Free selectable impulse values
The temperature range depending on the applicaton up to 5 ... 150 °C
Battery or external power supply
Specific housing for falling and rising pipes

SHARKY FS 473

Application		Heating - cooling
Approval		MID (DE-07-MI004-PTB022) and PTB K 7.2 for cooling (22.76/10.01)
Ambient class		EN 1434 class C / MID class E2 + M2
Ambient temperature	°C	5 ... 55 (<35 °C have a positive lifetime effect)
Battery 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; heating potted: IP 65; 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		2.4 m (4.9 or 9.9 m optional)
Material of the flow sensor body		Brass (q_p 0.6 ... 100 m³/h), spheroidal cast iron (q_p 15 ... 100 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 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
