SECTION 1

INTRODUCTION

1.1 Product Description

1.2 Technology

The Drexelbrook Series 505-5100 Liquid Level Transmitter is an integral assembly which accurately measures continuous level up to a range of 80 feet, using ultrasonic technology.

The level measurement output is a 4-20 m

A Vdc signal.

The ultrasonic transducer does not contain moving components. It is not affected by electrical or physical parameters and has a wide range of temperature operation. The sensing element is made of CPVC for compatibility with a wide range of process materials.

Ultrasonic transmitters work on the principle of sending a pulsed, high-frequency sound wave from a peizo electric transducer to the contents of the vessel. The device measures the length of time it takes for the reflected sound wave to return to the transducer. A successful measurement depends on reflection from the process material in a straight line back to the transducer.

The two basic modes of operation are the “delta level” and

“delta distance.” In the delta level mode, the current output

(4-20 mA dc) increases as the liquid level rises. In the delta distance mode, the current output increases as the level falls

(distance to the transducer increases). The desired span range may be set from a minimum of 3 inches up to 80 feet.

To ignore obstructions in the vessel, Autoprofiling

TM tank mapping has been developed, which allows a “sonic snapshot” of an empty vessel. The transducer transmits a sound burst and the echo is recorded as a signature of the tank.

Any obstructions in the vessel will send an echo and create a profile. Later on, this signature or profile is locked into the ultrasonic unit’s memory so it will not respond to echoes created by these obstructions.

SECTION 2

INSTALLATION

2.1 Unpacking

Carefully remove the contents of the shipping carton and check each item against the packing list before destroying any packing material. If there is any shortage or damage, report it to the factory immediately.

2.2 Mounting

Transmitter

The 505-5100 Series ultrasonic transmitter is available with the electronic unit and transducer as either a single integral assembly or connected by 2 coaxial cables in the remote configuration. Extended sensing element lengths and special mountings can be provided to fit specific mounting applications. Refer to Figures 2-2 and 2-3 for standard mounting dimensions.

•••••

The 505-5100 Series transmitter is designed for field mounting, but it should be mounted in a location as free as possible from vibration, corrosive atmospheres, and any possibility of mechanical damage.

•••••

For convenience when adjusting, place the electronic unit in a reasonably accessible location. Ambient temperature should be between -40 o

F and 160 o

F (-40 o

C to 70 o

C).

•••••

The transducer axis must be mounted perpendicular to the liquid surface.

NOTICE

•••••

Ensure that the transducer face is not recessed into a mounting nozzle, as stray reflections can cause faulty operation.

NOTE

If the transducer must be mounted in a nozzle, use a

505-5110 High Discrimination unit.

•••••

When mounting the transducer, consideration must be given to the 30-inch Near Zone. If the level rises to within

30 inches of the sensing element face, a 4 or 20 mA signal

(20=level mode, 4=distance mode) will be generated; the

Near Zone LED will light; and the Near Zone Alarm Output will drop from 24 Vdc to 0 Vdc.

•••••

When mounting the transducer, consideration must be given to the beam angle of the acoustic signal. The typical conical beam angle of the acoustic signal is 12 degrees (6 degrees from center). Mount the transducer so that the beam does not hit the tank wall, ladder rungs, or other obstructions.

2.2 Mounting

Transmitter

(continued)

Application Example

Since the maximum distance that the 505-5100 ultrasonic transmitter can sense is 80 feet and the acoustic beam spreads out at a rate of 1.25 inches per foot, the transducer should be mounted 100 inches from the tank wall.

If it isn’t possible to mount the transducer the required distance from the tank wall and the acoustic beam does strike the side wall of the tank, then some acoustic energy will be lost. If the sidewall is relatively smooth, some signal loss can be tolerated; but any structure or 90 degree obstructions on the sidewall may be detected. See Figure 2-1.

CAUTION

If the Series 505-5100 is located in a hazardous environment, do not open enclosure cover or make/break any electrical connections without first disconnecting electrical power at the source. Ensure that wiring, electrical fittings and conduit connections conform to electrical codes for specific location and hazard level.

Indicators & Controls

Zero and Span Calibration Switches

(continued)

The zero and span are each set using three, ten-position rotary switches. Zero and span settings are made in inches with 1-inch resolution. Zero and span switches are used to calibrate the unit, discussed in Section 4.2.

LED Indicators

Two LED indicators are located on the transmitter to alert the user to a near zone or lost echo condition or improper calibration.

Calibration Pushbutton

The calibration pushbutton is used in conjunction with SW8 for maximum calibration accuracy. This button can also be used as a system reset.

Alarm Relays

Outputs (24 volts @ 35 mA) for near zone, lost echo and 2 alarm setpoints are provided to activate external relays or alarms. These are separate relay packages purchased as an option.

Step Gain Switch

Changes the gain of the ultrasonic transmitter to lessen any effect due to noise or obstruction. (Not available on High

3.2 Time Delay and

Repetition Rate

Certain applications may require a change of repetition rate and time delay.

•••••

Increasing time delay to either 15 or 45 seconds will smooth out a jumpy output signal caused by wave action or turbulence in the tank.

