Battery calorimeter

AQ Calorimeter Kit – Smart Monitoring for Heat and Cooling Energy Meters (DN15–300) The AQ IoT Data Logger is perfectly suited for integration with calorimeters and flow meters used in district heating, cooling networks, or HVAC systems. Compatible with devices from DN15 to DN300, it offers reliable real-time monitoring and long-term data storage for energy consumption analysis. The logger supports bidirectional communication and can be configured locally via USB or Bluetooth (AQ Android App) or remotely through AQ WEB. It is battery-powered (2× D batteries) for more than 7 years, and can also be powered via mains or solar panels. Batteries are user-replaceable. Digital and analog inputs allow flexible connection to calorimeters, and optional relay outputs can control valves or switches. Additional antenna options improve signal performance in demanding environments. Pre-wired and pre-configured kits are available, including pressure and temperature sensors, ensuring quick installation in new or existing systems. The AQ platform also supports integration with existing calorimeters already in use. All data is logged internally with intervals from 0.01 seconds to 1 month, while transmission frequency is independently adjustable – from 1 minute to once per month. Default: log every 30 minutes, send twice daily. Communication options include LTE or NB-IoT, using standard AQ Protocol and MQTT, compatible with SCADA or third-party platforms. The AQ Calorimeter Kit provides an intelligent, open and reliable IoT solution for efficient heat and cooling energy monitoring.
