Heating, Heat Pumps & Boilers
Ultrasonic flow meters are essential for modern heat pumps and other heating technologies. They’re accurate, cost-efficient, robust, and feature state-of-the-art communication interfaces such as Modbus and LIN-Bus. They cause almost no pressure loss and include gas bubble and glycol compensation, revolutionizing flow measurement for heating applications.
APPLICATIONS
Heat pumps
Gas Boilers
Biomass Heating
Energy measurement
Heat energy measurement
- Use ultrasonic flow meters in both the source and heating circuit
- With an external temperature probe for the return flow, accurately measure heat energy in both circuits
- Monitor overall efficiency to optimize heat pump control effectively
- Maintain energy balance in geothermal heating sources
Gas bubble detection
R290 Heat pumps
- If the heat exchanger leaks, there’s a safety risk of flammable refrigerants (such as R290/Propane) entering the heating water circuit
- Ultrasonic Gas Bubble Detection identifies the refrigerant, enabling the initiation of a safety shutdown
Long-term usage
Energy efficiency
- The sensor is designed like a tube and causes almost no pressure loss
- No moving parts or bluff bodies
- Pump operates at optimal efficiency by accurately measuring volume flow
- Optimized refrigerant circuit due to precise measurement of heat energy consumption
- Increased modulation range through low flow measurement
Robust and reliable
- No moving parts mean no wear and blockage, ensuring a long service life without maintenance
- Sensor components don't touch the fluid directly, preventing measurement interference from dirt particles in the heating water
- Sensor ensures a minimum flow to initiate defrosting mode in air-to-air heat pumps
- Pressure, temperature, and flow measurement enable various predictive maintenance features
Glycol concentration detection
Glycol concentration detection and freezing-point estimation
-
Keep your end-user informed about the glycol concentration in their installation or the maximum negative temperature which the system can withstand
-
Real-time measurement of the glycol concentration in water-glycol mixtures
-
Selectable glycol type for accurate concentration results
All-in-one solution
