Sierra's Innova-Sonic® Model 205 thermal energy/BTU meter is a transit-time ultrasonic flowmeter designed to measure the thermal energy flow rate and totalized energy consumption in liquid heating and cooling applications. The unit features:

  • Non-intrusive clamp-on ultrasonic sensor technology.
  • Accuracy of ±0.5 percent of reading.
  • Built-in totalizers and data loggers.
  • Built-in SD card and a supplied data-analysis and graphing program.
  • Ultrasonic transducers, remote electronics, and two PT100 resistance temperature detectors.
  • Wide operating temperature range of –40°F to 340°F (–40°C to 170°C).
  • Bi-directional flow range of 0.0 to 40 fps liquids (0–12 mps).
  • Applicable pipe sizes from 1"-200" (25-mm-5000-mm).
