Rev.
