I. Introduction

1. Preface

Welcome to BE6000 series ultrasonic flow meter. Please read this instruction manual thoroughly before
installation and operation.

BE6000 ultrasonic flow meter is a time-difference type ultrasonic flow meter, whose transducers are mounted
clamped on pipe. It measures clean, well-distributed flows of liquids
those content of suspended particles is not very high.

The system is configured as below;

• Sensor Set: A pair of ultrasonic transducers mounted on the external surface on a pipe.

• Processor: The processor and the transducers are connected by two double shield high frequency

cables. The processor can be monitored and controlled remotely through a PC connected via
Internet. The following illustrates the configuration of the processor unit and the transducer sets;

2. Characteristics

BE6000 ultrasonic flow meter is based on single-board technology featuring high accuracy, reliability and
repeatability. The merits it provides above else are;

• Transducers are not intrusive. Therefore there’s no pressure drop. They are mounted on the outside
wall of the pipe.

• Advanced intelligent instrumentation, processing and printing (logging) according to user
requirements. Almost all common flow units are used. It uses normal power, built-in battery or DC
power, etc.

• It uses the most advanced direct time measurement method with the resolution of 0.2 ns. Coupled
with the advanced data processing functions, it provides high level of linearity.

• Various output options available including analog current output, frequency output, RS-232 serial
output, relay output, etc. The output options can be set by a menu or via a PC connected to the
processor through a RS-232C.

3. Operation Principle

This time-of-travel (transit-time) meter has a pair of transducers mounted on each side of the pipe. The
configuration is such that the sound waves traveling between the devices are at a 45- degree angle to the
direction of liquid flow. The speed of the sound signal traveling between the transducers increases or
decreases depending upon the direction of transmission and the velocity of the liquid being measured. A
time-differential relationship proportional to the flow can be obtained by transmitting the signal alternately in
both directions.

Where

M- travel times
D- inner diameter of the pipe
θ transmission angle

0- sound velocity in a static fluid

C

UP- upstream travel time (reverse flow

T

As per equation (1) and (2) above, the velocity of flow is
calculated as below;

direction)

DOWN- downstream travel

T
time(flow direction)
ΔT- difference of travel time between
downstream and upstream

The ultrasonic transit-time method is suitable for measuring single-phase, pure liquids without entrained air
bubbles. In industrial sites, the liquids may contain a certain level of impurities and flow conditions are often
not very uniform, thereby negatively affecting the performance of the ultrasonic flow meters. But our BE6000
ultrasonic flow meter adopts the most advanced direct time measuring method that considers the influence of
temperature and crude inside pipe situation in order to increase the accuracy and the reliability of the result.
With the use of the zero setting function, the meter renders 0.5% accuracy.

II. Installation and Operation

The clamp-on type ultrasonic flow meter allows for the simplest and the easiest installation of all types of flow
meters, though careful attention in selecting the measurement point, inputting pipe parameters, fixing the
transducers onto pipe, etc. in order to ensure accurate and reliable measurement of flow is needed. In this
chapter, you’ll be introduced to how to select the measurement point, input parameters, select mounting
method, etc.

1. Selecting the Measurement Point

Selecting the right measurement point is the most important factor for ensuring the accuracy and should be
done according to the following steps;

(1) Make sure the pipe to be measured is full.

(2) Select a location where it allows for straight pipe run of 10D upstream and 5D downstream. In case
there’s a pump or a bending section in the upstream, increase the upstream run to 30D in order to allow the
flow to fully develop into stable flow profile.

(3) Ensure the temperature at the measuring point is within the specified range.

(4) Avoid sections where the inner wall of the pipe is scaled or rusted that can negatively affect the
performance of the meter.

2. Setting the Parameters

In order to get the correct transducer mounting distance (the distance between the front edges of both
transducers), verify and set the following parameters;

(1) Pipe outer diameter
(2) Pipe inner diameter
(3) Pipe material
(4) Liner
(5) Fluid type
(6) Transducer type
(7) Transducer mounting method type

When the above parameters are properly set, the correct transducer mounting distance is calculated and
displayed in menu M25. Then the machine searches for proper amplifier gain. After S1, S2, S3 and S4 steps,
the machine enters into the normal operation state.

