The HFS is a sensor with a hygienic design that is easy to flush. It is based on the highly dynamic differential pressure technology of the PFS and can measure up to 10 L/min. The combination of the HFS with a dynamic valve is ideal for dosing small quantities at high frequency (up to 50 Hz).
The HFS measures with a sampling frequency of up to 20 kHz and can resolve volumes from 0.1 ml to L with high accuracy.
Features:
- Dynamic measurement with response times < 1 millisecond
- Hygienic design
- Volume flow measurement up to 10 L/min
- Exact volume integrals from 0.1 ml
- For water, ethanol and other low-viscosity media (up to 50 mPas)
- Not susceptible to gas bubbles
- Integrated temperature and pressure measurement
- Suitable for the food sector
- Sterilization by hot flush up to 70°C and 3 bar and with ethanol
