Measuring only 1˝ x 2-3/4˝, these compact switches are ideal for use where space
is at a premium. Designed for use with water and oil, these switches are suitable for
high volume OEM applications. They are ideal for coolant or lubricant flow monitoring
in portable equipment and many other applications with space constraints.

How To Order – Standard Models
Specify Part Number based on flow setting and switch operation.
Liquids other than water: Special calibration is available from Gems for media other
than water. Please consult factory with your requirements, including flow media,
operating pressure, flow set point and liquid viscosity (SSU).
Notes:
1. Flow settings are calibrated using water @ +70°F on increasing flow, with units in a vertical position
2. Care should be taken by specifiers to ensure fluid compatibility with the above listed wetted materials.
3. Use of 50 micron filtration is recommended.
