Description

The molded polysulfone King Instrument 7330 series rotameters are offered with direct reading scales for flow rates from 0.1-1.0GPM to 10-100GPM (water). The King Instrument 7330 series rotameters' connections are vertical (in-line type) with PVC or PVDF union ends which greatly simplify installation and maintenance. With the Teflon float option, the King Instrument 7330 series rotameter is excellent for applications where no metal is preferred.

PVC fittings are standard to the King Instrument 7330 series rotameter. These fittings are rated for a maximum temperature of 130°F (54°C) and maximum pressure of 150 psig for sizes 41-72W and 125 psig for sizes 90-103W. PVDF fittings are available as an option to the King Instrument 7330 series rotameter. PVDF fittings are rated for a maximum temperature of 200°F (93°C) and a maximum pressure of 150 psig for 41-72W and 125 psig for sizes 90-103W.

Alarm Option – Latching Reed Switch

A latching reed switch is available for all King Instrument rotameters in the 7300, 7600, and 7900 Series. The switch is reed type and uses a biasing magnet to create a latching feature. The switch is classified as a simple apparatus by UL, FM, etc. and may be suitable for hazardous use when connected to an intrinsic safety barrier. Check your local electrical code for wiring specifications.
