Alarm Options:

Latching Reed Switch
A latching reed switch is available for 7300, 7470, 7480, 7600 and 7900 Series flowmeters. 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.

Switch Specifications
Switch Type: SPDT
Max Contact Voltage: 100 Vdc
Max Contact Current: 0.2 A
