Chapter 1. Introduction
1.2 Theory of Operation
1.2.1 Transit-Time Flow Measurement
In this method, two transducers serve as both ultrasonic signal generators and receivers. They are in acoustic
communication with each other; that is, the second transducer can receive ultrasonic signals transmitted by the first
transducer and vice versa.
In operation, each transducer functions as a transmitter, generating a certain number of acoustic pulses, and then as a
receiver for an identical number of pulses. The time interval between transmission and reception of the ultrasonic
signals is measured in both directions. When the liquid in the pipe is not flowing, the transit-time downstream equals
the transit-time upstream. When the liquid is flowing, the transit-time downstream is less than the transit-time
upstream.
The difference between the downstream and upstream transit times is proportional to the velocity of the flowing liquid
and its sign indicates the direction of flow.

2.4 Installing the Clamp-on Fixture And Transducer System
2.4.1 Clamp-on Fixture and Transducer Location
For a given fluid and pipe, the accuracy of AT600 depends on the location and alignment of the transducers. In addition
to accessibility, when planning for transducer location, adhere to the following guidelines:
• Locate the clamp-on fixture and transducer system so that there are at least 10 pipe diameters of straight,
undisturbed flow upstream and 5 pipe diameters of straight, undisturbed flow downstream from the measurement
point. Undisturbed flow means avoiding sources of turbulence in the fluid such as valves, flanges, expansions, and
elbows; avoiding swirl; and avoiding cavitation.
Figure 7: AT600 Transducer Location
• Locate the transducers on a common axial plane along the pipe. Locate the transducers on the side of the pipe,
rather than the top or bottom, since the top of the pipe tends to accumulate gas and the bottom tends to accumulate
sediment. Either condition will cause increased attenuation of the ultrasonic signal. There is no similar restriction
with vertical pipes as long as the flow of fluids is upward to prevent free falling of the fluid of a less than full pipe.

Chapter 2. Installation
2.4.2 Mounting Clamp-on Fixture Onto Pipe (AT6 Transducers)
The AT600 transducer system contains one clamp-on fixture, two transducers embedded inside the fixture and one
transducer cable. The transducer cable is already connected with the transducers and assembled with the fixture before
shipment as a default setup for easy customer installation.
The AT600 clamp-on fixture and transducer system can support pipe size ranges from 2 inch to 24 inch.The customer
can choose either dual traverse installation or single traverse installation for transducer mounting on the pipe.
As the maximum measurement range of one clamp-on fixture is 250mm, there are different kinds of installation
configurations based on the transducer spacing range and dual or single installation method. See Table 1 below for
rough estimates.
Table 1: Estimates for Pipe Configurations
Spacing Traverse Fixture Typical Pipe Sizes
0-250 4 1 2” to 4”
0-250 2 1 4” to 10”
0-250 1 2 10” to 20”
250-750 2 2 10” to 30”
250-750 1 2 20” to 30”
Please see section 3.7 (Sensor Setup) for determining transducer spacing. A two traverse installation is recommended
for most applications.
2.4.2a Dual Traverse Installation at Transducer Spacing Range 0 to 250mm
When the transducer spacing range is from 0 to 250mm, only one clamp-on fixture is needed for dual traverse
installation. See Figure 11 below for the dual traverse installation guide at transducer spacing range 0 to 250mm.
1. Install AT600 clamping fixture with transducers onto the pipe using the two mounting straps.
a. Choose location with enough straight run; refer to Figure 7 on page 7.
b. Install two straps onto the pipe with about 30 cm/1 ft apart.

Note: Two traverse (or two transducers in the same fixture) is the standard configuration. See the other configuration
method below for fixture assembly procedure.
Note: If there is a coating or protection layer on the pipe, remove the coating layer on the pipe at first by rasping to
expose the pipe material, where it is in contact with the transducer and couplant.
2.4.2b Dual Traverse Installation at Transducer Spacing Range 250 to 750mm
When transducer spacing range is from 250 to 750mm, another fixture is needed for larger transducer spacing; see
Figure 13 below for dual traverse installation guidance at transducer spacing range 250 to 750mm.
1. Install four straps onto the pipe with about 30 cm/1 ft apart from each other.
2. Put one clamp-on fixture with two transducers and one cable onto pipe and move straps onto sides of fixture,
then tighten screw on straps and validate strapping stays within sides of fixture.
3. Put the second blank clamp-on fixture onto the pipe and connect the two fixtures through the bar on left side of
the second fixture, then repeat step 2 to move the straps and tighten the second fixture.
Note: Be sure the bar on the left side of the second fixture is in close contact with the bar on the first fixture.

