Robust und flexible
The simple mechanical operating principle of the piston valve seat design means that it is practically maintenance-free in all applications. The volume flow raises a piston (fitted with a magnet) out from a valve seat against a spring force. The stroke causes a magnetic field change that actuates a hermetically isolated Reed switch and generates an electrical signal With the spring-supported stabilisation of the piston and the short installation length of the housing use is possible in all installation positions. The range consists of housing sizes for nominal pipe widths from DN 8 to DN 50 and freely selectable switching values from 0.4 l/m.
Fast, precisely und long-lasting
You benefit from a quick response <100 ms and a high switching value repeatability > 1,000,000 switching operations. With an average switching frequency of 30 switching operations per hour, the service life is min. 30,000 operating hours. The ideal flow monitor with low pressure loss to ensure reliable operation of your application.
Piston valve seat design for low investment costs
The flow switch FF is designed as a device family with a piston valve seat design. As if made to be used in large quantities with outstanding economy. The devices are independent of location and can be installed as required.
Your benefits at a glance
No manipulation possible due to the factory-set switching value
High level of safety thanks to high switching value repeatability
Can be used flexibly, also on the pressure side in the system
A wide range of switching values offers extensive application options
Low operating costs due to freedom from maintenance
Investment security thanks to robust, safe and durable construction
When industrial water is used in industrial plants, there are often pollution situations caused by sediments and other common water contents. Filtration is therefore a recommended component of the system. The flow switch FF enables horizontal flow through the housing, so that the vertical functional construction is only slightly exposed to water contamination. This supports the filtration effectiveness of the entire system.
Robust, durable, low-maintenance - so that you benefit from greater safety and freedom from interference in your application.
