2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements for its tasks:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Are authorized by the plant owner/operator.
‣Are familiar with federal/national regulations.
‣Before starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the application).
‣Follow instructions and comply with basic conditions.
2.2 Designated use
Application and media
The measuring device described in these Brief Operating Instructions is intended only for flow
measurement of gases.
The measuring device described in these Brief Operating Instructions is intended only for
concentration measurement of liquids.
Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.

Teqwave F/I Basic safety instructions
Endress+Hauser 7
Measuring devices for use in hazardous areas, in hygienic applications or where there is an
increased risk due to process pressure, are labeled accordingly on the nameplate.
To ensure that the measuring device remains in proper condition for the operation time:
‣Keep within the specified pressure and temperature range.
‣Only use the measuring device in full compliance with the data on the nameplate and the
general conditions listed in the Operating Instructions and supplementary documentation.
‣Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area (e.g. explosion protection, pressure vessel safety).
‣Use the measuring device only for media to which the process-wetted materials are
sufficiently resistant.
‣If the ambient temperature of the measuring device is outside the atmospheric
temperature, it is absolutely essential to comply with the relevant basic conditions as
specified in the device documentation.
‣Protect the measuring device permanently against corrosion from environmental
influences.
Incorrect use
Non-designated use can compromise safety. The manufacturer is not liable for damage caused
by improper or non-designated use.
LWARNING
Danger of breakage due to corrosive or abrasive fluids and ambient conditions!
‣Verify the compatibility of the process fluid with the sensor material.
‣Ensure the resistance of all fluid-wetted materials in the process.
‣Keep within the specified pressure and temperature range.
NOTICE
Verification for borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability as minute changes in the temperature, concentration or level of
contamination in the process can alter the corrosion resistance properties.
Residual risks
LWARNING
The electronics and the medium may cause the surfaces to heat up. This presents a burn
hazard!
‣For elevated fluid temperatures, ensure protection against contact to prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
For welding work on the piping:
‣Do not ground the welding unit via the measuring device.

Product description Teqwave F/I
8 Endress+Hauser
If working on and with the device with wet hands:
‣Due to the increased risk of electric shock, gloves must be worn.
2.4 Operational safety
Risk of injury!
‣Operate the device in proper technical condition and fail-safe condition only.
‣The operator is responsible for interference-free operation of the device.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet state-
of-the-art safety requirements, has been tested, and left the factory in a condition in which it
is safe to operate.
It meets general safety standards and legal requirements. It also complies with the EU
directives listed in the device-specific EU Declaration of Conformity. Endress+Hauser confirms
this by affixing the CE mark to the device.
2.6 IT security
Our warranty is valid only if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the settings.
IT security measures, which provide additional protection for the device and associated data
transfer, must be implemented by the operators themselves in line with their security
standards.
3 Product description
The measuring system consists of a sensor and a transmitter. The sensor and transmitter are
mounted in physically separate locations. A connecting cable with a push-pull connector
interconnects the sensor and transmitter.
3.1 Product design
Two sensor versions are available:
• "Teqwave F" sensor
• "Teqwave I" sensor
Two transmitter versions are available:
• Transmitter with a touchscreen
• Transmitter with LED status indication
The measuring system uses concentration apps, which are individually tailored to the
measurement task and encoded to work only with the serial number of a specific transmitter.

3.1.3 Concentration apps
A concentration app contains specific configurations for the measurement of a certain liquid
and, along with the measured sensor signals, is used as the basis for calculating the
concentration. Endress+Hauser provides a separate concentration app for every type of fluid.
The concentration app is a file with lmf format. A list of the available concentration apps is
provided in the Applicator .
If you require a concentration app that is not already listed in the Applicator, Endress+Hauser
requires a sample of the fluid to create the concentration app. Every transmitter can use a
maximum of 25 concentration apps.
Concentration apps are individually encoded to work only with the serial number of a specific
transmitter. The transmitter in service uses the serial number saved in the .lmf file to check
whether the concentration app has been specifically configured for use with this transmitter.
If this is not the case, it is not possible to add the concentration app.
The data sheet provided with the concentration app contains information about the fluid, the
permitted measuring ranges and the accuracy of the concentration measurement.

4.1.1 Mounting position
Mounting location
h
A0032998
 3 Mounting location
Ideally, the sensor should be installed in an ascending pipe, while ensuring a sufficient
distance is kept to the next pipe elbow: h ≥ 5 × DN.

Teqwave F/I Installation
Endress+Hauser 11
Orientation Teqwave I
A0035457
 4 Orientation of Teqwave I
Mount Teqwave I so that the active sensor area can be fully immersed in the measured liquid.
If installing the sensor in a pipe, make sure the sensor is aligned correctly to avoid irregular
flow to the sensor. Rotate the sensor so that the dot on the process connection is aligned with
the flow direction.
If installing the sensor in a horizontal position, make sure the sensor is aligned correctly to
avoid the buildup of deposits around the sensing element. Rotate the sensor so that the black
dot on the process connection points up or down.
NOTICE
Measurement result is not representative
Heterogeneous mixing of the fluid and irregular flow to the sensor can distort the
measurement results, which are only valid for the layer of liquid in which the sensor is
located.
‣Ensure the homogeneous mixing of the liquid and continuous flow of liquid to the sensor.
Inlet and outlet runs
Observe the following inlet and outlet runs to comply with accuracy specifications:
