Invasive Flowmeter

More About Invasive Flowmeter -

• Product Description -

  • Non-intrusive clamp-on ultrasonic flow measurement for liquids, eliminating the need for pipe cutting or modifications.
  • Integrated temperature sensors for accurate thermal energy calculation conforming to EN 1434 standards.
  • High accuracy and repeatability, capable of measuring very low flow velocities (down to 0.02 ft/s).
  • Maintenance-free operation with patented permanent coupling pads requiring no grease.
  • Wide application versatility: chiller plants, heating plants, HVAC systems, district energy, industrial cooling, and building optimization.
  • Supports continuous data logging with built-in storage (up to 2 years at 10-min intervals).
  • Communication options include analog outputs, RS485, Modbus RTU, Modbus TCP, BACnet IP, and more.
  • Calibration services available, supported by field experts and in-house calibration laboratories.
  • Suitable for LEED, Energy Star, and other energy certification requirements.
  • Robust design with permanent sensors suitable for extreme temperatures, up to 380°F (193°C).
