HFS 2500 for Water / Water-based Media
POA
The HYDAC Flow Switch in the series HFS 2500 is based on the variable area float principle. Indeed, the test medium deflects a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted to the outside of the instrument and is, therefore, separate from the flow circuit. So, when the magnet inside the float reaches the pre-set position, the reed contacts will switch.
What's more, to protect it from external influences, a casing, designed to allow steplessly variable adjustments, encapsulates the switch.
Moreover, the instruments in the HFS 2500 series are available in two versions, with 5% accuracy and with 10% accuracy.
In addition, the 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
- Also research & development
