King Instruments 74812342W0 Glass Tube Rotameter

The King Instruments 74812342W0 Glass Tube Rotameter is a glass-tube flowmeter configured with a stainless steel enclosure, delivering visible flow indication with rugged protection for demanding environments. In a typical rotameter design, a calibrated glass tube houses a float that rises with increasing flow, and the float’s position against a scale indicates the flow rate. The stainless steel enclosure surrounding the glass tube adds durability and protects against environmental exposure while preserving clear observation of the flow. The part number 74812342W0 uniquely identifies this unit within King Instruments’ lineup, ensuring compatibility with systems that require a glass-encased rotameter built for industrial use. The combination of transparent viewing tube and protective enclosure supports straightforward visual monitoring and robust service in environments where non-electronic flow indication is preferred.
