2Product Description
This section covers the reference and specification data, as well as ordering information.
2.1 Introduction
Tek-Clamp 1200A-100H Handheld Ultrasonic Flow Meter is a completely non-invasive
Ultrasonic Flow Meter. The flow meter uses the ultrasonic signal to measure the flow rates
with the transit time method. It consists of the built-in data logger for over 2000 lines of
data and is optional as an external data logger. Tek-Clamp 1200A-100H has a pair of
transducers capable of measuring flow rates in pipes from 1/2" (12.5 mm) to 28" (700 mm)
at temperatures of between 32 °F (0 °C) to 320 °F (160 °C). This flow meter can be virtually
applied to a wide range of measurements. A variety of liquid applications contain potable
water, cooling water, river water, raw sewage, reclaimed water, plant effluent, ultra-pure
liquids, chemicals.
2.2 Measuring Principle
When the ultrasonic wave is transmitted through the flowing liquid, the difference
between the upstream and downstream transit time (travel time or time of flight) can be
calculated, which is proportional to flow velocity.
Fig 1: Tek-Clamp 1200A-100H Handheld Ultrasonic Flow Meter
The Tek-Clamp 1200A-100H has been developed to measure the flow velocity of liquids in
pipes. The non-contact transducers/sensors are placed on the pipes and thus not subject
to wear and tear. The Tek-Clamp 1200A-100H works with two signal transducers (sensors)
that serve as ultrasonic transmitters and ultrasonic receivers. The sensors are installed on
the outer wall of the pipe at a defined distance, one below the other. The sensors can be
installed in Z shape (Z method). In this case, the ultrasound will pass through the pipe once.
The ultrasound will pass through the pipe four times if the sensors are installed in W shape
(W method). When using the Z method, the sensors are placed opposite to each other.

www.tek-trol.com 8
The sound passes through the pipe or liquid diagonally. The selection of the right method
depends on the characteristics of the liquid.

3Installation
This section covers instructions on installation and commissioning. Installation of the device
must be carried out by trained; qualified specialists authorized to perform such works.
CAUTION
•When removing the instrument from hazardous processes, avoid direct
contact with the fluid and the meter
•All installation must comply with local installation requirements and local
electrical code
3.1 Correct Mounting Point
The correct mounting point is a major factor for the installation of a flow Meter. Installation
at wrong point may influence measuring accuracy or flow meter service life, or even
damage the flow meter.
The axis for measuring electrode shall be approximate to horizontal direction.
Tek-Clamp 1200A-100H Handheld Ultrasonic Flow Meter can simplify the ultrasonic flow
meter installation process, by shortening installation time and improving installation
accuracy. Tek-Clamp 1200A-100H Handheld Ultrasonic Flow Meter installed by two
methods:
Fig 8: Tek-Clamp 1200A-100H Handheld Ultrasonic Flow Meter
3.1.1 Clamp on Transducer:
Install the Tek-Clamp 1200A - 100H Handheld Ultrasonic Flow Meter (with magnet) on
the pipe. It can help finish the flow measurement without any pressure drop. The need
for cutting the pipe is eliminated.

3.1.2 Clamp on mounting bracket transducer
•
•
•
3.2 Requirements for Measuring Flow meter Accuracy
•Medium must be conductive.
•The pipe should be completely filled with the medium.
•Medium conductivity should be homogeneous to avoid severe disruption. If chemical
substances need be injected into the pipe, the injection should be operated at upstream
side of flow meter.
•Magnetic flow meter system should be connected to the ground.
•There must be a straight pipe run no less than 5DN at flow meter upstream and 2DN at
flow meter downstream. (DN is the internal diameter of the pipeline).
•Do not install the flow meter near large electrical machine or transformer in order to
avoid the electromagnetic interference.
NOTE
Do not expose the electronic unit box to direct sunlight; in case of outdoor
installation, use a suitable protection shield.

3.3 Installation Condition
3.3.1 Sensors
3.3.1.1 Selection Of Sensor Position
The first step before installation should be finding a suitable position to place the
sensors. This is a requirement for accurate measurement results. Some basic knowledge
about the pipes / the plumbing system is necessary.
The ideal location would be an infinitely long, straight pipe, whereas there must be no
entrapped air (air bubbles) in the liquid. The pipes can either run vertically or
horizontally. A straight flow-calming section before and behind the measuring point
should be considered to avoid inaccuracies due to turbulence in the liquid. In general,
the section in front of the measuring point should be at least 10 x the pipe diameter,
and after the measuring point, it should be 5 x the pipe diameter.
The following chart shows examples of good positions:

www.tek-trol.com 16
The following should be considered when looking for a good measuring position:
1. Install the sensors on a preferably long, straight pipe filled with the liquid and
does not contain any air bubbles.
2. Make sure that the liquid and thus the pipe is not too hot for the sensors. The
temperature should be as similar to the room temperature as possible.
3. Consider fouling of the pipes. If possible, choose a clean or new pipe for
measurement. You can also clean the pipe. If this is not possible, consider the
thickness of the fouling as part of the liner.
4. Some pipes have a synthetic liner. There can be a boundary layer between the
outer pipe and the liner. This boundary layer can divert or weaken the ultrasonic
waves, which will make a measurement very difficult. If possible, these types of
pipes should be avoided. If this is not possible, sensors can also be built into the
pipe
3.3.1.2 Sensor Installation
The Tek-Clamp 1200A-100H has piezoelectric sensors which can transmit and receive
ultrasonic waves. The ultrasonic waves pass through the pipe walls, and the liquid
allows conclusions about the flow velocity. As the transit time of the ultrasonic pulses
is very short, the sensors should be installed as precisely as possible to ensure the
highest system accuracy.
Take the following steps to install the sensors:
•Some pipes have a plastic liner. There can be a boundary layer between the outer
diameter of the pipe and the inner liner. This boundary layer can divert or weaken
the ultrasonic waves. In this case, an accurate measurement will be very difficult. If
possible, these types of pipes should be avoided.
•Find an ideal position in the piping system, i.e., a straight section with new and clean
pipes, if possible.
•The pipes must be clean. Grind or polish the locations where you would like to place
the sensors.
•If pollution cannot be removed, its thickness should be considered part of the pipe's
liner.
•There must not be an air gap between the sensors and the surface of the pipe.
Attach the sensors using sufficient contact gel.
•Moreover, you should make sure there is no dust or sand between the pipe and the
sensor. To avoid air bubbles from causing measurement errors, place the sensors
on the pipe laterally.

www.tek-trol.com 17
3.3.1.3 Spacing Between the Sensors
The distance between the upstream and the downstream sensor can be seen in window
M25. The window states the inner distance between the two sensors, which you should
stick to as accurately as possible. The information in M25, however, must only be
considered a coarse adjustment. The fine adjustment is carried out by arranging the
spacing so that the time constant in M90 is exactly 100%.
To ensure accurate measurement values, the following data must be entered:
•The outer diameter of the pipe (M11)
•Material thickness of the pipe (M12)
•Material of the pipe (M14)
•The liner of the pipe (M16)
•Type of liquid (M20)
•Type of sensors connected (M23)
•The mounting method of sensors (M24)
•Check the spacing in window M25 and fix the sensors accordingly.
•During installation, ensure that the value of the time constant in M90 is 100 %,
that the signal strength is >700 and that the signal quality is >60.
3.3.2 Selection of Measurement Method
3.3.2.1 V-method Installation:
V-method installation is the most widely mode for daily measurement with pipe inner
diameters ranging from 15 mm to 400 mm (½" to 16”). It is also called reflective mode.
