Introduction

About the AiRanger SPL

Note:

The AiRanger SPL is to be used only in the manner outlined in this instruction manual.

This microprocessor based level monitor is designed specifically for bulk solids and liquid level measurement applications. A SPL level monitor, utilizing a single Milltronics ultrasonic transducer (ordered separately), accurately monitors vessel material level without material contact.

The

SPL

transmits electronic pulses to the ultrasonic transducer. The transducer converts the electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The SPL measures the time from the pulse emission, to receiving the reflection (echo) from the material. Using the time measured, the SPL calculates the distance from the transducer face to the material.

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 atmospheres other than air.

homogeneous

(consistent composition)

The SPL is capable of monitoring wheat in 60 m (200 ft) high silo's, acetone in 45 gallon barrels, or almost anything in between.

This material and measurement range versatility is accomplished by utilizing Milltronics patented Sonic Intelligence measurement reliability, regardless of changing conditions within the vessel monitored.

Page 10 AiRanger SPL PL-573

. Sonic Intelligence provides high

Page 11

By utilizing ultrasonic echo ranging principles with Sonic Intelligence and velocity compensation, the SPL provides outstanding measurement accuracy, usually within

0.25% of range.

The distance calculation may be converted to space, material level, material volume, or remaining vessel capacity. The Reading chosen (and operating data) is displayed on the

Liquid Crystal Display

(LCD).

The relays and mA output may be used as preset (or programmed as desired) to activate alarms and/or operate remote monitoring equipment and/or process control equipment.

Level System Synchronization

Avoid mounting the SPL near another ultrasonic level monitor. Likewise, when more than one monitor is installed within a single plant/facility, ensure the transducer cables of each system are run in separate grounded metal conduits. If this system separation is impractical, or despite separation efforts measurement difficulties are encountered, system synchronization may be required.

To synchronize the SPL with another SPL…

1. Mount the level monitors together in one cabinet.

2. Ensure the level monitors share a common power (mains) supply, and ground (earth).

3. Interconnect the SYNC terminals of the level monitors to be synchronized.

Note:

To synchronize the SPL with other Milltronics ultrasonic level monitors, contact Milltronics or your local distributor.

Programming

Operator programmable features are identified by a Point Number and Parameter Number. The Point Number refers to the Relay Number as identified by the Point Type indicators. Parameter Numbers have a preset Parameter Value for each Point Number.

Programming is accomplished by altering the preset Parameter Values as required to obtain the RUN mode operation desired. All operator programmable features are defined in the Quick Start Parameters, Application Parameters, and Enhancement Parameters sections of this instruction manual.

Display

In the program mode, the Point Type, Point Number, Parameter Number, and Parameter Value (as well as a variety of other programming information) may be viewed.

Note that many indicators are specific to certain programming conditions and therefore, all indicators are not displayed at any given time.

Profile Records (P330 to P337)

The following parameters are for authorized Milltronics service personnel or Instrumentation Technicians familiar with Milltronics echo processing techniques.

Use these features to record and save a total of up to 10 Echo profiles, initiated manually (P330), or automatically (P331 et al). See Scope displays (P810) for echo profile viewing hardware / software requirements.

If 10 Echo Profiles are already saved, addresses 1 through 10 are filled, the oldest automatically initiated record is overwritten. Manually initiated records are not automatically overwritten. All records are automatically deleted in the event of a power interruption.

When a record is displayed, results are based on current programming (which may have been altered since the record was saved). This permits the effect on the echo profile to be observed when changing an echo parameter.

Use this feature to stabilize the reported material level, due to material level fluctuations (such as a rippling or splashing liquid surface), within the Echo Lock Window (P713).

This value (in % of Span) is automatically altered when Measurement Response (P003) is altered. (See Technical Reference Measurement Response). The higher the value entered, the greater the fluctuation stabilized. (0 = off)

Values:

0 to 100

P711 Echo Lock

Enhancement Param.

Use this feature to select the measurement verification process.

This value is automatically altered when Material (P002) and/or Measurement Response (P003) is altered. (See Technical Reference Measurement Response).

When set for "maximum verification" or "material agitator", a new measurement outside of the Echo Lock Window (P713) must meet the sampling criterion (P712).

For "total lock", Echo Lock Window (P713) is preset to "0". The SPL continuously searches for the best echo according to the algorithm chosen (P820). If the selected echo is within the window, the window is then centered about the echo. If not, the window widens with each successive shot until the selected echo is within the window. The window then returns to its normal width.

When Echo Lock is turned "off" the SPL responds immediately to a new measurement as restricted by the Max Fill / Empty Rate (P700/P701), however measurement reliability is affected.

Values:

0 = off 1 = maximum verification 2 = material agitator 3 = total lock

P712 Echo Lock Sampling

The sampling criterion sets the number of consecutive echoes appearing above or below the echo currently locked onto, that must occur before the measurements are validated as the new reading (for Echo Lock P711 values: 1 or 2).

