Description

Ultrasonic Heat meter Pulsar is used for measurements: heat energy, cooling energy, heat power, flow rate, water temperature, temperature difference. It can be used in dead-end hot water supply system and measure water volume with temperature above set value. Heat meter consists of flow sensor, counter and 2 platinum temperature sensors. Heat meter’s counter calculates volume, temperature and heat energy consumption in flow and return pipelines.
  • Measures thermal energy consumption in heating and cooling systems
  • Compact dimensions
  • Removable calculator
  • High accuracy and durability
  • Insensitive against dirtt, no magnet inside hydraulic part
  • Self diagnostics
