Introduction

SITRANS LU01

Note:

• The SITRANS LU01 is to be used only in the manner outlined in this instruction manual.

• This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications.

The SITRANS LU01 is an ultrasonic long-range level monitoring system for liquids and solids. SITRANS LU01 level monitor uses one Siemens Milltronics ultrasonic transducers (ordered separately) to accurately monitor material levels without material contact.

The SITRANS LU01 transmits electronic pulses to each connected ultrasonic transducer. The transducer converts the electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The SITRANS LU01 measures the time from the pulse emission, to reception of the reflection (echo) from the material. Using the time measured, the SITRANS LU01 calculates the distance from the transducer face to the material.

The distance calculation depends upon the sound velocity within the vessel. When an Echomax transducer is used, variable air temperatures are automatically compensated. For superior air temperature compensation, a Siemens Milltronics TS-3 temperature sensor may be used for each vessel. A simple calibration feature compensates for homogeneous atmospheres other than air.

Introduction

1234

6078

The SITRANS LU01 uses Siemens Milltronics patented Sonic Intelligence®echo processing. Sonic Intelligence provides high measurement reliability, regardless of changing conditions within the vessel monitored. By using ultrasonic echo ranging principles with Sonic Intelligence and velocity compensation, the SITRANS LU01 provides outstanding measurement accuracy, usually within 0.25% of range.

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 1

The distance calculation can be converted to space, material level, material volume, or remaining vessel capacity. The reading chosen (and operating data) for each vessel is displayed on the LCD (liquid crystal display).

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

As preset, in the event of a measurement or technical difficulty, the SITRANS LU01 holds the Reading, Bar Graph, mA outputs, and relays at their last known values.

To operate process control equipment under these conditions, alter the following parameters as required.

P070 Failsafe Timer

The time for invalid measurements to elapse before Failsafe State activates.

Valu es

Altered by • P003 Maximum Process Speed Related •P129 Relay Failsafe

In the RUN mode, when a difficulty first occurs, the Reading, Bar Graph, relay status, and mA outputs are held at last known values and the Failsafe Timer is activated.

When a valid measurement is made before the timer expires, the SITRANS LU01 advances to the new material level (if changed) as normal (per Measurement Response, P003) and the timer resets.

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 37

Range: 0.0 to 9999 Preset 10.00 minutes

If the timer expires (before a valid measurement is made), the SITRANS LU01 advances to the Failsafe Material Level (P071) as restricted by Failsafe Advance (P072).

When a valid measurement is made after the timer expires, the SITRANS LU01 advances to the new material level (if changed), as restricted by Failsafe Advance (P072) and the timer resets.

Parameters

If the timer expires due to a measurement difficulty, LOE flashes in the Reading display.

Once activated, the Failsafe State initiates the following:

1. The material level is reported based on P071 Failsafe Material Level.

• The unit responds to the new level as programmed (control and alarm relays activate as defined by the programming).

• Individual relays can have independent failsafe responses. See

Failsafe

2. The appropriate error is displayed:

• LOE for loss of echo from the transducer

• Short for a shorted transducer cable

• Open for a cut transducer cable or a defective transducer

• Error for all other problems including reversed Ultrasonic/Temperature transducer terminal connections or wrong Transducer (P004) entered.

When modifying the preset value, set it short enough to protect the process but long enough to avoid false alarms. Only use No Delay (0.0 Minutes) for testing.

Relay reaction

The way in which relay programming reacts to the failsafe level depends on P129 Relay Failsafe (page 46). By default:

• Alarm relays have P129 = OFF and so react to the Failsafe Material Level.

• Control relays have P129 = dE and so de-energize the relay when the unit enters Failsafe mode regardless of the Failsafe Material Level.

Relays (P100 to P119)

The SITRANS LU01 has four relays (or digital outputs) used to control devices and alarms. While the number of devices is limited by the relays, all control functions are accessible through software and each parameter is indexed to the relays.

The SITRANS LU01 makes standard application programming easier by providing an extensive list of presets in P100 (Preset Applications).

Parameters

Standard alarms are set from P101 to P104. In the RUN mode, when the material level:

• rises to a High or High High Alarm value, the associated Alarm and Relay Status indicators are displayed and the allocated relay(s) de-energize.

• falls 5% of Span (P007) below the High or High High Alarm value, the associated Alarm and Relay Status indicators extinguish, and the allocated relay(s) energize.

• falls below the Low or Low Low Alarm value, the associated Alarm and Relay Status indicators are displayed and the allocated relay(s) de-energize.

• rises 5% of Span (P007) above the Low and Low Low Alarm value, the associated Alarm and Relay Status indicators extinguish, and the allocated relay(s) energize.

Note: Enter all standard alarm material level values in Units (P005) or percent of

Span (P007) as referenced to Empty (P006).

To display the current value (or enter a new value) in percent of Span, press required to display the % symbol.

Control functions allow each relay to be configured independently to take advantage of the SITRANS LU01’s advanced features and flexibility. Start with a preset application and then change the required parameters to make the task more efficient.

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 39

Setpoints are set up in P112 and P113. Each relay is triggered by one or more setpoints. The setpoints can be based on absolute level (P112, P113) or rate of change (P702, P703). Each control function specifies which setpoints are required.

P100 Preset Applications

Parameters

This parameter presets relays to operate as Standard Alarms. The Relay Allocation (relay/point number association) and Standard Alarm (P101 to P104) parameters are also preset.

