  • Page 3: Introduction

    Introduction INTRODUCTION The Flow-Alert flow meter combines the rugged proven technology of a direct reading, piston-type variable area flow meter, coupled with electrical contacts used to signal operators or PLCs at customer-defined flow rates This combination is sealed against industrial contamination by a NEMA 12 and 13 (IP52/54) rated enclosure (does not apply to strap versions) This product provides a local flow indication and automatically signals the operator or PLC if flow is too high or too low...

  • Page 4: Installation Recommendations

    Installation Installation Recommendations Hedland flow meters are designed for easy installation However, the following measures are recommended for reliable, trouble-free operation: • Piping should be accurately aligned and of correct length The high pressure body of the flow meter can withstand shock and flow/pressure pulsation Piping should be firmly supported by external mounting brackets, both upstream and downstream of the flow meter, to avoid any pipe flexing actions that could reduce flow meter life •...

  • Page 5: Installation Instructions

    Installation Installation Instructions 1 See Figure 1 Mount the flow meter so fluid is traveling in the direction of the flow arrow Figure 1: Flow direction arrows 2 See Figure 2 Select a mounting location that is suitable for viewing and product service To connect the flow meter into the piping system, place an open-ended wrench onto the flow meter wrench flats adjacent to the pipe connection being installed DO NOT wrench on the opposite end of the flow meter or leakage may result...

    Electrical Connections ELECTRICAL CONNECTIONS All Flow-Alert flow meters are offered with either single or dual switches Consult local wiring codes before applying power Wiring through Conduit Some installations may require a rigid conduit for the wiring To access a conduit connection: •...

  • Page 7: Reed Switch Configurations

    Electrical Connections Reed Switch Configurations Most units are equipped with an enclosure and a 15 ft (457 m) length of 4-wire #25 AWG type, PVC jacketed cable with a 4-pin Hirschmann connector Certain 1/4 in or SAE 6 meters with lower flow ranges are equipped with a strap housing For safe operation of the reed switch, do not exceed the maximum wattage for that switch For example, the normally open (NO) reed switch has a maximum power rating of 10 Watts If the switch is to operate at 24V DC, the maximum current is the wattage divided by...

  • Page 10: Maintenance

    Maintenance 6 Install the front cover and gasket To properly seat the cover gasket, tighten the cover screws in a crisscross pattern “Figure 6: Cover screw tightening sequence” on page MAINTENANCE Quick Recoupling The piston type variable area flow meter is inherently less sensitive to shock and vibration than other variable area designs The unique magnetic coupling also eliminates the need for mechanical linkages that can wear or loosen over the functional life of the flow meter However, a pressure spike or extreme flow surge can cause the piston to move at such rapid...
  • Page 11 Maintenance 2 Remove wiring, as needed, used for the flow switch(es) OTE: For configurations with an aluminum enclosure, wiring inside the enclosure does not need to be disconnected, unless additional cleaning is required Microswitch-equipped configurations may need to have wiring disconnected from the system to facilitate complete removal from the line Reed switch configurations have a Hirshmann connector that can be disconnected from the enclosure 3 Remove the flow meter from the line Remove excess piping from the flow meter...

  • Page 12: Application Information

    Application Information APPLICATION INFORMATION Liquid Viscosity Effect (SUS/cSt) The design uses a precision machined, sharp-edged orifice and biasing calibration spring that assures operating stability and accuracy over the wide viscosity range, common to many fluids High flow models of each flow meter size provide good accuracy over a viscosity range of 40…500 SUS (42…109 cSt) (specific gravity) Density Effect...

    Conversion Chart CONVERSION CHART The conversion chart provides a series of simplified mathematical formulas to adjust the graduated scale for changes in pressure (Table 5), temperature (Table 6), and/or specific gravity (Table OTE: Special scales can be made to accommodate other pressures, temperatures and specific gravity The conversion chart can also be used to adjust the multi-pressure flow scale to indicate flow rates in applications beyond the parameters stated on the scale...
