SHARKY 774 Compact Heat Meter

The ultrasonic compact energy meter can be used for measuring the energy consumption in heating application for billing purposes. The measurement principle is static and based on the measurement of the transit time. Ultrasonic technology offers many benefits: no moving parts (avoids wear and tear of the metering components), low pressure loss, large metering dynamics and low start flow-rate, intensiveness to suspended particles.

Features & Benefits

  • AMR Smart Meter
  • M-Bus or wM-Bus Communication. Combined with Diehl Metering AMR System technology highest transmission performance is achievable
  • Constantly high measuring rates (vol.: 2s; temp.: 16s) with up to 12 years battery life time. Current power is calculated and updated every 2s.
  • AA-Cells contain less Lithium (0,7g per piece) than A-Cells. Not affected by dangerous goods transportation rules
  • Springless battery contact (hard-solder) is corrosion-protected
  • MID electromagnetic class E2 – less sensitive to neg. influence, e.g. culprit PWM pump
  • 8-digit LCD offers 3 fractional digits without risk of display overflow. Comfortable reading by removable calculator (0.45m coax cable)
  • Only 54 mm design height from pipe centre, hence easy to install in compact heat stations
