    The distance calculation is dependent upon the sound velocity within the vessel. When a Milltronics ultrasonic/temperature transducer is used, variable air temperatures are automatically compensated. For superior air temperature compensation, a Milltronics TS-3 temperature sensor may be used. A simple calibration feature compensates for homogeneous (consistent composition) atmospheres other than air.

  • Page 84 P922 Space Measurement The Reading corresponds to the distance between the material level and Span (P007). P923 Distance Measurement The Reading corresponds to the distance between the material level and the transducer face. P924 Volume Measurement The Reading corresponds to the volume calculation in percent of Max Volume (P051).

    Master Reset (P999) P999 Master Reset A Global Master Reset (reset all parameters to preset values) should be performed: • to clear all operator programming from memory. • after replacing the SPL EPROM with a different software revision number. Following a Global Master Reset, complete reprogramming is required. To perform a Global Master Reset: 1.

  • Page 87: Technical Reference

    Technical Reference Transmit Pulse The SPL transmit pulse consists of one or more electrical "shot" pulses, which are supplied to a transducer connected to the SPL terminals. The transducer fires an acoustic "shot" for each electrical pulse supplied. After each shot is fired, sufficient time is provided for echo (shot reflection) reception, before the next (if applicable) shot is fired.

  • Page 88: Distance Calculation

    20°C (68°F). Unless altered, the sound velocity used for the distance calculation is 344.1 m/s (1129 ft/s). Variable air temperature is automatically compensated when a Milltronics ultrasonic/temperature transducer is used. If the transducer is exposed to direct sunlight a TS-3 temperature sensor should be used.

  • Page 89: Volume Calculation

    The SPL automatic temperature compensation is based on the sound velocity/temperature characteristics of "air" and may not be suitable for the atmosphere present. If the atmosphere temperature is variable, frequent Sound Velocity Calibrations may be required to maintain optimum measurement accuracy. Sound Velocity calibration frequency may be determined with experience.

  • Page 94 When the dust settles (and the echo is regained) the reported level advances toward the actual level. When the reported level reaches 25.55 m (5% of Span less than the high high alarm trip point), the high high alarm goes off, restarting the infeed and filling the vessel to 27.00 m.

Milltronics has many years experience applying ultrasonic level measurement to a variety of processes in the mining, aggregate, lumber, grain, chemical, pulp and paper, water, and waste water industries.

  • Page 98: Communication Support

    Communication Support The SPL provides digital communication to a peripheral device, such as a computer or PLC, in one of three modes via the communication port, terminals 26 through 32. The mode of communication is established by the configuration of the connection made at the SPL, RS-232, RS-485 or bipolar current loop.

    Maintenance The SPL should require no maintenance or cleaning, though good housekeeping practices in and around the area of the enclosure are recommended. Wipe out the area of the enclosure lid docking bay recess with a clean dry cloth (if necessary) before installing the programmer.

  • Page 104: Measurement Difficulties

    Measurement Difficulties If a measurement difficulty occurs for greater than the Failsafe Timer (P070) setting, “LOE” is flashed alternately with the Reading display. Under certain conditions, a measurement difficulty may cause the SPL to “lock on” to a false echo and report a fixed or wrong reading.

  • Page 105: Fixed Reading

    If a discernible echo is observed (representative of the material/object surface), reduce the Confidence Threshold (P804) while taking new measurements (in the RUN or program mode). Sometimes, material simply cannot be detected during vessel filling. In these cases, set up failsafe operation such that the SPL "anticipates" the rate of material level increase and adjusts the reported Reading accordingly.

  • Page 106: Wrong Reading

    If the material monitored is a liquid, check for splashing in the vessel. Decrease Measurement Response (P003) as required to stabilize the Reading, or install a stilling well (contact Milltronics or your local distributor). Access the Noise (P807) parameter. If the peak value jumps wildly, verify the transducer cable shields are connected to the SPL shield terminals and not to ground elsewhere.
  • Page 107 Range (P852) to stabilize the "shot" mode used for the echo evaluation. Also, adjust the Short Shot Bias to increase (or decrease) the amount of preference given to short shot echoes over long shot echoes. Should a stable measurement still not be attainable, contact Milltronics or your local distributor. PL-573...
