Flow switch GENERAL CHARACTERISTICS The flow switch FCM was built to enable a simple control of the flow rate and a fast signal in the absence of flow. The electrical part is physically separate from the mechanical and the contact is magnetically actuated. The electric head has a bayonet fixing system and, in case of necessity, can be replaced without removing the instrument from its installation. ● ● ● ● ● No calibration needed. Easy replacement of the electrical contact. Low pressure loss. Versions for both vertical and horizontal operation. Can be used both with liquids and gases. Vertical mounting with flow direction from bottom to top. Horizontal or vertical mounting with flow direction from bottom to top TECHNICAL DATA Body Process connection Sensor Accuracy Max.

ELECTRICAL DATA Reed contact Reed contact data Connection DIN plug protection IP65 On request The DIN cap is supplied in a separate kit INSTALLATION AND MAINTENANCE Drain the hydraulic circuit before installation. Do not mount the switch in direct contact with ferromagnetic surfaces. Proceed with the assembly, taking care to use only a hexagonal wrench for fixing metal fittings. In case of electrical failure replace the electrical head making sure of the happened hooking bayonet. ● ● KIT/FCM We reserve the right to change the data without notice Name + N. of setting Nominal setting l/min Process connection + Type of installation DIN cap optional mounting kit
