S280T : Ultrasonic Heat Meter

Model : S280T


The S280T heat meter offers the most advanced BTU measurement by using state-of-the-art ultrasonic flow measurement technology. It does not have any moving parts that can wear out, thus, literally requires no maintenance. It is also very cost-effective. Both commercial and residential installations can profit from the advantages of the wear-free heat measurement, namely, precision, operation security and long service life. Omicron’s ultrasonic heat meter stands out among the competition due to its unique reflector-free sensor design. It is able to work reliably even when the water is dirty, which could be the case in the HVAC loop after many years’ operation. With 8 Digit LCD Display and tactile feedback membrane, the S280T can display instantaneous energy rate, total energy, temperature, temperature differential, flow rate, flow range, velocity, etc.

Features :
  • Wear-free ultrasonic measurement. No maintenance needed.
  • Proprietary robust sensor design. No reflector, thus, works reliably for both clear water and dirty water.
  • Excellent long-term stability. Accuracy does not degrade over time.
  • Not affected by magnetic interference.
  • Low pressure drop.
  • For both hot and cold water from -25°C to 95°C.
  • Free positioning for mounting.
  • Battery supply for 6 years.
  • Nominal pressure up to PN20.
  • Pulse / M-Bus / RS485 for remote readout.
  • Optional BACnet or M-Bus concentrator.
  • Optional AMR system solution, including meter reading software and utility billing software.
  • Easy to install. Electronic box can be detached from the sensor body and installed separately.
  • Low cost over the long run.
