M-61-T Series
Fixed Flow Setting Information
Electrical
This model is a FIXED flow switch. The flow set point is
fixed at the factory and is NOT field adjustable. Proper
calibration of the set point requires the following
information. When purchasing a flow switch, use the
“Set Point Calibration” form on page i-vi or provide this
information on the purchase order.
• Calibration set point,
• Increasing or decreasing flow,
• Fluid type (i.e. liquid or gas),
• Density or specific gravity,
• Viscosity,
• System pressure and temperature,
• Flow direction (i.e. upward or downward), and
• Mounting orientation (i.e. horizontal or vertical).
