Hydac Flow Switch series HFS 2500 for water-based media

Click2Contact

The Hydac Flow Switch in the series HFS 2500, suitable for water-based media, 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 steplessly variable adjustment. The instruments in the series HFS 2500 are available in two versions, with 5% accuracy and with 10% accuracy.

Areas of application are to monitor flow rate in fluids (water/water-based) in the following areas, amongst others: cooling systems and circuits; hydraulic systems; pumps; welding machines and laser systems; medical technology; pharmaceutical industry; chemical industry; research and development.

Features include: accuracy ≤±5 % or ≤±10% FS; optional mounting position; high level of function reliability; high level of switching accuracy; stepless switch point setting by user; high-pressure resistance; threaded connection; ATEX version also available for use.
