The stainless steel King Instrument 7430 series rotameter utilizes a float and tapered tube design. As a result, the King Instrument 7430 series rotameter has longer and more linear scales, better pointer stability, and 40% greater accuracy than competitively priced products.
Both the 65 mm and 150 mm scaled models of the King Instrument 7430 series rotameter feature borosilicate glass tubes, all stainless steel frames, and horizontal connections. Accuracy of the King Instrument 7430 series rotameter is determined by the scale of the rotameter – the 65 mm scale has an accuracy of ±6% of Full Scale Flow and the 150 mm scale has accuracy of ±4% of Full Scale Flow.
The maximum temperature rating of the King Instrument 7430 series rotameter is 250°F (121°C) when used in gas applications and 200°F (93°C) when used for liquids. The maximum pressure for 316L SS fittings is 200 psig, 130 psig for PVC fittings, and 150 psig for PVDF fittings.
Alarm Options for the King Instrument 7430 Series Rotameter
- Inductive Ring Sensor: Inductive ring sensors are designed to be used with a remote intrinsic safety barrier / switch isolator. These sensors are able to detect the metal float by producing an electromagnetic field within the ring. Ring sensors are available in either proximity or latching format for the King Instrument 7400 series rotameter.
- Fiber Optic Sensor: The fiber optic sensor is housed in a junction box attached to the side of a King Instrument 7400 series rotameter. The sensor uses a pair of fiber optic cables, an emitter, and receiver to transmit the light across the metering tube and back to the sensor. If the light beam is blocked by the float, the sensor output will change. The sensor provides a transistor output that switches the common or negative voltage (NPN) or positive voltage (PNP) to the load. The fiber optic sensor is compatible with all King Instrument 7400 series rotameter float types.
