Piston flow switch F series

for gasfor liquidshorizontal

Piston sensing element Vertical or horizontal mounting Liquid and gas media application Nickel plated brass, St. Steel or PVC body The flow of the F-series have been designed to allow an easy flow control and a safe signal in the absence of flow. The electric part is physically separate from the mechanical and the actuation of the contact takes place magnetically. The electric head, in case of need, can be replaced without removing the instrument from its installation. • Fixed set point • Easy replacement of the electrical contact • Low pressure drop • Versions for vertical or horizontal operation • Use of liquids and gases MOUNTING Carefully observe the flow direction shown by the arrow on the body of the switch. In the case of vertical mounting the flow direction must always point upwards. Before installation, bleed the system to prevent any impurities interfere stagnant and / or block the internal piston. In the presence of impurities in the fluid is recommended for installation upstream of the flow of a filter in the magnetic trap (see bulletin of magnetic trap Filter ZV). Always make sure that the switch is not mounted in direct contact with ferromagnetic surfaces that interfere with the proper functioning of the instrument.
