DWYER USA SS Horizontal Level Switches, For Compatible Liquids., Certification : Yas

horizontal level switches

series f6 & f7 level switches - horizontal/specialty

low cost, hermetically sealed contacts

the series f6 & f7 horizontal float level switches are designed to mount through the walls of tanks and other vessels. Internally mounted models f6-hps-11, f6-mhs and f7-ss6 are secured to the wall of the tank or vessel from the inside while model f6-hps-21 is mounted from the outside (externally). Models f7-hss and f6-mhs2 can be installed internally or externally.

the series f6 & f7 specialty float level switches are designed for unique applications. Model f7-ss5b/bnc can be used with viscous liquids or liquids with suspended metal particles. Use model f7-ll for low level detection (≥ 5/8"). The non-intrusive bottle style f7-eb mounts completely outside the tank at the actuation level. Suspend model f7-wbb in stand pipes or sumps for leak detection or drop into wells for ground-water monitoring.

product applications

• water level monitoring
• oil level control
