  • Page 5: Product Overview And Principle Of Operation

    Product Overview and Principle of Operation The FLR 1000 series of flow meters and sensors for liquids from Omega Engineering are capable of measuring flows as low as 13-100 ml/min or as high as 1.0-10.0 l/min. Highly repeatable results are achieved using a patented Pelton Turbine Wheel flow sensor design.

  • Page 6: Installation

    Do not exceed the pressure, temperature or power operating ranges detailed in the SPECIFICATIONS section of this manual. Omega Engineering shall not be liable for any damage or injury caused by incorrect operation of their products.

  • Page 7: Mounting The Flow Sensor Or Flow Meter

    (see section C2 for details of how to remove entrapped air or gas). Mounting the Flow Sensor or Flow Meter. The Omega Engineering FLR 1000 Series units have no particular installation requirements so may be mounted in any convenient position.

  • Page 8: Tubing Connections

    Only use the fittings factory installed on the unit. If the fittings are removed the calibration of the unit may be effected and leaking may occur. If different fittings are required please contact the Omega Engineering Service Department for assistance.

  • Page 9: Electrical Connections

    Overview The FLR 1000 series of flow sensors and flow meters provide a 0-5VDC, or 4-20mA, or 0-5VDC and pulse output proportional to the flow rate. This output may be connected to a display, data acquisition system or voltmeter / current meter.

  • Page 10: B) Connecting A Cable Assembly

    The FLR 1000-D, 1000-ST-D and 1000-BR-D series feature an integral display that provides a local flow reading. These units also have a 0-5VDC analog output available. If required, this may be connected to another display, data acquisition system or voltmeter.

  • Page 11: C) Electrical Connections - Voltage Output Units

    Electrical Connections – Voltage Output Units The cable assembly should be connected to the sensor as detailed in section 5(b) above. Power should not be applied to the sensor until all the connections have been made and checked. Electrical connections should be made as follows: Wiring Schematic For Voltage Output Units.

  • Page 12: D) Electrical Connections - Units With Both Voltage & Pulse Outputs

    Electrical Connections –Units with Both Voltage and Pulse Outputs The cable assembly should be connected to the sensor as detailed in section 5(b) above. Power should not be applied to the sensor until all the connections have been made and checked. Electrical connections should be made as follows: Wiring Schematic For Voltage and Pulse Output.

  • Page 13: E) Electrical Connections - Current Output Units ("I" Suffix)

    Electrical Connections – Current Output Units (“I” Suffix) The FLR 1000–ST-I provides a 4-20mA active current output proportional to the flow rate. The cable assembly should be connected to the sensor as detailed in section 5(b) above. Power should not be applied to the sensor until all the connections have been made and checked.

  • Page 14: F) Using A 0-5Vdc Output Power Adapter Package

    Using a 0-5VDC Output Power Adapter Package. An optional 0-5VDC Output Power Adapter Package is available for use with the FLR 1000 series (not the FLR 1000-ST-I). This consists of a power source (115VAC or 230VAC) and cable assembly with pig-tail (soldered wire) ends for the signal output.

  • Page 15: Operation

    Flow Readings The FLR 1000 Series provide a 0-5VDC, or 4-20mA (I suffix), or 0-5VDC and pulse output (P suffix) proportional to the flow rate. The type of output signal is detailed by the part number reference and on the calibration certificate.

  • Page 16: A) 0-5Vdc Analog Outputs

    0-5VDC Analog Outputs By monitoring the voltage output signal it is possible to determine the flow rate of the liquid. Units are configured so that an output signal of 5.0VDC is provided when the maximum flow (i.e. Full Scale flow) is passing through the unit.

  • Page 17: D) Units With An Integral Display

    200 ÷ (20-4) × 9 = 112.5ml/min Units With an Integral Display The FLR 1000-D, FLR 1000-BR-D and FLR 1000-ST-D series features an integral 3 ½ digit LCD display. This is configured to read in ml/min for flow ranges up to 50-500 ml/min and in l/min for flow ranges of 0.1 – 1.0 L/min.

  • Page 18: A) Flows Above The Maximum Rated Flow

    These methods should only be used to gain an indication of a sensor’s performance. Please contact the Omega Engineering Service Department if accurate, certified recalibration is required. A typical empirical calibration check may be carried out as follows: Carefully adjust the flow rate so that the maximum output signal is obtained.
  • Page 19 If there is a big difference in the percentage errors then the flow signal is no longer linear and the unit may be damaged (consult the Omega Engineering Service Department).

  • Page 20: Calibrating Units For Different Liquids

    Corrected flow rate = Uncorrected flow rate + error = 1.4 + 5% = 1.47 l/min Calibrating Units for Different Liquids The FLR 1000 Series will operate with most translucent liquids subject to compatibility of the wetted parts. Best results are obtained with low viscosity (less than 10 centistokes) liquids. For information regarding higher viscosity liquids, contact the Omega Engineering Service Department.

  • Page 21: Maintenance And Product Care

    If the unit appears to be malfunctioning please contact the Omega Engineering Service Department. The FLR 1000 Series of flow meters and sensors require no periodic maintenance if used within the recommended specifications. The next recommended recalibration date is stated on the calibration certificate supplied with the unit.
