The Diehl Sharky 775 Compact Ultrasonic Thermal Energy Meter is a premier static ultrasonic heat and cooling meter engineered for district heating networks, residential sub-metering, and commercial boiler plant monitoring. Delivering exceptional dynamic rangeability and low pressure loss, the Sharky 775 combines precision transit-time acoustics with long-life battery power and seamless Open Metering System (OMS) radio integration.
Key Engineering Highlights:
- MID Approved (EN 1434 Class 2): Fully approved across complete dynamic measuring ranges up to 1:250 for heating, cooling, and combined duties.
- Static Acoustic Tube Design: High-purity ultrasonic transducers operate with zero mechanical parts, preventing obstruction and wear from system magnetite or scale.
- OMS Radio Telemetry Standard: Integrated Real Data Open Metering System (OMS) 868 MHz wireless transmission with AES-128 encryption.
- Removable Calculator Unit: 360° rotating multifunctional calculator can be detached and wall-mounted for convenient access in compact HIU cupboards.
- 16-Year Operating Lifetime: Advanced low-power microelectronics ensure up to 16 years of continuous maintenance-free battery operation.
