Technical Datasheet
Diehl Sharky 775 Heat &
Cooling Meter
The SHARKY 775 is an ultrasonic compact energy meter for measuring energy consumption
in heating and cooling applications for billing purposes . It measures by transit time , so there
are no moving parts to wear , with low pressure loss , large metering dynamics , a low start
fl ow rate and insensitivity to suspended particles . It has extremely low power consumption
for a battery life of up to 16 years , an optional integrated radio and a modular design with
MBus , RS 232, RS 485, analogue 4 to 20 mA and pulse outputs .
Features :
MID approval with dynamic range up to
1:250 ( class 2, depends on size )
Sizes from DN 15 to DN 100, Qp 0.6 to 100
m ³ / h
Battery life of up to 16 years
Integrated radio option
Modular : MBus , RS 232, RS 485, 4 to 20
mA , pulse in and out
