1. PRODUCT OVERVIEW
1.1 Introduction
The DCT7088 Digital Correlation Transit Time Flowmeter is a microprocessor-based instrument which
measures the flow of clean, homogeneous liquids (liquids without large concentrations of suspended
particles or gasses such as air bubbles). The flowmeter is noninvasive, which means that it measures flow
from outside the pipe. Its transducers can be mounted to a pipe within a matter of minutes, and flow
measurements may be made without interrupting the flow or modifying pipe work.
The DCT7088 can be configured using an integral keypad for entering variables such as pipe size, pipe
material, wall thickness, and fluid type (refer to Section 3, page 8).The flowmeter can also be remotely
configured and monitored via the RS232 interface mode using the D-Link data link utility (refer toAppendix
C, page 69).Another alternative to flowmeter configuration is to use the UltraScan utility which also
graphically analyzes the signal in a Microsoft®Windows®environment (UltraScan manual provided on
PolyCD).
1.2 Theory of Operation
Sound waves travel in fluids at a specific velocity depending on the type of fluid. If the fluid is moving, the
sound wave travels at a velocity equal to the sum of the speed of sound in the fluid and the velocity of the
fluid itself relative to the transducer.A sound wave traveling in the same direction as the fluid flow (down-
stream) will arrive sooner than a sound wave traveling against the flow (upstream).Atransit time flowmeter
operates by measuring both the absolute travel time of each sound wave and the difference in time
required for the waves to travel between an externally mounted downstream and upstream transducer
(Figure 1.2-A, below). Based on the transit time of the 2 sound waves, the flowmeter calculates the
average fluid velocity.
FIGURE 1.2-A: TYPICAL TRANSIT TIME SYSTEM
Once the differential transit time is calculated, several additional variables must be taken into consider-
ation. The overall velocity of the fluid is actually made up of many individual local velocities that vary
according to their distance from the pipe wall. The velocities in the center of the pipe are higher than the
velocities near the pipe wall. The combination of these individual velocities for a specific type of fluid within
a specific pipe yield a velocity distribution known as the flow profile (Figure 1.2-B, page 2), which is a
function of the Reynolds number. By properly configuring the flowmeter, the effects of the flow profile are
taken into consideration when calculating the mean fluid velocity. The flowmeter then multiplies this
velocity by the pipe’s cross-sectional area to obtain volumetric flow.

2
.....Theory of operation
FIGURE 1.2-B: FLOW PROFILES
1.3 Transit Time Accuracy
Noninvasive ultrasonic measurements are subject to a variety of effects that can influence measurement
accuracy.All ultrasonic instruments are velocity measuring devices and only infer volumetric flow from the
operator-entered parameter of pipe inside diameter (ID). When this value is squared to get cross-sectional
area, a 1% error yields a 2% error in volumetric flow. In practice, commercially fabricated pipe seldom has
ID consistency much tighter than 1%, and unless the pipe to be measured has been accurately measured,
this uncertainty is not reducible through instrument calibration.
The more sophisticated transit time flowmeters incorporate flow profile corrections to compensate for the
pipe’s cross-sectional velocity profile with a changing Reynolds number. However, this requires that the
operator knows the inside roughness of the pipe to be measured. The instrument may infer a roughness if
none is entered by the operator, but that is only an estimate based on the characteristics of new pipe.
Pipes can, of course, accumulate deposits which may not only reduce the ID, but affect the roughness as
well. Errors on the order of 2% as a result of this phenomenon are not uncommon.
While other factors may influence instrument accuracy to a lesser extent, the issues described above are
the major elements of pipe dependency upon absolute instrument accuracy. While calibration on a refer-
ence flow loop under known conditions is a useful exercise to determine the accuracy potential of an
instrument, it is not a guarantee of absolute accuracy on different pipes under field conditions.

2. WIRING THE CURRENT LOOP
The 4-20 mA current loop module has an input terminal and an output terminal. Both are indicated on a
label on the inside of the flowmeter door. The current loop output is rated for a loop resistance of up to 1 k
ohms and is isolated for up to 5 kV when loop-powered.
The 4-20 mA module is shipped with the current loop self-powered. Switch the module to loop power by
moving a jumper on the module. Current loop modules which are loop-powered must be driven from an
external power supply. In this case the flowmeter acts as a passive 2-wire transmitter.
Prevent possible electrical shock and/or damage to the meter – disconnect power
PRIOR to removing back cover of the breakout box and disconnect the breakout
box from the flowmeter and battery charger/AC adapter.
To connect the current loop:
1. Ensure the loop powering option is correct.
2. Locate the jumpers on the upper right corner of the module. Refer to Figure 2.1-A (below) to change
the jumper settings.
3. Refer to Figure 2.1-B (below) for the self-powered option or Figure 2.1-C (below) for the loop-powered
option.

The flowmeter does not use the new parameters until you access a primary
display.
3.5 Quick Setup Configuration
The Quick Setup procedure contains the minimal steps required for flowmeter configuration. These steps
enable the flowmeter to calculate transducer spacing, acquire ultrasonic signal, and measure flow. The
number in parentheses after the required menu is the 2-digit address to directly access that menu.
1. Select a proper transducer site according to Section 4 (page 33).
2. Access the Pipe submenu. This submenu contains setup menus related to the pipe parameters such
as pipe inside diameter (ID) and pipe outside diameter (OD).
Pipe Wall Thickness is an additional setup menu within the Pipe submenu. If
parameters for any 2 of the following 3 setup menus are entered, the flowmeter
calculates the remaining parameter automatically: Pipe OD (10), Pipe Wall
Thickness (11), Pipe ID (12).
Accuracy is directly affected by the square of an error in pipe dimensions; actual
measurements (not nominal) must be entered.
a. Select the PIPE OD menu (10). Figure 3.5-A(page 12) is displayed. Enter the value for the pipe
OD and press ENTER. Press the DOWN ARROW, and select Actual.
If you know the pipe circumference but not the OD, enter the circumference value
instead and press ENTER. Press the DOWN ARROW, and Figure 3.5-B (page 12)
is displayed. Select Circum. The flowmeter calculates the pipe OD automatically.

flow rate units. Volumetric units are displayed first, followed by the associated time per units.
a. Select one of the available volumetric units (Figure 3.5-K, below).
b. Press the DOWN ARROW and the time per unit options are displayed. Select the desired option
(Figure 3.5-L, below).
FIGURES 3.5-H THROUGH 3.5-L (LEFT TO RIGHT, TOP TO BOTTOM)
8. Install the transducers on the pipe using the spacing provided by the flowmeter, and connect the
transducer cables to the flowmeter.
9. Access a primary display (00 through 04) to complete the configuration process.
If the flowmeter and transducers are properly installed and a steady flow is present, the flow and signal
strength readings should be relatively stable.
If any of the above setup parameters are changed, the flowmeter stops measuring
flow until the new value is entered and a primary display is accessed to accept
the new value.