2.4.2c Single Traverse Installation at Transducer Spacing Range 0 to 250mm
When the transducer spacing range is from 0 to 250mm in a single traverse installation, two clamp-on fixtures are
needed for this installation. See the steps below for the single traverse installation guide.
1. Mark one straight line parallel with the pipe direction on the pipe surface, use a band tape to measure the
circumference of the pipe, and mark another two lines on position of +1/4 and -1/4 of circumference. This
creates two lines for two fixture alignment;
2. Install two straps onto the pipe with about 30 cm/1 ft apart from each other.
3. Put one clamp-on fixture embedded with two transducers and one cable onto the pipe and move the two straps
on two sides of the clamp-on fixture to catch the holder on the fixture, then put another blank fixture onto the
opposite side of the first fixture and hold it by the two straps,. Align the middle of the two fixtures with the red
straight line marked on the pipe surface in step 1.
Figure 18: Fixture Installation of Single Traverse at Transducer Spacing Range 0 to 250mm

Chapter 4. Error Codes and Troubleshooting
4.1 Error Display in the User Interface
The bottom line of the LCD displays a single, top priority error message during operation. This line, called the Error
Line, includes two parts: Error header and Error String. The Error header indicates the error pattern and error number,
while the Error string gives a detailed description of the error information.
4.1.1 Error Header
Error Pattern Error Header
Flow Error En (n is error number)
Device Error Dn (n is error number)
Warning Sn (n is error number)
4.1.2 Flow Error String
Flow errors are errors in the course of making a flow measurement. These errors can be caused by disturbances in the
fluid, such as excessive particles in the flow stream or extreme temperature gradients. The errors could also be caused
by an empty pipe or other such issue with the fluid itself. Flow errors are typically not caused by a malfunction of the
flow measurement device, but by an issue with the fluid itself.
4.1.2a E1: Low Signal
Problem: Poor ultrasonic signal strength or the signal exceeds the limit via the Program;
Cause: When SNR is less that the value of “Signal Low Limits” or the signal cannot be found when the flow is
started, the Low Signal error will occur. Poor signal strength may be caused by a defective cable, a flowcell
problem, a defective transducer or a problem in electronic console. A signal that exceeds the programmed
limits is probably caused by the entry of an improper value in the menu Program Advanced Error
Limits
Action: Check the components listed above (Refer to Diagnostics). Also check the inputted value in the menu

