- M-Bus or wireless M-Bus. In connection with Diehl Metering AMR systems technology, an unbeatable transmission performance is possible
- Constantly high measuring rate (flow: 2 s; temp.: 16 s) at up to 12 years battery life. The current output is calculated every 2 seconds
- AA batteries with low lithium content (0.7 g per piece) as A batteries
- Battery contacts corrosion protection, without spring contacts
- MID class 2 and PTB K7.2
- MID electromagnetic class E2 and mechanical class M2, which makes it less sensitive to sources of interference (e.g. frequency-controlled PWM pumps)
- Removable 8-digit LCD computer

Ultrasound compact energy counter SHARKY 774 COMPACT
The ultrasound compact energy counter can be used to record all data relevant to billing and measuring the energy consumption of heating and cooling systems. The measurement principle is static. The ultrasound measurement principle offers many advantages: No moving parts (less wear and tear and fouling of the counter), lower pressure loss, a high degree of dynamic measuring and a lower start-up value, resistant to loose parts.
