PART-1 INTRODUCTION
1.1 GENERAL
It is the engineers and technicians' hope to measure the flow on the non-invasive pipeline
reliably. Series TF1100 are state-of–the-art universal transit-time ultrasonic flow meters, fit
to measure flow of full pipe line, providing a measuring system with unsurpassed accuracy,
versatility, ease of installation and dependability. Although designed primarily for cleaner
liquids, the flow meter is tolerant of liquids with the small amount of air bubbles or
suspended solids found in most industrial environments.
1.2 PRINCIPLE OF MEASUREMENT
The TF1100 ultrasonic flow meter is designed to measure the fluid velocity of liquid within
a closed pipe. The transducers are a non-invasive, clamp-on type, which will provide
benefits of non-fouling operation and easy installation.
The TF1100 transit time flow meter utilizes two transducers that function as both ultrasonic
transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a
specific distance from each other. The transducers can be mounted in V-method where the
sound transverses the pipe twice, or W-method where the sound transverses the pipe four
times, or in Z-method where the transducers are mounted on opposite sides of the pipe and
the sound crosses the pipe once. This selection of the mounting method depends on pipe
and liquid characteristics. The flow meter operates by alternately transmitting and
receiving a frequency modulated burst of sound energy between the two transducers and
measuring the transit time that it takes for sound to travel between the two transducers. The
difference between the transit-time is directly and exactly related to the velocity of the
liquid in the pipe, as shown in Figure 1.

When measuring temperature, the two temperature sensors of Pt1000 clamp on the pipeline
or insert in the pipe, and get two temperature values.
The value of energy is indicated / measured based on the following mathematical model:
Where: Q – Quantity of heat given up
V – Volume of liquid passed
k – Heat coefficient, is a function of the properties of the heat-conveying liquid at
the relevant temperatures and pressure
t1 – Inlet temperature of liquid
t2 – Outlet temperature of liquid

PART-2 TRANSDUCER INSTALLATION
2.1 GENERAL
The transducers that are utilized by the Series TF1100 contain piezoelectric crystals for
transmitting and receiving ultrasound signals through walls of liquid piping systems. The
transducers are relatively simple and straight-forward to install, but spacing and alignment
of the transducers is critical to the system's accuracy and performance. Extra care should be
taken to ensure that these instructions are carefully executed.
Mounting of the clamp-on ultrasonic transit time transducers is comprised of three steps:
Selection of the optimum location on a piping system.
Entering the necessary parameters into the TF1100 keypad.
(TF1100 will calculate proper transducer spacing based on these entries (menu 25))
Pipe preparation and transducer mounting.
2.2 MOUNTING LOCATION
The first step in the installation process is the selection of an optimum location for the flow
measurement to be made. For this to be done effectively, a basic knowledge of the piping
system and its plumbing is required.
An optimum location is defined as:
A piping system that is completely full of liquid when measurements are being taken.
The pipe may become completely empty during a process cycle - which will result in an
error code being displayed on the flow meter while the pipe is empty. Error codes will clear
automatically once the pipe refills with liquid. It is not recommended to mount the
transducers in an area where the pipe may become partially filled. Partially filled pipes will
cause erroneous and unpredictable operation of the meter.
A piping system that contains lengths of straight pipe such as those described in Table
2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal
and vertical orientation. The straight runs in Table 2.1 apply to liquid velocities that are
nominally 7 FPS [2.2 MPS]. As liquid velocity increases above this nominal rate, the
requirement for straight pipe increases proportionally.
Mount the transducers in an area where they will not be inadvertently bumped or
disturbed during normal operation.
Avoid installations on downward flowing pipes unless adequate downstream head
pressure is present to overcome cavitations in the pipe.

2.3 TRANSDUCER SPACING
TF1100 transducers are clamped on the outside of a closed pipe at a specific distance from
each other. The transducers can be mounted in V-mode where the sound transverses the
pipe two times, W-mode where the sound transverses the pipe four times, or in Z-mode
where the transducers are mounted on opposite sides of the pipe and the sound crosses the
pipe once. For further details, reference pictures located under Table 2.2. The appropriate
mounting configuration is based on pipe and liquid characteristics. Selection of the proper
transducer mounting method is not entirely predictable and many times is an iterative
process. Table 2.2 contains recommended mounting configurations for common
applications. These recommended configurations may need to be modified for specific
applications if such things as aeration, suspended solids or poor piping conditions are
present. W-mode provides the longest sound path length between the transducers - but the
weakest signal strength. Z-mode provides the strongest signal strength - but has the shortest
sound path length. On pipes smaller than 75 mm, it is desirable to have a longer sound
path length, so that the differential time can be measured more accurately.
