The LVCN-141 flow switch controller is commonly used as a low flow shut off for pumps or process protection with a single switch input.

The LVCN-131 flow switch controller is commonly used as a dual low flow shut off for pumps or process protection with two independent switch inputs.  This model also has a 3rd input (2B) which can be latched with input 2 (2A) so Relay 2 requires both Inputs 2A & 2B to be in the same state before it will switch.  This relay logic is ideal for automatic filling or emptying of tanks.

Select the FST-200/300 or FST-320 series flow switches only for use with these remote relay controllers.

For level sensors select capacitive: LVC 152 series or ultrasonic: LVU150 series level switches.
