I. Introduction
1. Preface
Welcome to BE6200 series ultrasonic flow meter. Please read this instruction manual thoroughly before
installation and operation.
BE6200 ultrasonic flow meter is a time-difference type ultrasonic flow meter, whose transducers are mounted by
being clamped to the external surface of a pipe. It measures clean, well-distributed flows of liquids in which the
content of suspended particles is minimal.
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
BE6200 ultrasonic flow meter is based on single-board technology featuring high accuracy, reliability and
repeatability.
Additional advantages:
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, relay output, etc.

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.
As per equation (1) and (2) above, the velocity of flow is
calculated as below;
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 BE6200
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.
Where
M - travel times
V - velocity
D - inner diameter of the pipe

II. Installation and Operation
The clamp-on type ultrasonic flow meter allows for the simplest and the easiest installation of all types of
flowmeters, 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 the M25 window. Then the machine searches for proper amplifier gain. After S1, S2, S3 and S4 steps,
the machine enters into the normal operation state.

5. Transducer Mounting Methods
Clamp-on Sensors
There are two 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 0.5~16” (15~400mm). 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 for >10”(250mm) pipes or 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 one the next page;

BE6200 Ultrasonic Flow Meter O&M Manual
Flomotion Systems, Inc ~ FlomotionSystems.com Page 17
(1) Signal Strength & Quality
The signal strength is indicated by a number between 0.00 ~ 99.9. 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 ~ 99.9. 0.00 indicates that the signal is at its lowest level
and 99.9 the highest. It should be at least 60.00 for normal operation.
(2) Total Travel Time and Delta Time
The measurement is taken based on the total travel time and the time difference. Under normal working
conditions the Delta time should not fluctuate beyond +-20%. If continuous violent fluctuation or fluctuations over
+- 20% occur stability has been compromised and adjustments must be made. Review and adjust the transducer
installation and the initial setup parameters M10 - M29.
(3) Time Rate (TOM/TOS* 100)
This is used to confirm whether the transducers are located with the correct interval. This should indicate 100
±3%.

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.
5. Install transducers in accordance with instructions in the manual and the appropriate installation
drawings.
6. Apply a 1/4” wide bead of couplant edge-to-edge down the
center of the emitting surface of the transducers.
7. Follow the instructions in the manual for installing the
transducers.
8. 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
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.
