Reliable flow monitoring starts with a switching point that can be set clearly and repeated with confidence. Designed for liquid media, this mechanical flow switch uses contactless actuation of an adjustable Reed contact and offers exact switching value setting via a 180° scale and setting diagram.
The robust cast iron flange housing supports use in industrial pipework from DN 15 to DN 150. Switching ranges for H2O cover 2-950 l/min, with recommended Qmax. values up to 2000 l/min and a tolerance of ±5 % of full scale. PN 16 pressure resistance and media temperatures from -20...+120 °C give the device a practical operating window for water-based applications.
For stable operation, the flow switch is intended for horizontal flow as standard and requires straight calming sections of 5 x DN in the inlet and outlet. Options such as ingress protection (IP65), temperature indication, temperature monitoring and internal parts made of brass or stainless steel allow adaptation to the application.
The device monitors flow in liquid media using contactless actuation of an adjustable reed contact.
The product family is available with flange connection in nominal widths from DN 15 to DN 150.
H2O ranges are selected by version and apply to horizontal flow with decreasing flow rate.
The standard connection uses a DIN 43650-A / ISO 4400 plug and a changeover Reed switch.
Standard mounting uses horizontal flow. Other installation positions are possible, but they affect the switching point or range.
Water is specified as the standard medium. Oils and aggressive media are available on request.
A straight calming section of 5 x DN is required in the inlet and outlet. Filters are recommended for contaminated media.
Options include signal lamp, ingress protection (IP65), temperature indication, temperature monitoring and higher media temperature resistance.
