1 Measurement Principle

1.1 Principle

Ultrasonic pulses generated by the transducer (antenna) system which travel at the speed of sound
toward the target medium are reflected by the surface of medium and received by the transducer
system again. Due to the fact that the measurable time lapse between pulse emission and reception
by antenna is proportional to the distance between antenna and highest level of target medium, the
principle of ultrasonic level instrument can be illustrated as the following equation:

S=CxT /2, S: distance, C: velocity of sound, T: time lapse.

2 Product Overview

2.1 Features

• The advanced microprocessor and unique Echo Discovery processing technology, the ultrasonic

level instruments can be used under various complex conditions.

• The false echo storage function assures that the instrument can detect the right echo even with

the presence of multiple false echoes and present accurate measurement results eventually.

• The built-in temperature sensor inside the transducer can complete temperature compensation

for measurement results.

• Ultrasonic transducer has adopted patented sonic matching technology, which helps it strengthen

its emission power, enhance the signal intensity and eventually achieve accurate measurement.

3 Mounting Requirement

3.1 Basic Requirement for Installation

There is a certain existing beam angle while transducer radiating ultrasonic pulses. There should be
no barriers between the lower edge of transducer and surface of target medium. Therefore it is highly
recommended to avoid facilities inside vessels, such as ladders, limit switches, heating spirals, struts
and etc, during the mounting process. A false echo storage must be carried out during the installation
in this case. Furthermore, ultrasonic waves must not intersect the filling streams.
Be cautions during the installation when: the highest level of target medium must Not enter into
blanking zone; the instrument must keep certain distance to vessel walls; every possible measure
needs to be taken to position the instrument so that the direction of transducer emission is
perpendicular to the surface of measured medium.

3.1.1 Illustration

The lower edge of the probe is the reference plane for measurement.

1. Blanking Zone (menu 1 .9)

2. Empty (menu 1 .8)

3. Max. Adjustment (menu 1 .2)

4. Min. Adjustment (menu 1 .1)

Note: The highest level of measured medium must not enter into the blanking zone while ultrasonic
level instrument is in operation.

3.1.2 Mounting Position

Minimum distance of 0.65 ft between instrument and vessel wall must be assured while mounting
Tek-Sound 4200B-1 or Tek-Sound 4200B-2.

1. Reference Plane

2. Centre of Vessel or Symmetrical Axis

The best mounting position for a conical vessel with flat top is the centre of its top, as the
effective measurement can reach the bottom of the vessel.

3.1.3 Illustrative Diagram on Installation

1) Incorrect: Failure to turn the antenna perpendicular to the surface of the target medium.

2) Incorrect: Instruments are mounted in the center of concave or arched vessel tops,
which results in multiple echoes.

3) Correct

1) Incorrect: Mount the instrument in/above filling stream, which results in the measurement of
filling stream, not the target medium

2) Correct

Note: Sun shield or rain-proof is required for outdoor mounting

3.1.4 Moisture

In order to avoid Moisture under outdoor/indoor humid conditions or, instruments mounted
on cooling/heating vessels, the seal rings used on cables should be screwed tight. The cable must
also be bent downward outside the cable entry, indicated on the diagram below:

3.1.5 Socket

The transducer end must protrude at least 0.4 inches out of socket.

In case of strong reflective properties of target medium (Fig 1) and big socket diameter, you can mount
instruments on sockets higher than the antenna length. The recommended values for socket heights are shown
in the illustration below. The socket end should be smooth and burr-free, if possible also rounded.

Moreover, false echo storage must be carried out afterwards. On the contrary, if the reflective
properties of medium are weak (Fig 2), you are advised to heighten the mounting position of
instruments and also use a standpipe(optional) to reduce the influence caused by socket.

3.1.6 Agitator

If there are agitators in vessels, instrument must be mounted as far away from agitators as possible.
Once installation completed, a false echo storage should be carried out while agitators in motion to
eliminate negative influence caused by false echo of agitators. You are advised to opt for installation
with standpipe if foam or wave is generated due to the action of agitators.

3.1.7 Foam

Due to the action of filling, stirring or other processes inside vessels, dense foams are formed on the
surface of some liquid medium, which could attenuate emitting signals considerably. You are advised

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

to mount the instrument inside a standpipe or opt for a radar level instrument if the generation of
foam incurs measurement errors. Guided wave radar level instrument is the best option for similar
applications thanks to the fact that it is unaffected by foam generation.

3.1.8 Airflow

You are advised to mount the instrument inside a standpipe or opt for a low frequency radar level
instrument or radar level instrument with guided microwaves in the event of strong airflow presence
in vessels, e.g., outdoor installation with gusty wind or presence of vortex inside vessels.

3.1.9 Installation with Standpipe

1 Vent hole of diameter (0.19" to 0.39")
You are advised to opt for installation with standpipe (or bypass tube) to avoid the influence on
measurement caused by barriers inside vessels, foam generation or air vortex. If the measurement
is undertaken by Tek-Sound 4200B inside the standpipe the inner diameter of standpipe should be
at least bigger than the outside diameter of transducer. Please see Dimensional Drawings for actual
sizes. Avoid large cracks or welding seam when connecting standpipe. False echo storage must be
carried out as well in this case.

Note: You must NOT mount instrument inside standpipe while measuring adhesive medium.

4 Electrical Connections

4.1 Power Supply

4.1.1 20 mA/HART (2-Wire)

Power supply and current signal are carried by the same two-wire connection cable. See the
Technical Specifications of this guide for detailed requirement on power supply. A safety barrier
should be placed between power supply and instrument for intrinsically safe version.

4.2 Cable Connection

4.2.1 4-20mA/HART

Standard 2-wire cable, 18 to 22 Awg which assures the seal effect of cable entry, can be used as
feeder cable. You are recommended to use screened cables in the event of electromagnetic
Connection cable with special earth wire can be used as feeder cable.

4.2.2 Shielding & Grounding

The two ends of shielded cable must be connected with earth terminal. The shielded cable must be
connected with inner earth terminal directly inside the transducer, while the outside earth terminal
on housing must be connected with ground. In the event of earth-connected current, the shielding
side of shielded cable must be connected to ground potential via a ceramic capacitor (e.g. 1 µ F
1500V) in order to dampen the low

5 Adjustment Instructions

5.1 Adjustment Method

Three methods are available for Tek-Sound 4200B:

• Display/adjustment module

• Adjustment software

• HART handheld programmer

ViewPoint is a pluggable display/adjustment module. The adjustment can be done through operating
with four buttons on ViewPoint. Optional menu operation languages are available for selection.
ViewPoint is only used for display after adjustment in that the measurement results can be seen
clearly through the glass window.
