Diehl Metering SHARKY 774 Ultrasonic Heat Meter
Compact ultrasonic thermal energy metering for residential, apartment and light commercial heating and cooling applications.
The Diehl SHARKY 774 is a compact ultrasonic energy meter designed for applications where accurate thermal energy measurement, straightforward installation and remote-reading capability are required.
Ultrasonic measurement technology means there are no conventional moving mechanical measuring parts within the flow sensor, helping provide stable measurement performance over the operating life of the meter.
Available in 1/2" and 3/4" sizes, the SHARKY 774 is particularly well suited to apartments, residential developments, individual properties and smaller commercial heating or cooling systems.
Versions are available for heat-only or combined heat and cooling energy measurement, together with M-Bus or radio communication options for remote meter reading.

Heat & Cooling Energy Measurement
The SHARKY 774 can be supplied for conventional heat-energy measurement or for applications where both heating and cooling energy consumption need to be recorded.
This makes it suitable for modern building-services installations using systems such as heat pumps, communal heating networks and other applications where a single system may provide heating and cooling at different times of the year.
Ultrasonic Measurement Technology
The SHARKY 774 measures the flow of the heat-transfer medium electronically using ultrasonic signals rather than a conventional mechanical turbine or impeller.
With no moving mechanical measuring components to wear through normal operation, ultrasonic technology provides a reliable solution for long-term thermal energy measurement.
Remote-Reading Options
Communication options are available to allow the SHARKY 774 to be incorporated into automatic meter-reading and energy-monitoring systems.
- M-Bus – for wired meter-reading networks and building-management systems
- Radio – for wireless remote-reading applications where communication cabling is not required
Long-Life Battery Operation
The SHARKY 774 is designed around long-term battery operation, with a 16-year battery option available. This makes it particularly suitable for installations where a separate permanent electrical supply to the meter is undesirable.
Typical Applications
- Residential heat metering
- Apartment and flat energy sub-metering
- Communal heating systems
- Heat-interface applications
- Heat-pump installations
- Heating and cooling systems
- Light commercial energy metering
- M-Bus meter-reading networks
- Wireless remote-reading systems
Why Choose the SHARKY 774?
The SHARKY 774 is a strong choice where a compact ultrasonic heat meter is required for smaller pipe sizes. Its combination of ultrasonic measurement, heat and cooling capability, long battery life and M-Bus or radio remote reading makes it particularly suitable for residential and apartment energy-metering applications.
