The MWA Technology team is proud to be a stockist of the SensoStar U ultrasonic heat meter from Engelmann Sensor GmbH. Our latest product spotlight focuses on this cutting-edge thermal energy meter that offers precision measurement and versatile communication options for a wide range of heating and cooling applications.
Ultrasonic technology
The SensoStar U uses ultrasonic time-of-flight measurement for accurate and reliable flow sensing. This non-intrusive method ensures long-term stability and minimal maintenance requirements.
High temperature resistance
This meter is suitable for district heating applications, with options for measurements up to 130°C (and brief exposure up to 150°C). Such high temperature tolerance makes the SensoStar U ideal for a wide range of industrial and commercial heating systems.
Dynamic temperature measurement
Temperatures are measured every 2 or 60 seconds by the SensoStar U, adapting to system needs. This dynamic approach ensures precise energy calculations while enhancing battery life.
Flexible installation
It can be installed in both outlet and inlet flow positions, with a detachable calculator unit for easy reading. The 85cm cable length (with a 2.85 metre option) allows for convenient mounting in tight spaces.
Multiple communication interfaces
Available with wireless M-Bus, M-Bus, pulse inputs/outputs, and LoRa options to fit various data collection needs, the versatility of the SensoStar U allows for seamless integration with existing building management systems and smart metering networks.
Comprehensive data logging
The meter stores 15 monthly and semi-monthly values, which are accessible via display or communication interfaces. It also records maximum values for flow, power, and temperatures, providing valuable insights into system performance.
Long battery life
With up to 10 years of operation on a single replaceable battery (6+1 years for some configurations), the extended lifespan of the SensoStar U reduces maintenance costs and ensures consistent operation over long periods.
Wide flow range
This meter is available in sizes from qp 0.6 m³/h to 10.0 m³/h, making it suitable for residential to light commercial applications. The SensoStar U’s broad range of flow rates allows it to meet diverse metering requirements across various project scales.
MID approved
The SensoStar U meets Class 2 accuracy standards under the Measuring Instruments Directive. This certification ensures the meter’s reliability for billing purposes and compliance with European regulations.
Cooling applications
Select models are also suitable for cooling energy metering (5-50°C range). This dual functionality makes the SensoStar U an excellent choice for buildings with both heating and cooling systems, simplifying metering infrastructure.
Enhancing connectivity with LoRa technology
For customers seeking advanced wireless connectivity, we are pleased to offer the SensoStar U with an integrated LoRa module. This cutting-edge addition enables the meter to transmit data over long distances using LoRaWAN networks, ideal for smart city and large-scale metering projects. The LoRa module boasts an impressive battery life of up to 11 years, ensuring long-term, maintenance-free operation. It supports both OTAA and ABP activation methods and operates in the 868 MHz frequency band with a powerful 14 dBm output.
Easy to configure via NFC using the Elvaco OTC app, this module makes the SensoStar U an even more versatile and future-proof choice for modern metering infrastructure. Whether you are managing a district heating system or a large commercial property, the LoRa-enabled SensoStar U provides the reliable, long-range communication you need for efficient energy management.
The SensoStar U is an excellent choice for energy managers, building operators, and utility companies looking for a reliable, high-performance heat meter. Its ability to detect backflow and air in the system, combined with its robust construction and flexible communication options, make it a versatile solution for modern heating and cooling systems.
MWA Technology is committed to providing customers with the latest in metering technology. The addition of the SensoStar U to our product lineup reinforces our position as a leading supplier of innovative measurement solutions.
