ALARM OPTIONS:

Inductive Slot Sensor

The alarm mechanism in this flowmeter is an inductive slot sensor. It is a 2-wire, DC, low current device
designed to be used with a switch isolator / barrier.

The operating temperature range for this sensor is -13°F to 158°F (-25°C to 70°C).

Note: We can supply the isolator / barrier upon request, but the user must provide the power supply voltage.