Relay status during a measurement difficulty is dependent upon Failsafe programming. See Failsafe Parameters (P070 to P072) and Relay Failsafe (P129). As preset, relay status is held at last known material levels until a valid measurement is made.

Range Calibration (P650 to P654)

There are two types of calibration possible:

Offset: Adjusts the measurements by a fixed amount.

Sound Velocity: Adjusts speed of sound and changes the measurement calculations.

Do Offset calibration at any steady level unless a Sound Velocity calibration is also done. If both calibrations are done then do Offset at a known high level and Sound Velocity at a known low level.

P650 Offset Calibration

Calibrates Empty (P006) if the reported level is consistently high or low by a fixed amount.

If a material agitator (mixer) is used in the vessel monitored, set Echo Lock for maximum verification or material agitator to avoid agitator blade detection. Ensure the agitator is always ON while the SITRANS LU01 is monitoring the vessel to avoid stationary blade detection.

When set for max 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 zero 0. The SITRANS LU01 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 OFF , the SITRANS LU01 responds immediately to a new measurement as restricted by the Max Fill / Empty Rate (P700 / P701); however, measurement reliability is affected.

Parameters

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).

Primary Index Breakpoint

Valu es

Use this feature to bias the shape of the TVT curve to avoid selecting false echoes from fixed objects.

Adjust this parameter while viewing the echo profile with Dolphin Plus. Refer to the Dolphin Plus online help for details. If Dolphin Plus is not available, then an oscilloscope can be used. When using an oscilloscope, the Echo Lock Window display becomes the TVT Curve Pointer. See

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 SITRANS LU01 transmit pulse consists of one or more electrical shot pulses, which are supplied to the scanning relay. The scanning relay is activated as required, to supply the transmit pulse to the Transducer(s) connected to the SITRANS LU01 terminals.

The transducer fires an acoustic shot for each electrical pulse supplied. After each shot

echo

is fired, sufficient time is provided for 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.

Echo Processing

Echo processing consists of echo enhancement, true echo selection, and selected echo verification.

Echo Enhancement is achieved by filtering (P821 and P822) and reforming (P823) the echo profile (digitized signal representing the echo signal received).

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

(shot reflection) reception, before the next (if

Technical Reference

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 automatic. the position (relation in time after transmit) of the new echo is compared to that of the previously accepted echo. When the new echo is within the Echo Lock Window (P713), it is accepted and displays, outputs, and relays are updated as restricted by the Fuzz Filter (P710) and Rate Parameters (P700 to P703). If the new echo is outside of the Echo Lock Window, the new echo is not accepted until Echo Lock (P711) requirements are satisfied.

Distance Calculation

To calculate the transducer to material level (object) distance, the (atmosphere) sound velocity (P653) is multiplied by the acoustic transmission to reception time period. The result (round trip distance) is divided by 2.

Distance = Sound Velocity x Time

The Reading Value displayed is the result of performing any additional modification to the calculated distance (Operation P001, Units P005, Volume Conversion, P050 to P054, Reading Value, P060 to P063.)

transmission medium

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 SITRANS LU01 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).

Page 86 SITRANS LU01 – INSTRUCTION MANUAL 7ML19985BE02

Variable air temperature is automatically compensated when a Siemens Milltronics ultrasonic/temperature transducer is used. If the transducer(s) are exposed to direct sunlight, use a sun shield or a separate TS-3 temperature sensor.

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, at a fixed temperature, and consistent vapour pressure, by performing a Sound Velocity Calibration (P651).

The SITRANS LU01 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.

Technical Reference

Volume Calculation

The SITRANS LU01 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).

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, Linear (P050 = 9)

volume

level

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 87

This volume calculation creates a piece-wise linear approximation of the level/volume curve. This option provides best results if the curve has sharp angles joining relatively linear sections.

Enter a Level Breakpoint at each point where the level/volume curve bends sharply (2 minimum).

For combination curves (mostly linear but include 1 or more arcs), ensure numerous breakpoints are entered along the arc, for best 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.

Technical Reference

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.

Maximum Process Speed

The SITRANS LU01 Maximum Process Speed (P003) to material level changes is designed to exceed the most demanding installation requirements.

If any of these parameters are independently altered, a Max. Process speed parameter alteration automatically changes the independently altered value.

Note: Slower Max. Process Speed provides greater measurement reliability.

Faster independently set Max Fill/Empty Rates may be impeded by Echo Lock, Scan Delay and Shot Delay values.

However, by reviewing the example (or combination of examples) that matches your installation best, the relationship between SITRANS LU01 features and process measurement requirements may be more easily recognized.

Example # Description

1 Level (or Material Volume) Measurement for a single vessel.

2 Space (or Remaining Vessel Capacity) Measurement for a single vessel.

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 89

Example 1 - Level Measurement

Material Level

This is the most common application of the SITRANS LU01 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 1 terminals.

Technical Reference

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 coundown 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 am High alarm on, actual level = 21.36 m, reported level = 25.00 m.

12:47 am Infeed stopped, actual level = 22.96 m, reported level = 27.00 m.

7ML19985BE02 SITRANS LU01 – INSTRUCTION MANUAL Page 91

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.

• the vessel volume for Empty to 29.01 m (Span) is 1457 m3.

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).

• a mA output scaled from 4 mA at Full to 20 mA at Empty is required for PLC operation.

• 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 mA output 1 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.

The preceding examples describe only a few ways in which the SITRANS LU01 can be applied to process measurement requirements.

The SITRANS LU01 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.

By thoroughly reviewing the Parameters sections, you may identify some interesting ways of using the SITRANS LU01 to monitor specific processes.

Siemens 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.
