DESCRIPTION GE-324A/B series thermal flow sensor is adopts heat exchange principle design, according to the thermal diffusion size detection the size of flow.When the liquid velocity exceeds the user setting value relay action , the realization of the flow detection and control. Can be widely used in petroleum , chemical , electric power , water treatment , metallurgy metallurgy , paper making , shipbuilding and boiler industries pipeline flow detection.

= Shut down the valve for pipeline, install the flow sensor. = Open the flow sensor power supply, preheat for above 1 minute. = Rotate the “SET” transmission screw, Until just the red LED bright. = Rotate the valve for pipeline, waiting for above 1 minute, make sure the flow stability. Rotate the “MAX” transmission screw ,Until 4 green LED all bright. = Shut down the valve for pipeline or open the valve for pipeline to control the flow size below the set point, waiting for above 1 minute, the flow sensor shows only the red LED bright. if it can’t be change to the red LED bright, could be counterclockwise adjust

=Alarm point can be adjusted continuously, directly through the drive screw adjustment = Small volume, convenient installation, completely waterproof =Applicable for wide range of diameters pipe = Max pressure withstand up to 100 bar = Set point adjustable freely = The anti-limescale sensing probe applicable even for poor quality water = With high accuracy & stability = 6 LED for visual flow indication

TECHNICAL DATA

= Open the valve for pipeline, the flow sensor show for the green LED bright, it’s seting correct, the number of green LED bright represent the
