Double Glazed Electric Flow Indicators

The Bamford Ajax series of Electrical Flow Indicators are a generation of ruggedly constructed devices for automatic control and reliable protection of machinery and plant. The units can be mounted in horizontal, vertically upward or vertically downward attitudes. The functionally designed enclosure is standard on all models to meet the arduous conditions experienced in various sections of industry. Single or double switchbox versions are available. The standard precision snap action microswitch is a single pole double throw type; however, one or two microswitches with silver plated noble metal contacts may be fitted to provide versatility of switching circuits, which may be factory set or can be field adjustable.

The flow indicator is specifically designed to warn instantly of a failure or change of flow in a liquid circuit. Based on simple principles, the flow induced movement of a hinged flap is converted by eccentrically mounted bearings into a rocking motion of a vertical rod, which, pivoted about a special double seal, operates at its upper end the adjustable microswitch, or switches. The materials of construction cater for the majority of liquids, with the toughened glass viewing ports offering a visual indication of flow. Double glazed versions are also available.
