    About this Manual It is essential that this manual be referred to for proper installation and operation of your MiniRanger Plus. As MiniRanger Plus requires an ultrasonic transducer to make a working system, refer to the associated transducer manual as well.

  • Page 6: About Miniranger Plus

    About MiniRanger Plus Note: The MiniRanger Plus is to be used only in the manner outlined in this instruction manual. MiniRanger Plus is a versatile material level monitoring instrument. Material level measurement is achieved using advanced sonic echo ranging techniques. The unit is complete with an integral multifunction liquid crystal display, a four button keypad and an integral junction box.

    Start Up General The MiniRanger Plus has two modes of operation: run and program. When the unit is powered, after installation procedures have been completed, it is programmed to start up in the run mode, to detect the distance from the transducer face to the target in meters.

  • Page 33: Functional

    Functional Transceiver The MiniRanger Plus transceiver operates under 1 of 5 sets of preset conditions (P003), summarized as follows: parameter measurement echo f-s timer* long value response verification filter (P070) pulses* 0.1 m/min (slow) 1 m/min 10 m/min 102 m/min / 1.7 m/sec 1020 m/min / 17 m/sec (fast) *each measurement consists of one short pulse plus the set number of long pulses.

  • Page 34: Sound Velocity

    The basis is to physically measure the level (measuring tape or sight glass) and enter the value via P651. The MiniRanger Plus then calculates the sound velocity by comparing the entered physical measurement to its own ultrasonic measurement.

  • Page 35: Loss Of Echo

    Loss of Echo A loss of echo occurs when the MiniRanger Plus deems that the calculated measurement is unreliable, i.e. the echo confidence (P805) is less than the threshold (P804). This can be due to such circumstances as high level of electrical noise, poor grounding or poor transducer aiming.

  • Page 36: Relays

    Relays General Two onboard relays are provided in the MiniRanger Plus. Each relay can be assigned one of two functions: Alarm or Pump. Relay two can also be used to control a totalizer when the unit is in OCM mode.
  • Page 37 The MiniRanger Plus can convert a head measurement into a flow rate using a nine breakpoint head vs. flow characterisation curve; this chart is usually available from the manufacturer of the weir or flume or other primary measuring device (PMD).

  • Page 40: Ma Output

    Output The MiniRanger Plus can be programmed to provide an mA output (P200) of 0 to 20 or 4 to 20 mA, and for proportional or inverse span. Programming Upon entering the Program mode, the mA output level holds its prior value.

  • Page 41: Run / Program

    Run / Program When the MiniRanger Plus changes from run to program, the transceiver stops operating and the last measurement is stored; the associated reading, alarm status and mA output are held (pump control relays are turned off). As a courtesy, the unit reverts to the parameter last addressed during the previous program session.

  • Page 43: Applications

    Applications This section highlights the most common applications to which the MiniRanger Plus is likely to be applied. Other applications not described here, such as position monitoring of a piston on a wood pulverizer, are basically improvisational and imaginative ways of applying the MiniRanger Plus.

  • Page 44: Simple Level Application

    Simple Level Application One of the most common applications of a Milltronics process material level monitor is simple level measurement, whereby the material level or space between the transducer and reflecting surface is measured and displayed. This may or may not include alarms and mA output.

  • Page 48: High Level Switch

    High Level Switch The MiniRanger Plus can be programmed as a high level switch.

  • Page 50: Applications With Standpipe

    Applications with Standpipe In many liquid applications, access to the vessel must be made via a standpipe. In such cases, Milltronics can provide optional flanged transducers, or split flanges that mate to a flanged standpipe. Another option is to hang the transducer from a blind flange.
