SF Flow Meter & Flow Switch
SF-M: Instantaneous flow indicator
SF-MA: Instantaneous flow indicator + lower (or upper) microswitch
SF-MAA: Instantaneous flow indicator + lower & upper microswitches
.Most suitable for opaque liquids (oil,etc), high-temperature and high-pressure fluids. No restrictions on flow direction.
.The contact of the SF-MA.MAA standard flow switch is internally variable, but an external variable type can also be manufactured for frequent variations.
.Complete waterproof type (IEC IP67) is also manufactured for outdoor or severe-atmosphere use.

Microswitches used for contacts are classified into the following three types according to diameter and flow rate:
.15A : 125, 250 or 480 VAC / 0.5A: 125 VDC / 0.25A: 250 VDC
.5A : 125 or 250 VAC / 0.5A: 125 VDC / 0.25A: 250 VDC
.10A : 125 or 250 VAC
For use in high vibration places, use vibration-proof type.
