Flow Switch Offers Largest Switching Value Selection and Widest Valve Seat Design Housing Spectrum

Honsberg has introduced the FF type series flow switch which offers the largest switching value selection as well as the widest housing spectrum with a valve seat design. Additionally, the FF series is low maintenance, long lasting and a low-cost system that gives improved system safety.

The flow switch FF series consists of housing sizes for nominal pipe widths from DN8 to DN50 and freely selectable switching values from 0.41 l/m. The swift reaction times of less than 100 ms supplies a rapid actuation time for applications. An additional highlight of the flow switch is the high switching value repeat accuracy with a minimal pressure loss of less than 0.1 bar.

The FF series of flow switches come in various housing sizes for high-pressure cleaning technology, industrial washing machines and car washes, as well as refrigeration technology and hydraulic applications, in fact suitable for applications within any sector where water is processed.

The simplistic design of the piston valve seat makes it practically maintenance free in all applications. In addition to their fast and precise measurement, the FF series flow switch is a long lasting and low-cost switch making it a preferred choice for applications where flow measurement is required.

Piston valve seat design for low investment costs

With a simple mechanical operating principal enhancing its durability, the FF series flow switch is a versatile instrument. 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 changes that actuates a hermetically isolated Reed switch and generates an electrical signal. The vertical positioning of the Reed switch adjusted at the factory enables recognition of flow rates from approx 2% to 60% of the recommended maximum volume.

With the spring-supported stabilization of the piston and the short installation length of the housing, use is possible in all installation positions. The flow switch FF is ideal space saving solution for high unit counts and high efficiency and has a tamper proof switching value offering high system safety.

Benefits

With a compact, space saving design, the Honsberg flow switch FF series also offers:

  • An average switching frequency of 30 switches per hour
  • Fast reaction: > 1,000,000 switches
  • Usage duration of 30,000 operating hours
  • The switching value adjusted at the factory requires hardly any changes
  • High security with high switching value repetition accuracy
  • Flexibly adjustable on the pressure side in the system
  • Low costs due to dirt resistance and low maintenance

With use in process water in industrial systems, frequent contamination situations arise due to sediments and other ordinary content in the water. The filtration is a recommended design feature. The flow switch FF enables horizontal flow through the housing where the vertical functional design is highly resistant to water contaminants. This results in the filtration efficiency of the overall system being supported giving additional benefits of safety and functional reliability throughout the application.

The flow switch FF can be ordered to meet specific customer requirements, with a guarantee that the flow switch operates precisely as required – individualized and tamper proof. There is no switching value drift with the FF flow monitor, an indispensable advantage in flow monitoring for heat exchangers in cleaning technology applications with hot water systems and it meets applicable specifications for system operation.
