FSV10AR30 is an inline flow switch designed for G1" BSP pipe connections that monitors liquid flow and controls a pump or other equipment via relay output. The device features a minimum startup flow rate of 3.0 l/min, with a maximum pressure rating of 8 bar and maximum temperature of 85°C, utilizing a brass flow tube with polyamide enclosure. It provides an adjustable pump stop delay ranging from 0 to 10 seconds and operates on supply voltages of 24 or 240 Vac, with a maximum switching power of 1 kW and switching current of 4 A for motor loads. The switch must be mounted vertically with upward flow direction, making it ideal for pumped systems where automatic flow-based control and protection against dry-running conditions are required.