BE6000 Ultrasonic Flow Meter O&M Manual

6. Transducer Mounting Methods

Clamp-on Sensors

There are 2 mounting methods, ‘V’ and ‘Z’. Usually V method is used as standard because it provides longer
signal path and therefore more accurate measurement of flow velocity. It is recommended for pipes sizes
between 25~6000mm. Special attention should be given when mounting transducers to ensure that sensors
are aligned in direct line and along the center of the pipe and the transducer mounting line should be aligned.

Z method is recommended when the flow condition is bad because of scale built up inside the pipe,
entrained air bubbles, too thick liner, etc. which can induce a lot of noise into signal. Using this method, the
signal is dispersed in a straight path reducing the possibility of noise induction.

The user can verify whether the mounting is done correctly or not by checking the received signal strength,
total travel time, time difference and rate of travel time, which are described below;

14

Flomotion Systems, Inc. ~ FlomotionSystems.com

BE6000 Ultrasonic Flow Meter O&M Manual

(1) Signal Strength & Quality (M90)

The signal strength is indicated by a number between 0.00 ~ 9.99. 0.00 means no signal received and 99.9
means the signal strength is at the maximum. It should be larger than 60.0 for normal operation. The signal
quality Q is indicated by a number between 0.00 ~ 9.99. 0.00 indicates that the signal is at its lowest level
and 9.99 the highest. It should be at least 60.00 for normal operation.

(2) Total Travel Time and Time Difference (M93)

The measurement is taken based on the total travel time and the time difference. They are also indicative of
the condition of the installation of the transducers. Under normal condition, the time difference should be
smaller than 10%. If the pipe size is very small or the flow velocity is very low, the wave may be a little
bigger. When the wave is too big, so are the flow and the velocity. This is said to be of bad signal quality,
which may result from bad pipe condition, incorrect installation of the transducers or incorrect parameters
set.

(3) Time Rate (TOM/TOS* 100, M91)

This is used to confirm whether the transducers are located with the correct interval. This should indicate 100
±3%.

BE6000 Ultrasonic Flow Meter O&M Manual

6. Selecting a Location for Transducer Mounting

1. Locate the transducers downstream from the center of the longest available straight run. A location
ten pipe diameters or greater downstream from the nearest bend will provide the best flow profile
conditions.

2. Do not install the transducers downstream from a throttling valve, a mixing tank, the discharge of a
positive displacement pump or any other equipment that could possibly aerate the liquid. The best
location will be as free as possible from flow disturbances, vibration, sources of heat, noise, or
radiated energy.

3. Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale, rust,
loose paint etc., from the location. Do not mount the transducers on a surface aberration (e.g., pipe
seam, etc.).

4. Do not mount transducers from different ultrasonic flow meters on the same pipe. Also, do not run
the transducer cables in common bundles with cables from communication equipment, other
electronic systems or any type of ultrasonic equipment. You can run these cables through a common
conduit ONLY if they originate at the same flowmeter.

5. Never mount transducers under water, unless you order submersible units and you install them in
accordance with factory instructions.

6. Avoid mounting transducers on the top or bottom of a pipe. The ideal placement is either the nine
o’clock or three o’clock position for Reflect Mode, or one transducer at nine o’clock and the other at
three o’clock for Direct Mode. Mounting on a vertical pipe is recommended only if flow is in the
upward direction.

Preparing the Pipe Surface

1. Pick a mounting location with the longest straight run. You must have easy access to at least one
side of your pipe. The mounting location must remain full, even at zero flow.

2. Decide on your mounting mode (Z or V). Use V Mode whenever possible.

3. After receiving the spacing dimensions from the Installation Menu, prepare the pipe surface.
Degrease the surface, if necessary, and remove any grit, corrosion, rust, loose paint, etc. Use
abrasive material provided to create a clean contact surface for the transducers.

4. Refer to the next sections for illustrated instructions on how to locate each area to be cleaned and
how to use each mounting option.

Please note that the instructions show vertical mounting for clarity purposes only. Do not install
transducers on the top of a pipe. NOTE: In the following paragraphs, references to the 9 o’clock

position indicate the section of the pipe that is closest to you.

1. Install transducers in accordance with instructions in the manual and the appropriate installation
drawings.

2. Apply a 1/4” wide bead of couplant edge-to-edge down the
center of the emitting surface of the transducers.

3. Follow the instructions in the manual for installing the
transducers.

4. For permanent applications allow the RTV type couplant to
cure. It cures at room temperature upon exposure to
moisture in the air. During the cure, it releases acetic acid
(a vinegar like odor). It reaches full cure within 24 hours.

