0B0B0B0PART 1 INTRODUCTIONS
6B6B6B6B1.1 PRINCIPLE
The Doppler ultrasonic flow meter is designed to measure volumetric flow of liquid within closed
conduit, the pipe line must be filled full of liquids, there must be a certain amount of air bubbles or
suspended solids in liquid.
Transducers are clamp-on or hot-tapped probe types, user don’t need to shut down the pipe flow
when install the clamp-on transducers.
The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer, the
sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the
receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound
waves will be reflected at a frequency shifted (Doppler frequency) from the transmitted frequency.
The shift in frequency will be directly related to the speed of the moving particle or bubble. This
shift in frequency is interpreted by the instrument and converted to various user defined measuring
units.
Fig 1.1
There must be some particles large enough to cause longitudinal reflection – particles larger than
100 micron.
When install the transducers, the installation location must have enough straight pipe length
upstream and downstream. Commonly, the upstream needs 10D and downstream needs 5D straight
pipe length, where D is pipe diameter.

8B1.3 NOTES FOR APPLICATION
When installing transducers, it need enough straight pipe;
When straight pipe is not enough, by setting menu SERVICE, the flowmeter will still get high
accuracy, and obtain a more accurate reading. more details, please see 4.3.16 SERVICE mode;
The measured liquid must contain a certain amount of air bubbles or suspended solids. When the
liquid contains air bubbles too much or too big, the bubbles occupy a certain volume, and then
lead to larger flowmeter reading. In this case, it needs to recalibrate the flowmeter.
When installing clamp-on transducers, the pipe material should have a good acoustical
conductivity;
When the transducer need be installed underground, recommend the insertion type.

PART 2 TRANSMITTER MOUNTINGAND WIRING
10B8B8B8B2.1 MOUNTING LOCATION
Mount the transmitter in a location that is:
zWhere little vibration exists
zProtected from falling corrosive fluids
zWithin ambient temperature limits -20 to +60°C
zOut of direct sunlight. Direct sunlight may increase transmitter temperature to above the
maximum limit

Please connect the Transducer A to Transmitter terminals “- +” TRANSMIT, red + to “+”, and black
“-” to “-”, and connect the Transducer B to terminals “- +” RECEIVE.
29B2.2.2 Power Supply Wiring Connections
For fixed flow meter, the power supply can be connected to 85-265VAC or 24VDC.
30B2.2.3 4-20mA Output
The 4-20mA Output interfaces with most recording and logging systems by transmitting an analog
current signal that is proportional to system flow rate.
The output load is up to 750 Ohms Max, internal power supply.

Please refer to 4.3.14 Dual Relay Configuration to see Menu Configuration.
The relay operations are user configured via the front panel to act in flow rate alarm or error alarm,
power supply interruption alarm and totalizer pulse. The relays are rated for 350VDC load voltage
and have a load current of 0.12A.
Fig 2.6A shows a wiring diagram for totalizer pulse output connection, the wiring terminal is
“PULSE -, +” in main board shown as Fig 2.3.

Fig 2.6B shows a wiring diagram for flow rate alarm, error alarm and transmitter power supply
interruption alarm output connections, the wiring terminal is “RELAY -, +” in main board shown as
Fig 2.5.
Note: Once the transmitter is powered on, the “RELAY -, +” output is normally closed state. The
transmitter power supply interruption alarm output is automatically output alarm, if the transmitter is
powered off, the “RELAY -, +” will automatically change normally closed state into normally open
state.

11B9B9B9B3.1 TRANSDUCER MOUNTING LOCATION
Placement of the ultrasonic transducer is the most critical step in achieving an accurate and reliable
flow reading. All flow meters of this type rely on a full-pipe of fluid that is flowing symmetrically
(evenly) in the pipe. Flow in partially filled pipes and immediately downstream of elbows, valves
and pumps are unstable and will lead to unstable readings and nonlinearity.
Select a transducer mounting location with adequate straight runs of pipe, both upstream and
downstream, to achieve stable readings. Examples of minimum upstream and downstream
requirements are included in Table 3.1
Table 3.1
The Doppler flow meter system will provide repeatable measurements on piping systems that do not
meet these requirements, but the accuracy may be influenced to various degrees.

12B10B10B10B3.2 TRANSDUCER INSTALLATION PROCEDURES
Locate the reference mounting positions of 3 and 9 o’clock (180° symmetrically) as shown in Fig 3.1.
Fig 3.1 Two transducers must be installed 180° symmetrically.
Two transducers called A and B transducer, A is transmitting transducer and B is receiving transducer,
they must be installed 180° symmetrically in order to have a more accurate measuring, shown as Fig
3.1.
All the transducers have a Serial Number corresponding to transmitter Serial Number.
13B11B11B11B3.3 TRANSDUCER CABLES
After the transducers A and B inserting into the pipe, the sensor cables should be routed to the
transmitter location. Verify that the supplied cable length is sufficient to meet the installation
requirements. While transducer cable extension is not generally recommended, if additional
transducer cable is required, utilize RG59 75 Ohm coaxial cable.
CAUTION: The cables are designed to carry low level signals that are developed by the sensor.
Care should be taken in routing the cables. Avoid running cables near sources of high voltage or
EMI/RFI. Also avoid routing the cables in cable tray configurations, unless the trays are specifically
used for other low voltage, low level signal cables.
14B12B12B12B3.4 COUPLANT
Assure an acoustically conductive path between the transducer face and the prepared piping surface,
a coupling compound is employed. Enclosed with the Doppler flow meter system is tube of Dow
Corning 111, silicone grease. This couplant is satisfactory for temporarily mounting the transducers
to the pipe. If the installation is long-term (more than a few days), we recommends utilizing a
silicone-based RTV such as Dow Corning RTV-732. If alternate couplant are utilized, the grease
chosen must berated to not flow at the temperature of the pipe.
Spread an even layer of coupling compound, approximately 1/8 inch [3mm] thick, to the prepared
transducer mounting areas of the pipe. Utilize Dow 111 for temporary mounting or Dow 732 for
permanent mounting.
