  • Page 27 FUNCTIONAL TRANSCEIVER The MultiRanger Plus transceiver will transmit via the transducer, a set of long and/or short pulses per measurement. The number and duration of the pulses is dependent upon P-88. A short pulse has a maximum measurement range of 2 m (6.6 ft) from the transducer face.
  • Page 28 TEMPERATURE COMPENSATION In order to provide compensation for uniform temperature variances of the sound medium, temperature compensation is provided. Temperature compensation consists of on board circuitry in the MultiRanger Plus and the integal (transducer) temperature sensor. The integral temperature sensor uses the transducer’s wiring and input terminals (TB1 - 8/9) to interface with the on board circuitry.
  • Page 29 P-63, velocity at 20 °C can be used to enter the known velocity at 20 °C of sound in a particular gas or vapour to view the resultant velocity of a sound velocity compensation, normalized to 20 °C. P-64, velocity at P-65, can be used to enter the known velocity of sound in a particular gas or vapour, or to view the resultant velocity of a sound velocity compensation, at the temperature of P-65.
  • Page 30 measurement’s reliability and accuracy. If it is found that false echoes are appearing ahead of the blanking zone, P-87 should be reduced accordingly. Blanking is automatically corrected for sound velocity change where temperature and velocity compensation is used, keeping the blanking at the distance at which it was entered.

  • Page 36 ANALOG OUTPUT The MultiRanger Plus can be programmed to provide analog output (P-6) of 0 or 4 - 20 mA, proportional or inverse span. The 4 and 20 mA levels can be trimmed slightly via P-97 and P-98 respectively to compensate for any offset between the MultiRanger Plus and the customer’s equipment.

  • Page 41 PUMP CONTROL APPLICATIONS The basic difference between a simple level application and a pump control application is that the relays assigned to pump functions are normally in a de-energized state and are energized when pumping is required. The MultiRanger Plus can be programmed to control up to 5 pumps. Each may be configured in one of the following ways.
  • Page 42 e.g. relays 1, 2 and 3 control three pumps by service ratio. It is required that pump 1 operate 60% of the time, pump 2 operate 10% of the time and pump 3 operate 30%of the time. » set the relay function : P-8, 11, 14 = dE : A9 »...

  • Page 47 PUMP TOTALIZER APPLICATION This type of application is an extension of the pump control application, accessed by setting P- 2 = 4. Unlike a pump application in which the mode of the measurement (P-2) can be of material or space, the pump volume totalizer mode is a measurement of the liquid volume pumped with reference to the material level.

  • Page 63 OCM APPLICATION This application is specific to monitoring the flowrate in one of the four following categories of primary measuring devices. Refer to the respective drawings at the end of this section for weir and flume outlines and transducer location. Single Exponential, these are flumes and weirs that can be characterized by a single exponential term ( P-40 = 1 )
  • Page 64 Flow readings are calculated by the MultiRanger Plus as a function of the head under the transducer, installed upstream from the primary measuring device ( P-40 ). The flows are then accumulated in the arbitrary volume units chosen per the time units of P-41 in an 8 digit totalizer.
  • Page 65 In the program mode, the high and low totals can be viewed or preset to any value by P-54 and P-55 respectively. The flow readings ( high and low total ) may be scaled down by factors of 10 ( P-52 ) to slow down the totalizer’s rate of fill and its decimal point ( P-53 ) positioned for the resolution required.
  • Page 66 An important consideration in OCM applications is that many primary measuring devices have the potential of running dry. In such cases, it must be insured that the range extension ( P-87 ) is sufficient so that the floor of the channel or of the converging section of the flume can be read.

The display however, will show a typical value of 3490. The value can be increased or decreased by pressing respectively or by entering a value.
  • Page 105 TROUBLESHOOTING GENERAL There are a few adjustments for echo processing and they should be used judiciously. Transducer location and aiming are the most important factors affecting the reliability of the MultiRanger Plus . Location and aiming of the transducer may be optimized by pressing to view the confidence level while in the RUN mode.

  • Page 111 MAINTENANCE The MultiRanger Plus requires no maintenance, however a program of periodic checks would be beneficial. The enclosure and circuit boards should be cleaned if necessary, but only when the power is disconnected at the main breaker and using a vacuum cleaner and a clean, dry paint brush.

Beam angle: angle between the opposing one-half power limits (–3 dB) of the sound beam Blanking: zone in which received echoes are ignored. Crest: the edge ( sharp-crested weir ) or surface ( broad crested weir ) over which the flow passes.

Subcritical flow: same as submerged flow. Submerged flow: when the downstream level rises or the discharge flow is so slow that it impedes the free flow of liquid through the primary measuring device.
