  • Page 5: 1: General Description

    1: General Description Introduction This manual describes the operation of the Micronics Portaflow 220 portable flowmeter. The flowmeter is designed to work with clamp-on transducers to enable the flow of a liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts through the pipe wall or protrude into the flow system.

  • Page 6: Principles Of Operation

    1: General Description Principles of Operation When ultrasound is transmitted through a liquid the speed at which the sound travels through the liquid is accelerated slightly if it is transmitted in the same direction as the liquid flow and decelerated slightly if transmitted against it.

  • Page 7: Supplied Hardware

    1: General Description Supplied Hardware The Portaflow equipment is supplied in a rugged polypropylene carrying case fitted with a foam insert to give added protection for transportation. The supplied components are shown in Figure 1.2. Test Block Transducer Cables (x2) Chains (x2) Ultrasonic Couplant...

  • Page 8: Portaflow 220 Instrument

    1: General Description Portaflow 220 Instrument The Portaflow 220 is a microprocessor controlled instrument operated through a menu system using an inbuilt LCD display and keypad. It can be used to display the instantaneous fluid flow rate or velocity, together with totalised values.

    Micronics limited accepts no responsibility or liability if product has not been installed in accordance with the installation instructions applicable to the product.

  • Page 12: Transducer Attachment

    2: Installation Transducer Attachment The transducers are fitted to adjustable guide rails which are secured to the pipe using wrap-around chains and mechanically connected together by a steel separation bar. The separation bar also acts as a ruler to allow the distance between the transducers to be accurately set to the value determined by the Portaflow instrument.

  • Page 13: Fitting The Transducers

    2: Installation On each guide rail, attach one end of a securing chain to a hook on the tensioning bar (B), wrap the chain (G) around the pipe and then attach it to the hook on the other end of the tensioning bar whilst keeping the chain as tight as possible.

    3: Operating Procedures Instrument Calibration The Portaflow is fully calibrated before it leaves the factory; however the following adjustments are provided to allow you to further ‘fine tune’ your instrument to suit local conditions and application where necessary. Apart from the zero flow offset adjustment, these are normally carried out only where the instrument is to be used in a permanent or semi-permanent location.

  • Page 37 5: Troubleshooting Warning & Status Messages FLOW RATE ERRORS No flow signal Interpretation: This message appears when the transducers cannot send or receive signals to each other. Response: Firstly check that all cables are connected, transducers are on the pipe correctly with sufficient couplant on the face.
  • Page 38 5: Troubleshooting 4-20mA ERRORS Interpretation: The actual flow is higher than the maximum set on the mA range. mA out > Max Response: Re-scale the 4-20mA output to be able to cope with the higher flow – see page 25. NOTE: The 4-20mA output is calibrated before the instrument leaves the factory and Calibration 20mA Error!
  • Page 39 5: Troubleshooting BATTERY ERRORS Interpretation: The battery has discharged to below 30% remaining. This leaves the Battery Low instrument with approximately 4 hours remaining, depending on power usage, before it needs recharging. Response: Recharge the internal battery at the earliest opportunity. Do not leave the instrument for a prolonged period with a fully discharged battery.