Page 63

e.g. : P711 = 2, material agitator

P712 = 5:2 A new reading will not be validated unless 5 consecutive measurements

higher or 2 consecutive measurements lower than the current readings occur.

Values:

x.y x= # of `above' echoes y = # of `below' echoes

Note:

Resetting P711 returns P712 to the respective preset values.

P713 Echo Lock Window

Use this feature to adjust the new measurement change permitted before Echo Lock is applied.

The Echo Lock Window is a "time window" (in msec) placed about the echo used to derive the Reading. When a new measurement falls within the window, the window is recentered and the new Reading is calculated. Otherwise, the new measurement is verified by Echo Lock (P711) before the SPL + updates the reading.

When "0" is entered (preset), the window is automatically calculated based on the Max Fill / Empty Rate ( P700 / P701). This calculation is automatically performed when Measurement Response (P003) is altered. See Technical Reference Measurement Response.

For slower Measurement Response (P003) values the calculated Echo Lock Window is narrow. For faster values the window becomes increasingly wider, (When "immediate" is selected the window is normally wide open).

P832 TVT Shaper Adjust

Use this feature to bias the shape of the TVT curve, in order to avoid it crossing false echoes from fixed objects.

Adjustment to this parameter is best done while viewing the echo profile on an oscilloscope (refer to P810). When using an oscilloscope, the Echo Lock Window display becomes the TVT Curve Pointer.

The TVT curve is divided into 40 breakpoints, accessible by enabling the point number as the breakpoint index field. Each breakpoint is normalized to a value of 0, as displayed in the parameter value field. By changing the breakpoint value, up or down, the intensity of the bias applied to that breakpoint of the curve is respectively changed. By changing the value of adjacent breakpoints, the effective bias to the shaper can be broadened to suit the desired correction. In the case of multiple false echoes, shaping can be applied along different points of the curve. Shaping should be applied sparingly in order to avoid missing the true echo.

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 next (if applicable) shot is fired. After all shots of the transmit pulse are fired, the resultant echoes are processed.

The transmit pulse shot number, frequency, duration, delay, and associated measurement range are defined by parameters P803 and P840 to P852.

True echo selection is achieved by establishing the criteria which a portion of the echo profile must meet to be considered the intended target).

Insignificant portions of the echo profile outside of the measurement range (Span P007 + Range Extension P801), below the TVT Curve (P830 to P835), and less than the Confidence Threshold (P804) and Short Shot Floor (P851) are automatically disregarded.

The remaining portions of the Echo Profile are evaluated using the Algorithm(s) (P820) and Short Shot Bias (P850) programmed. When a combination of Algorithms are used, the portion of the Echo Profile providing the best averaged Echo Confidence (P805), is selected as the true echo.

True echo verification is automatically achieved by comparing the position (relation in time after transmit) of the "new" echo to the previously accepted echo position.

(atmosphere) sound velocity (P653) is multiplied by the acoustic

transmission

Sound Velocity

The sound velocity of the transmission medium is affected by the type, temperature, and vapour pressure of the gas or vapour present. As preset, the SPL assumes the vessel atmosphere is air at 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.

Also, if the temperature varies between the transducer face and the object monitored, a TS-3 temperature sensor, mounted near the material surface (solids) or submerged (liquids), should be used in combination with the ultrasonic/temperature transducer. Then when Temp Source, (P660) is set for "both", the transducer and TS-3 temperature measurements are averaged.

Atmosphere composition other than air can pose a challenge for ultrasonic level measurement. However, excellent results may be obtained if the atmosphere is

homogeneous

by performing a Sound Velocity Calibration (P651).

(well mixed), at a fixed temperature, and consistent vapour pressure,

Page 88 AiRanger SPL PL-573

Page 89

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. If the sound velocity in two vessels is always similar, future calibrations may be performed on one of the vessels and the resultant Velocity (P653) entered directly for the other vessel.

If the sound velocity of a vessel atmosphere is found to be repeatable at specific temperatures, a chart or curve may be developed. Then, rather than performing a Sound Velocity Calibration each time the vessel temperature changes significantly, the anticipated Velocity (P653) may be entered directly.

Volume Calculation

The SPL provides a variety of volume calculation features (P050 to P055).

If the vessel to be monitored does not match any of the 8 preset Tank Shape calculations, a Universal Volume calculation may be used. Use the level/volume graph or chart provided by the vessel fabricator (or create one based on the vessel dimensions).

Technical Reference

From this graph, determine which Universal Volume calculation will provide the best results, and select the level vs volume breakpoints to be entered (32 max.). Generally, the more breakpoints entered, the greater the volume calculation accuracy.

Universal, Curved (P050 = 10)

This volume calculation creates a cubic spline approximation of the level/volume curve. This option provides best results if the curve is non-linear, and there are no sharp angles.

level

Select at least enough breakpoints from the curve to satisfy the following:

• 2 breakpoints very near the minimum level

• 1 breakpoint at the tangent points of each arc

• 1 breakpoint at each arc apex

• 2 breakpoints very near the maximum level

For combination curves, ensure at least 2 breakpoints are entered immediately before and after any sharp angle (as well as 1 breakpoint exactly at the angle) on the curve.

