Used on hlvw refueller. sculmatic mkiv flow sensing switch switch activates air throttle actuators to increase truck engine from idle to full pumping speed when delivernozzle is opened
lever arm spot switch double throw; pretravel .151 in max; operating point .603 in nom; overtravel .082 in min; movement differential .030 in max; temp rating 85c min
Used on an/gsc-70(v)1, isil. the roton air flow switch is actuated by air velocity rather than air pressure.a snap action switch is actuated when the velocity pressure against the vane moves it in the direction of the air flow. as the vleocity of the air flow decreases for any reason the vane moves back to its original position
horizontal media flow left to right or right to left. can be fitted with set point switches triggering on flow rate. actuated by a magnet in the float. same magnet can be used to coupleto an external flow indicator
