Abstract

1,088,427. Magnetic switches. ALLEN WEST AUTOMATION Ltd. Dec. 23, 1965 [Dec. 23, 1964], No. 52227/64. Heading H2B. A fluid flow detector comprises a housing 11 defining an upright passage 19 having an inlet port 12 and an exit port 21 part way along the passage. A loose-fit gravity biased piston 23, which may be raised by fluid flow to clear the ports 21, carries a permanent magnet 23a which operates a sealed magnetic reed contact unit (not shown) in a passage 24. The contact unit may be mounted in a block adjustably secured on the tube in which the permanent magnet moves (Fig. 5, not shown).