Measurement Response

The SPL Measurement Response (P003) to material level changes is designed to exceed the most demanding installation requirements.

If any of these parameters are independently altered, a Measurement Response parameter alteration automatically changes the independently altered value.

Note:

Slower Measurement Response provides greater measurement reliability. Faster independently set Max Fill/Empty Rates may be impeded by Echo Lock, Scan Delay and Shot Delay values.

The Measurement Response setting automatically adjusts various parameters affecting the SPL response to material level changes as in the table that follows.

Example 1 - Level Measurement

Material Level

This is the most common application of the SPL level monitor.

For this example we'll assume the following:

• one 30 m high cement silo is to be monitored.

• the maximum vessel filling rate is 0.08 m per minute.

• alarm indicators are required when the cement level exceeds 25 m or falls below 10

m. filling equipment is to be automatically deactivated at 27 m.

•

• in the event of a measurement difficulty, failsafe operation is to be activated in 2

minutes.

• if the difficulty doesn't subside, the filling process is to be stopped before a spill

occurs.

• an XLT-30 transducer is mounted with its face flush with the top of the vessel.

• a TS-3 temperature sensor is connected to the Temp Sensor terminals.

Technical Reference

With process control equipment disabled, enter the RUN mode to monitor system performance and alarm programming. Otherwise, perform a Reading Measurement simulation (P920).

When satisfied with system performance and programming:

• connect a high alarm indicator to Relay #1 (see P100 = 4).

connect a low alarm indicator to Relay #2.

•

connect a high high alarm indicator and filling equipment stop/start control to Relay #3.

•

connect a low low alarm indicator to Relay # 4.

•

(Note that relays are de-energized in "power off" and "alarm" conditions).

For cement applications (or any very dusty dry solids), measurement difficulties during vessel filling are common. For this example (assume the maximum filling rate), failsafe operates as follows.

e.g.

09:15 am Echo lost at 6.00 m, low alarm is still on, failsafe countdown begins. 09:17 am Failsafe activated, actual level = 6.16 m, reported level = 6.00 m. 09:57 am Low alarm off, actual level = 9.36 m, reported level = 10.00 m. 12:27 pm High alarm on, actual level = 21.36 m, reported level = 25.00 m. 12:47 pm Infeed stopped, actual level = 22.96 m, reported level = 27.00 m.

PL-573 AiRanger SPL Page 93

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.

Material Volume

To perform a volume conversion for the preceding example, we'll assume:

• the vessel is cylindrically shaped with a flat bottom.

Example 2 - Space Measurement

This mode of operation is commonly used when remaining vessel capacity is of more importance to the installation than the actual material level.

Space

For this example we'll assume the following:

• the vessel is a 3 ft diameter by 15 ft long cylinder (including the parabolic ends of 1.5

ft each). the maximum vessel filling rate is 1 ft per minute (slower at mid level).

•

• in the event of a measurement difficulty, failsafe operation is to be activated in 6

seconds.

• if the difficulty doesn't subside, the mA output must immediately assume 22.00 mA.

• an XCT-8 transducer is mounted in a standpipe so that the face is 18 in. above the

vessel top. a TS-3 temperature sensor is mounted in the vessel to monitor liquid temperature.

With process control equipment disabled, enter the RUN mode to monitor system performance and alarm programming. (A Reading Measurement simulation (P920) may be performed to verify mA output programming).

When satisfied with system performance and programming, connect the mA output to the Programmable Logic Controller (PLC).

Note that on "power off" the mA output drops to 0.00 mA. During a power interruption, the "last known" mA output value is maintained in memory for 1 hour minimum. If power is interrupted beyond 1 hour, on power resumption, the mA output immediately assumes the "new value".

Enter "5" for average XCT-8 and TS-3 temperatures.

Application Assistance

The preceding examples describe only two ways in which the SPL can be applied to process measurement requirements.

The SPL can be used to monitor almost any process (within the temperature, measurement range, and chemical immunity capabilities of the system) where a distance measurement or determination of presence vs. lack of presence of an object is desired.

Technical Reference

By thoroughly reviewing the Parameters sections, you may identify some interesting ways of using the SPL to monitor specific processes.

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.

If you encounter a difficulty applying the SPL to a process measurement requirement, or successfully apply the SPL to a "unique process" we may have never considered, contact Milltronics or your local distributor.

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.

Technical Reference

The SPL utilizes continuously transmitted at regular intervals (no poll is required) at 4800 baud. All data is transmitted in structured messages of ASCII characters consisting of 8 data bits, no parity, and 1 stop bit.

If Peripheral Communications (P740) is set for "formatted" messages, a comma is inserted between each message field (except immediately preceding the "End of Message" characters).
