Heating

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

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

Multi-functionality

One sensor measures volume flow, temperature, pressure, heat quantity, glycol concentration, and air bubbles
Simplify your procurement and design with reduced complexity
