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.
