Ultrasonic Flow Sensor with Volume Pulse Output
The PolluFlow® ultrasonic flow sensor with volume pulse output has been designed for use with the PolluTherm® F Integrator for measuring heating and cooling energy. The measurement principle is based on the state-of-the-art ultrasonic technology.
Ultrasonic technology offers many benefits: no moving parts, low pressure loss, wide flow measurement range and sensitive to low flow, large metering dynamics, and insensitiveness to suspended particles.
Product Features
- External power supply (e.g. through the integrator)
- Standard pulsed output for the integrator
- Approval according MID Classe 2 with dynamic range 1:100 (qi:qp)
- No moving parts in the measuring channel
- Choice between horizontal, vertical and inclined installation
- Wide temperature range
- PN16: 5 to 90 °C (short-term 105 °C)
- PN25: 5 to 130 °C (short-term 150 °C)
- Ideally suited for e.g. “6 °C/12 °C” refrigeration systems with water as the medium
- Very good long term stability approved by AGFW duration test
- Extreme low energy consumption enabling a long lifetime
- 90 °C / PN16 with calculator PolluTherm® F
- 130 °C/PN16 with calculator PolluTherm® or PolluWatt Duo II
