High long term stability, verified with independent AGFW test
Applicable for different calculators with impulse input
Free selectable impulse values, time continuously pulse, no puls packages
The temperature range depending on the applicaton 5 ... 150 °C
Battery or external power supply
Specific housing for falling and rising pipes

SHARKY FS 473

Application		Heating - cooling
Approval		MID and PTB K 7.2 for cooling
Ambient class		EN 1434 class C / MID class E2 + M2
Ambient temperature	°C	5 ... 55
Power supply		3.0 VDC battery - up to 12 years lifetime; external supply 3.0 ... 5.5 VDC
Mounting position		Any position
Protection class		Heating: IP 54; cooling: IP 65
Interfaces		Open Collector pulse output¹ - output for testing and communication²
Volume pulse value³		10 ml ... 5000 l/pulse (depending on sensor sizes and supply)
Cable length of impulse cable		10 m
Material of the flow sensor body		Brass (q_p 0.6 ... 10 m³/h), grey cast iron (q_p 15 ... 60 m³/h)

¹ The pulse output can be choosen without galvanic isolation (standard) or with galvanic isolation (only with battery supply). The flow sensor has by default a 4-wire impulse cable.
² The output for testing is a combined pulse output. The flow sensor can either emit a high resolution test pulse (standard) or communicate via the same output. By using an adapter the flow sensor can be read via the HYDRO-SET software.
³ The pulse duration is between 1 and 250 ms. It depends on the pulse value and on the nominal flow rate q_p.
Standard pulse values: 1, 2.5, 10, 25, 100, 250 l/pulse

Temperature range

Temperature range heating - battery supplied °C 5 ... 90 / 5 ... 105¹
Temperature range heating - external supplied °C 5 ... 130 / 150
Temperature range cooling - battery supplied °C 5 ... 90 / 5 ... 105¹
¹ Only in rising or falling pipes or tilted horizontal installation
