PolluFlow^® Flow Sensor

Sensus 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.

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
• 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

Wide temperature range:

• PN16: 5 to 90 °C (short-term 105 °C)
• PN25: 5 to 130 °C (short-term 150 °C)
