ULTRASONIC FLOW SENSOR
Application
The ultrasonic flow sensor can be used for flow measuring in local and district heating / cooling systems.
Features
- 1st approval in Europe for ultrasonic flow sensor with a 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
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 (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 -
