Where it works
HNF20‑A Turbine Flow Sensor – where it's used:
Cooling circuits. Lubrication systems. Fuel transfer lines. Chemical dosing skids. Laboratory test rigs.
The HNF20‑A fits into industrial automation, petroleum handling, chemical processing, metallurgical plants, and R&D environments.
Wherever you need reliable flow data and the ability to act on it - alarms, shutoffs, or data logging - this sensor delivers.
In cooling water applications, for example, loss of flow can damage equipment and drive up maintenance costs.
The HNF20‑A monitors flow continuously and triggers an alarm or stops the machine before damage occurs. Consistent flow also stabilises manufacturing processes and reduces energy consumption.For fuel and petrochemical applications, the anti‑interference version (available for DN50 and smaller) stays stable even near variable frequency drives. For high‑temperature processes, versions are available up to 180°C.
What sets it apart
Programmable alarm limits
Set upper and lower flow thresholds directly on the device. No software, no laptop - just the keypad on the display.
Optional temperature measurement
Add temperature monitoring without adding another instrument. Flow and temperature, side by side.
304 stainless steel housing. 3Cr13 turbine. IP67 ingress protection. It handles water, dust, and vibration without complaint.
Multiple outputs, one sensor
PNP, NPN, 4‑20mA, 0‑10V, pulse, frequency, and RS485. Whatever your PLC or control system expects, the HNF20‑A speaks it.
Wide range of process connections
External thread, internal thread, flange, or hygienic clamp. You don't redesign your piping - you pick the connection that fits.
Response time down to 10 ms. Catch rapid fluctuations in flow before they become problems.

| Specific Parameters | Value / Description |
| Measurement Principle | The electronic turbine flow sensor operates based on turbine measurement. When the fluid passes through the sensor, it drives the turbine rotor. The rotation speed of the turbine is proportional to the flow rate. The built-in intelligent circuit processes the signal and provides various outputs, including switch, analog, pulse and RS485 communication, achieving accurate flow monitoring and control. |
