2.2

Designated use

Application and media
The measuring device described in this manual is intended only for the flow measurement ofgases.
Depending on the version ordered, the measuring device can also measure potentiallyexplosive, flammable, poisonous and oxidizing media.
Measuring devices for use in hazardous areas or where there is an increased risk due toprocess 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 thegeneral 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 atmospherictemperature, 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.

4Storage and transport

4.1

Storage conditions

Storage and transport

Observe the following notes for storage:‣ Store in the original packaging to ensure protection from shock.
‣ Do not remove protective covers or protective caps installed on process connections. They
prevent mechanical damage to the sealing surfaces and contamination in the measuring
tube.
‣ Protect from direct sunlight to avoid unacceptably high surface temperatures.
‣ Select a storage location where moisture cannot collect in the measuring device as fungus
and bacteria infestation can damage the liner.
‣ Store in a dry and dust-free place.
‣ Do not store outdoors.

4.2

Transporting the productTransport the measuring device to the measuring point in the original packaging.

5Installation

5.1

Installation conditions• The recommended inlet and outlet specifications must be observed.
• The piping system and the device must be installed according to good engineering practice.
• Ensure the correct alignment and orientation of the sensor.
• Take measures to avoid or prevent condensation (e.g. condensation trap, thermal insulationetc.).
• Observe the maximum permissible ambient temperatures and medium temperature range.
• Install the measuring device in a shady location or use a weather protection cover.
• For mechanical reasons and to protect the pipe, support is recommended for heavy sensors .

Select inclined orientation (α = approx. 135°) for very wet or water-saturated gas (e.g. digester gas, undriedcompressed air), or if deposits or condensate are constantly present.

Pipes
The measuring device must be professionally installed, and the following points must be
observed:• Weld pipes professionally.
• Use seals of the correct size.
• Align flanges and seals correctly.

To ensure maximum measuring performance, choose an inlet pipe with an almost identicalinternal diameter.
Inlet and outlet runs
A fully developed flow profile is a requirement for optimal thermal flow measurement.
To achieve the best possible measuring performance, observe the following inlet and outlet
runs at the very minimum.
• In the case of bidirectional sensors, also observe the recommended inlet run in the opposite
direction.
• If several flow disturbances are present, use flow conditioners.
• Use flow conditioners if it is not possible to observe the required inlet runs.
• In the case of control valves, the amount of disturbance depends on the valve type andopening degree. The recommended inlet run for control valves is 50 × DN.
• In the case of very light gases (helium, hydrogen), the recommended inlet run must be
doubled.

Flow conditioner
Use flow conditioners if it is not possible to observe the required inlet runs. Flow conditioners
improve the flow profile and therefore reduce the necessary inlet runs.
The flow conditioner is permanently integrated in the flange and must be ordered withthe device. It is not possible to retrofit a flow conditioner.

Environment and process requirements

Ambient temperature range
Measuring device• –40 to +60 °C (–40 to +140 °F)• Order code for "Test, certificate", option JP:–50 to +60 °C (–58 to +140 °F)

Readability of the local
display–20 to +60 °C (–4 to +140 °F)
The readability of the display may be impaired at temperatures outside the temperature
range.

NOTICE
Danger of overheating‣ Ensure that the temperature at the lower end of the transmitter housing does not exceed
80 °C (176 °F).
‣ Ensure that sufficient convection takes place at the transmitter neck.
‣ When using in potentially explosive atmospheres, observe the information in the devicespecific Ex documentation. For detailed information on the temperature tables, see theseparate document entitled "Safety Instructions" (XA) for the device.
‣ Ensure that a sufficiently large area of the transmitter neck remains exposed. The
uncovered part serves as a radiator and protects the electronics from overheating andexcessive cooling.

‣ If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
You can order a weather protection cover from Endress+Hauser.
System pressure
Pressure-reducing valves and some compressor systems can generate significant processpressure variations that can distort the flow profile. This can produce an additional measured
error. Suitable measures must be taken to reduce these pressure pulses, such as:• The use of expansion tanks• The use of inlet diffusers• Positioning the measuring device further downstream
To avoid pulsating flow and contamination from oil/dirt in compressed air applications, it isrecommended to install the measuring device downstream of filter, drying and storage
devices. Do not install the measuring device directly after the compressor.
Thermal insulation
In the case of some fluids, it is important to keep the heat radiated from the sensor to thetransmitter to a low level. A wide range of materials can be used for the required insulation.
If the gas is very wet or saturated with water (e.g. digester gas), the pipe and the sensor
housing should be insulated, and heated where necessary, to prevent water droplets
condensing on the sensing element.

NOTICE
Danger of overheating when heating‣ Ensure that the temperature at the lower end of the transmitter housing does not exceed
80 °C (176 °F).
‣ Ensure that sufficient convection takes place at the transmitter neck.
‣ When using in potentially explosive atmospheres, observe the information in the devicespecific Ex documentation. For detailed information on the temperature tables, see theseparate document entitled "Safety Instructions" (XA) for the device.
‣ Ensure that a sufficiently large area of the transmitter neck remains exposed. The
uncovered part serves as a radiator and protects the electronics from overheating andexcessive cooling.
Heating options
If a fluid requires that no heat loss should occur at the sensor, users can avail of the following
heating options:• Electrical heating, e.g. with electric band heaters• Via pipes carrying hot water or steam
Vibrations
NOTICE
Strong vibrations can damage the measuring device.
Can result in damage to the measuring device or the fastening units.
‣ Pay attention to information on the vibration and shock resistance

Special mounting instructions

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions . Therefore, a zero point adjustment in thefield is generally not required.
Experience shows that zero point adjustment is advisable only in special cases:• If strict measuring accuracy requirements apply.
• Under extreme process or operating conditions (e.g. very high process temperatures or lightgases (helium, hydrogen)).

Mounting the sensor

LWARNING
Danger due to improper process sealing!
‣ Ensure that the inside diameters of the gaskets are greater than or equal to that of theprocess connections and piping.
‣ Ensure that the seals are clean and undamaged.
‣ Secure the seals correctly.
1.

Ensure that the direction of the arrow on the sensor matches the flow direction of themedium.

2.

Install the measuring device or turn the transmitter housing so that the cable entries do
not point upwards.
