Hydac HFS 2500 flow switch for water-based media
The HFS 2500 flow switch is based on the variable area float principle and can be used in any position in the system. The test medium moves a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted to the outside and is therefore separate from the flow circuit. When the magnet inside the float reaches the preset position, the reed contact will switch.
To protect it from external influences, the switch is encapsulated in a casing designed to allow stepless variable adjustment. The instruments in the series HFS 2500 are available in two versions, with 5% accuracy and with 10% accuracy. The connections to the system are threaded and an ATEX version is available.
Areas of application are to monitor flow rate in water or other water-based fluids, examples including cooling systems and circuits, hydraulic systems, pumps, welding machines and laser systems.
