Fully non-invasive (no drilling required) for measuring the flow rates of most liquids with gas/solid content less than 10% of volume, with 4 – 20 mA outputs and PT100 thermometer integration

Non-invasive (no drilling required) for measuring flow rates of most liquids with gas/solid content less than 10% of volume

  • OSCILLOSCOPE

Built-in signal oscilloscope for sensor positioning and diagnostics to achieve maximum accuracy with the measurement while providing visibility of the potential issues

  • COMMUNICATIONS

Connection to PC available as standard using both RS232 and built-in USB as well as 4 – 20 mA inputs which is available as an optional plug in

  • TOTAL FLOW

All measured values can be totalised giving total flow rate measured during a particular measuring session

  • RECOMMENDED APPLICATIONS

Commercial building heat metering, fuel montoring, waste water and many more

  • HEAT METERING

Ability to incorporate PT100 thermometer inputs so heat quantity measurement can be monitored alongside flow rate

KEY FEATURES:

  • VERSATILE:
    Capable of working on pipes DN15 – DN 2500; virtually any clean liquids; on a wide range of pipe materials. Without contact with the fluid, there are also fewer issues with the flowmeter being damaged by the nature of the fluid it is measuring compared to inline flowmeters
  • ACCURATE:
    Capable of measuring flow velocities between 0.01 m/s –
    25m/s. Resolution of 0.25mm/s
  • RELIABLE:
    Wall mounted and fixed therefore suitable for
    conducting measurements in a wide variety of poor conditions as the equipment is affixed firmly to the wall
  • LOW COST:
    No installation costs such as drilling into pipes, therefore no downtime to the pipe network is present. Only one individual is required to operate the instrument

KEY BENEFITS

  • ACCURATE: Accurate to +/- 0.5% under ideal conditions. Repeatability of 0.15% of measured value
  • MONITORING
    24/7 flow rate monitoring and alert is available
  • ROBUST
    Sensors rated IP66. Sensor temperature range -20°C to +150°C
  • INTUITIVE
    Unique Human Machine Interface (HMI) driven menu emphasises userfriendliness

Datalogging & Communications Ready

  • 16 MB datalogger included as standard – all measurement values can be logged
  • Serial Communications RS232 and USB included as standard, can be used for device control (command line interface) and datalogger download via PC
  • 4 – 20 mA, Digital, Modbus, Relay, OPTO, Open Collector Output available as optional plug-in modules

Optional Plug-in Modules

  • PT100 Thermometer Input (for heat metering applications)
  • 4 – 20 mA Current Input
  • 4 – 20 mA Current Output
  • Digital InputModbus RTU
  • Relay Output
  • OPTO Output
  • Open Collector Output