•••••

Changing the repetition rate is required any time that the tank roof is curved. A longer repetition rate ensures that the transmitter is not affected by reflected sound waves from the curved roof.

•••••

A lengthened repetition rate also helps reduce loss of echo due to foam.

If your application is similar to one described above, change the time delay or repetition rate using a small screwdriver and switch SW4. Table 3-1 details the switch settings. Each setting controls both time delay and repetition rate.

A step gain switch is available on standard 505-5100 units.

The step gain switch can be used to decrease the acoustic signal and avoid noise interference.

For example, the standard chassis is capable of shooting to a distance of 80 feet. The extra power produced to shoot the 80foot signal might be too much and could possibly cause nuisance reflections from irregular sidewalls, tank obstructions, or agitator blades. By reducing the gain of the chassis using the step gain switch, the effect of nuisance reflections can be eliminated.

High Discrimination Units

High discrimination chassis (405-5110) contains an additional circuit that automatically reduces the effect of nuisance echos created when mounting the transducer in a nozzle. This circuit allows mounting the transducer inside a pipe up to 14 inches above the tank opening.

Also, the high discrimination circuit lessens any effect from agitator blades and/or small obstructions and reduces interference caused by electrical noise.

The high discrimination electronics unit should not be used in applications where foam is present.

SECTION 4

CALIBRATION

4.1 Introduction

The 505-5100 Series transmitters are set at the factory to operate, in most applications, with minimal calibration. However, it is still necessary to set the Zero and Span switches for your actual vessel. This procedure is outlined in Section 4.2.

Once this procedure is accomplished the level reading should be within approximately 1% accuracy of range.

4.2 Calibration

—Level Mode

Use this procedure to set the Zero and Span for the vessel.

Choose Level or Distance mode:

With the power off, verify that all four switches on SW8 are

DOWN (open). Refer to Figure 4-1.

Set the Zero calibration switches to equal the distance in inches from the transducer face down to the minimum level

(usually tank bottom–0% or 4 mA). Refer to the calibration example in Figure 4-2. For this example, the switches are set to 1-8-6 starting with the top switch.

Set the Span calibration switches to equal the distance in inches from the minimum level to the maximum level

100% point or 20 mA (e.g. 1-5-6 starting with top switch).

Span setting must be at least 30 inches less than zero setting

—Distance Mode

With the power off, verify SW8 is configured properly.

Switches 1-3 are DOWN (open) and switch 4 is UP (on).

See Figure 3-1.

Set the Zero calibration switches to equal the distance in inches from the sensing element face to the maximum level

(0% or 4 mA). Refer to the calibration example in Figure 4-2.

For this example, the switches are set to 0-3-0 starting with the top switch. Zero switches must not be set lower than

0-3-0.

Set the Span calibration switches to equal the distance in inches from the maximum level to the minimum level

100% or 20 mA (e.g. 1-5-6 starting with the top switch).

NOTICE

NOTE

The maximum level point must be at least 30 inches from the sensing element (near zone).

Apply power; the 4-20 mA should now represent the amount of material in the vessel to within approximately 1%.

4.3 Setpoint Calibration

(only for those units equipped with optional 24

Vdc outputs)

a. Refer to Figure 4-1 for location of alarm switches

(ALM1 and ALM2).

b. Alarm points are set directly in inches from the zero point.

Normally, 24 Vdc is present on the male pins J4-J7, measured from the pins to common. When a setpoint alarm is exceeded, the voltage drops to 0 Vdc.

In the calibration example of Figure 4-2, the low alarm point would be set 6 inches from the zero point or minimum level. Starting with the top switch of ALM1, the settings would be 0-0-6. The high alarm point is 6 inches from the maximum level, which is 156 inches in this example. Starting with the top switch of ALM2, the settings would be 1-5-0 (span — 6 inches).

c. Alarm settings ALM1 and ALM2 can be set to alarm at any point in the calibrated range.

d. Connections are made to the transmitter using female connectors to J4, J5, J6, J7 and common connection, as shown in Figure 4-3.

TROUBLESHOOTING

The 505-5100 Transmitter is designed to give years of unattended service. No periodic or scheduled maintenance is required.

5.1 Troubleshooting

Procedures

If a problem should occur with the operation of the transmitter, use the following procedure for troubleshooting.

a. Ensure wiring connections are correct.

b. If the liquid surface has severe turbulence in the area where the ultrasonic beam hits, consider setting SW4 to add 15 or 45 seconds damping to 4-20mA loop.

c. Any continuous ultrasonic transmitter signal/echo can be adversely affected by significant foam on the liquid level surface. If this condition exists, please consult the factory for further application review and advice.

d. Ensure that the transducer face is not recessed into a mounting nozzle, unless High Discrimination electronics are used. Spurious reflections from the nozzle openings into the vessel can cause faulty operation.

e. If attempts to locate the difficulty fail, notify the local factory representative, or call the factory toll-free at

1-800-527-6297. To aid in troubleshooting, please complete the information on Table 5-1 before calling the factory service department.