Chapter 4. Error Codes and Troubleshooting
4.2 Diagnostics
4.2.1 Introduction
This section explains how to troubleshoot the AT600 if problems arise with the electronics enclosure, the flowcell, or
the transducers. Indications of a possible problem include:
• Display of an error message on the LCD display screen, Vitality PC software, or HART.
• Erratic flow readings
• Readings of doubtful accuracy (i.e., readings that are not consistent with readings from another flow measuring
device connected to the same process).
If any of the above conditions occurs, proceed with the instructions presented in this chapter.
4.2.2 Flowcell Problems
If preliminary troubleshooting with the Error Code indicates a possible flowcell problem, proceed with this section.
Flowcell problems fall into two categories: fluid problems or pipe problems. Read the following sections carefully to
determine if the problem is indeed related to the flowcell. If the instructions in this section fail to resolve the problem,
contact GE for assistance.
4.2.2a Fluid Problems
Most fluid-related problems result from a failure to observe the flowmeter system installation instructions. Refer to
Chapter 2, Installation, to correct any installation problems.
If the physical installation of the system meets the recommended specifications, it is possible that the fluid itself may
be preventing accurate flow rate measurements. The fluid being measured must meet the following requirements:
1. The fluid must be homogeneous, single-phase, relatively clean and flowing steadily.
Although a low level of entrained particles may have little effect on the operation of the AT600, excessive amounts
of solid or gas particles will absorb or disperse the ultrasound signals. This interference with the ultrasound
transmissions through the fluid will cause inaccurate flow rate measurements. In addition, temperature gradients in
the fluid flow may result in erratic or inaccurate flow rate readings.
2. The fluid must not cavitate near the flowcell.
Fluids with a high vapor pressure may cavitate near or in the flowcell. This causes problems resulting from gas
bubbles in the fluid. Cavitation can usually be controlled through proper installation design.
3. The fluid must not excessively attenuate ultrasound signals.
Some fluids, particularly those that are very viscous, readily absorb ultrasound energy. In such a case, an error code
message will appear on the display screen to indicate that the ultrasonic signal strength is insufficient for reliable
measurements.
AT600 User’s Manual 75
Page 88
Chapter 4. Error Codes and Troubleshooting
4.2.2a Fluid Problems (cont)
4. The fluid sound speed must not vary excessively.
The AT600 will tolerate relatively large changes in the fluid sound speed, as may be caused by variations in fluid
composition and/or temperature. However, such changes must occur slowly. Rapid fluctuations in the fluid sound
speed, to a value that is considerably different from that programmed into the AT600, will result in erratic or
inaccurate flow rate readings. Refer to Chapter 3, Initial Setup and Programming, and make sure that the
appropriate sound speed is programmed into the meter.
4.2.2b Pipe Problems
Pipe-related problems may result either from a failure to observe the installation instructions, as described in Chapter 2,
or from improper programming of the meter. By far, the most common pipe problems are the following:
1. The collection of material at the transducer location(s).
Accumulated debris at the transducer location(s) will interfere with transmission of the ultrasound signals. As a
result, accurate flow rate measurements are not possible. Realignment of the flowcell or transducers often cures
such problems, and in some cases, transducers that protrude into the flow stream may be used. Refer to Chapter 2,
Installation, for more details on proper installation practices.
2. Inaccurate pipe measurements.
The accuracy of the flow rate measurements is no better than the accuracy of the programmed pipe dimensions. For
a flowcell supplied by GE, the correct data will be included in the documentation. For other flowcells, measure the
pipe wall thickness and diameter with the same accuracy desired in the flow rate readings. Also, check the pipe for
dents, eccentricity, weld deformity, straightness and other factors that may cause inaccurate readings. Refer to
Chapter 3, Initial Setup, for instructions on programming the pipe data.
In addition to the actual pipe dimensions, the path length (P) and the axial dimension (L), based on the actual
transducer mounting locations, must be accurately programmed into the flowmeter. For a GE Sensing flowcell, this
data will be included with the documentation for the system. If the transducers are mounted onto an existing pipe,
these dimensions must be precisely measured.
3. The inside of the pipe or flowcell must be relatively clean.
Excessive buildup of scale, rust or debris will interfere with flow measurement. Generally, a thin coating or a solid
well-adhered build up on the pipe wall will not cause problems. Loose scale and thick coatings (such as tar or oil)
will interfere with ultrasound transmission and may result in incorrect or unreliable measurements.
4.2.3 Transducer Problems
Ultrasonic transducers are rugged, reliable devices. However, they are subject to physical damage from mishandling
and chemical attack. The following list of potential problems is grouped according to transducer type. Contact GE if
you cannot solve a transducer-related problem.

Chapter 5. Communication
5.1 MODBUS
5.1.1 Introduction
In general, the AT600 flowmeter follows the standard MODBUS communications protocol defined by the reference
MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b. This specification is available at www.modbus.org
on the Internet. With this reference as a guide, an operator could use any MODBUS master to communicate with the
flowmeter.
Listed below are two limits of this implementation:
1. The AT600 supports only four of the standard function codes. These are Read Holding Registers (0x03), Read
Input Registers (0x04), Write Multiple Registers (0x10), and Read File Record (0x14).
2. The flowmeter needs a 15 ms gap between Modbus requests. The prime objective of the flowmeter is to measure
flow and drive the output, so the Modbus server has a low priority.
