FLOW SENSOR | ULTRASONIC

The ultrasonic flow sensor can be used for flow measuring in local and district heating / cooling systems.

  • Dynamic range (DR) of up to 1:250 (qi:qp) in class 2 (depends on meter size), standard 1:100
  • Extreme low power consumption --> longer battery lifetime
  • Approved according EN 1434 and MID in class 2 and 3 and PTB K 7.2 (cooling)
  • 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
  • General
    ApplicationHeating - cooling
    ApprovalMID (DE-07-MI004-PTB022) and PTB K 7.2 for cooling (22.76/10.01)
    Ambient classEN 1434 class C / MID class E2 + M2
    Ambient temperature°C5 ... 55
    Power supply3.0 VDC battery - up to 12 years lifetime; external supply 3.0 ... 5.5 VDC
    Mounting positionAny position
    Protection classHeating: IP 54; cooling: IP 65
    InterfacesOpen Collector pulse output1 - output for testing and communication2
    Volume pulse value310 ml ... 5000 l/pulse (depending on sensor sizes and supply)
    Cable length of impulse cable2.4 m (4.9 or 9.9 m optional)
    Material of the flow sensor bodyBrass (qp 0.6 ... 10 m³/h), grey cast iron (qp 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 qp.
    Standard pulse values: 1, 2.5, 10, 25, 100, 250 l/pulse
  • Temperature range
    Temperature range heating - battery supplied°C5 ... 90 / 5 ... 1051
    Temperature range heating - external supplied°C5 ... 130 / 150
    Temperature range cooling - battery supplied / external supplied°C5 ... 50
    1 Only in rising or falling pipes or tilted horizontal installation
