Series SF2 Sight Flow Meters combine visual confirmation of flow with a relay or pulse output. The brass, uni-body construction, one piece composite rotor, and ceramic shaft delivers durability with broader chemical, temperature, and pressure capabilities. For specific flow setpoint switching, select SF2-1 meters with a SPDT relay output. Setpoints are fully adjustable over the specified flow range. The dynamic operation of the rotor guards against jamming and false actuation. For flow rate monitoring or metering applications, select SF2-2 meters with a pulse output proportional to the rate of flow. The 4.5 to 24 VDC pulse output is compatible with most digital logic families.

Grâce à son rotor, l’OPTIFLUX permet, à travers un cylindre de verre, la visualisation de la circulation d’un liquide.
L’OPTIFLUX est équipé d’un dispositif de nettoyage par racleurs incorporés permettant d’éliminer les impuretés.
Il suffit de tourner le cylindre de visualisation (système breveté) de 180°, de manière à concentrer les impuretés sur deux fentes étroites qui seront nettoyées par le fluide en circulation. Des joints toriques autolubrifiants assurent l’étanchéité entre les deux éléments et il est possible de tourner facilement le cylindre, même à pression maximum.