TRANSDUCERS

Apply 1/4” bead of couplant

to emitting surface.

• Low Flow Cutoff Value(M41)

Low Flow Cutoff Val.

0.01 m/s

Low Flow Cutoff is used to make the system display as “0” value at lower and smaller flows to avoid any

values of ±0.03 as “0”. Usually 0.03 is recommended in most applications.

• Set Zero(M42)

Set Zero[42

Press ENT to go

When the fluid is in the static state, the displayed value is called “Zero Point”. When “Zero Point” is not at
zero in the flowmeter, the difference is going to be added into the actual flow values and measurement
differences will occur in the flow meter.

Set Zero must be carried out after the transducers are installed and the flow inside the pipe is in the absolute
static state (no liquid movement in the pipe). Thus, the “Zero Point” resulting from different pipe mounting
locations and parameters can be eliminated. The measuring accuracy at low flow is enhanced consequently.

Press [ENT], wait for the processing instructions at the bottom right corner to reach 0. Set zero within the
existing flow may cause the flow to be displayed as “0”. If so, it can be recovered via M43.

BE6000 Ultrasonic Flow Meter O&M Manual

III. Trouble Shooting

With highly reliable design, the BE6000 ultrasonic flowmeter has a low failure rate. However, problems may
occur as a result of unskillful handling, setting errors or working in an extremely undesirable working
condition. For this reason, the meter is equipped with a self-diagnostic function. Problems detected are
displayed in time order in code form on the upper right corner of the LCT screen. Hardware malfunctions,
though generally checked after power is on, can also be detected (part of them) while the device is working
normally. Information about “stop working” problems caused by wrong settings or undesirable working
conditions can also be displayed, so users can locate the problems quickly and solve the problems according
to the solutions offered in the following two tables in time.

There are two kinds of error displayed in BE6000:

- Error messages are displayed during self-test after the power is switched on. After entering the
measurement mode, if there is an error, “*F” will be displayed at the top left corner of the screen. Check the
information being displayed and take specific steps according to the following tables. If problems persist,
contact your BE6000 distributor.

- Errors about the specific signal received or wrong settings can be displayed by the M08
window in error code form. Errors and solutions are listed in the following tables;

Error Code Causes and Solutions

Code Corresponding display M08 Causes Solution

*R System Normal System operates normally. Contact the manufacturer.

*J SCPU Fatal Error Hardware failure Contact the manufacturer.

*I Signal Not Detected

* No signal received * Make sure the sensor is

close to the pipe. Use
sufficient couplant.

* A poor contact between sensor
and the pipe, or too little couplant
applied.

* The sensor has not been installed
properly.
* Too much scale formation in the
inside wall.

* Make sure no rust, stain, no
oil paint on the pipe surface.
Use flat file clean to clean the
pipe surface.

* Check the original settings.

* You can clean the couplant
or change the pipe. But under
normal conditions, you can try
to change the measuring
point.

Low Signal Strength Poor Signal

*H

Quality

Current loop over 20mA (Ignore it
if the measuring process don’t use
current output)

*E

*F See above Table

Adjusting Gain=>S1 Adjusting
Gain=>S2 Adjusting Gain=>S3
Adjusting Gain=>S4 (Displayed in
M00, M01, M02, M03 windows)

*G

Empty pipe, M29 menu settings

*K

* New Liner * Wait until the liner is

saturated and solidified.

* Poor Signal Quality * The above
mentioned causes are applicable
here, too.

* 4-20mA current loop overflow over
120% * Wrong current loop output
settings

* Self-checking error * Restart the device and

* Perpetual hardware failure * Contact the company.
* These all 4 steps means that the
machine is going through the gain
adjustment process, preparing for
the normal measurement. If the
machine stops on S1 or S2, or
shifts between S1 and S2, it means
that the received signal is too low or
the waveform is not so good. The
reasons may include all the above­mentioned causes.
No liquid in the pipe or wrong
settings

* The same as above column

* Recheck the settings(see
M58 in the manual) or make
sure the actual flow is not too
big.

observe the information
displayed on the screen. If the
problem persists, contact the

company

If there is liquid in the pipe,
input “0” in the M29 menu.
