Kobold SMO and SMW Displacer Flowmeter / Switch

Kobold SMO Displacer Flowmeter Switch
SMO and SMW Displacer Flowmeter Switch

The KOBOLD flowmeters and switches models SMW-.. and SMO-.. operate in the same way as the flowmeter model SMV-… The extra advantage of universal mounting has been added, that is, the direction of flow can be horizontal (model SMW-..) as well as from top to bottom (model SMO-..). This is achieved with a return spring.
