HYSTERESIS (Δ FLOW RATE TO ACTIVATE/DEACTIVATE SWITCH)
≈ 10% at upper end of flow range
≈ 30% at lower end of flow range
DIFFERENTIAL PRESSURE DROPS ACROSS UNIT
Under normal operating conditions:
≈ 1″–3″ pipe, less than 0.5 psi
≈ 4″–10″ pipe, negligible
WORKING LINE PRESSURE:
50 psi max., operating @ 180˚F 100 psi max. non-operating @ 180˚F Pressure over 50 psi can affect the switch point range
ELECTRICAL SWITCH CHARACTERISTICS
SPDT (single pole double throw) 13A, ½ hp @ 125VAC ½A @ 125VDC (tungsten lamp load) 10,000,000 Operations Median
