SHARKY FS 473

ULTRASONIC FLOW SENSOR

Application

SHARKY FS ultrasonic flow sensor is designed for flow measuring in local and district heating and heating/cooling systems. The ultrasonic technology used is based on the static measurement of the transit time and offers many benefits : no moving parts (prevents wear and tear of the metering components), low pressure loss, large metering dynamics and low start flowrate, resistance to suspended particles...

Features

Approval with dynamic range up to 1:250 (qi:qp) MID in class 2 (depending on meter size), standard 1:100
Complete range from DN 15 qp 0.6 m³/h up to DN 100 qp 100 m³/h
Available in threaded or flanged version
Heat-transfer fluid: glycol-free water
External power supply as standard or battery-driven as an alternative
Low power consumption ensuring optimum battery lifetime (up to 12 years)
Applicable for calculators with pulse input
Temperature range 5°C to 90°C / 5°C to 150°C

General

Application		Heating or bifunctional (heating/cooling) \| Heat-transfer fluid: glycol-free water
Approval		MID (DE-07-MI004-PTB022)
Ambient class		EN 1434 class C / MID class E2 + M2
Ambient temperature	°C	+5 ... +55
Power supply		External power supply: 3.0 ... 5.5 VDC \| Battery suply: 3.0 VDC (up to 12 years lifetime)
Mounting position		Any position
Protection class		Heating: IP 54; heating/cooling: IP 65
Interfaces		Open Collector pulse output¹ - output for testing and communication²
Volume pulse value³		10 ml ... 5,000 l/pulse (depending on sensor sizes and supply)
Pulse cable length		2.4 m (4.9 or 9.9 m optional)
Material of the flow sensor body		Brass (q_p 0.6 ... 10 m³/h), grey cast iron (q_p 15 ... 100 m³/h)

¹ The pulse output can be chosen without galvanic isolation (standard) or with galvanic isolation (only with battery supply). The flow sensor has by default a 4-wires pulse 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.
³ The pulse duration is between 1 and 250 ms depending on the pulse value and the nominal flow rate q_p.
Standard pulse values: 1, 10, 100 l/pulse (other pulse values available on request).
