2. PRODUCT DESCRIPTION
The flowmeter of the series EE772, based on the measurement principle of thermal mass flow, is suited for
the measurement of flow of air and gasses in pipelines. Measurement of for instance the consumption of
compressed air, nitrogen, helium, CO2 or other non-corrosive and non-flammable gasses.
The EE772 measures the volume flow at standard conditions according to DIN 1343 (P0=1023.25 mbar;
t0=273.15 K or 0 °C (32 °F). In addition to the standard volume flow, the measurand mass flow, norm flow and
temperature are available.
The EE772 has an integrated consumption counter. The consumption quantity is indicated in the display and
is not lost after a power failure. Two signal outputs are available. Depending on the application, the outputs
can be configured as analogue (current or voltage), switch output or as pulse output for the measurement of
the consumption.
Mounting valve - MultiController
The mounting valve assembly allows for the easy and reliable
installation within the pipeline. During installation in the pipeline,
observe the required inlet and outlet paths (see page 9). The
nominal size of the mounting valve must match the nominal size
of the pipe. The MultiController is suitable for pressures up to
40 bar (580 PSI) and available for pipe diameters DN40 (1 1/2”)
to DN80 (3”).
The MultiController with hot tap valve allows for the installment
and removal of the sensing probe under pressure without inter-
rupting the process flow.
Signal conditioning with optional display
The enclosure with the signal conditioning is mounted either on
the measurement probe (model A or B compact) or is remote
with a plugable sensor cable up to 10 meter (33 feet) – (model
C with remote probe).
Sensing probe with measurement electronics
The interchangeable sensing probe contains the sensor ele-
ment and the measurement electronics, in which the data of the
factory calibration is stored. The sensing probe is easy and
quickly interchangeable in the eld, independent of the elec-
tronics for the signal conditioning. After the exchange, the con-
guration of the outputs is unchanged.
Screw cap
The screw cap, with female thread, is screwed in place if the
flowmeter is not installed and the pipeline has to be used.
Sensor cable (only by model C with remote sensing probe)
The sensor cable allows for the remote installation, up to 10
meter (33 feet), of the sensing probe from the housing with the
signal conditioning.

3.2. Determining installation site
• The installation site should be easy accessible and free of vibrations and shocks.
• Observe at least 260 mm (10.24 inch) clearance above the housing with the signal conditioning, in
order to be able to remove the sensing probe if necessary.
• The ambient temperature should not exceed the value as stated in the specifications (see page
20) – consider heating by radiation.
• The fluid should not condense at the installation site. Condensation on the tip of the sensing probe
must be avoided.
• In compressed air systems, the installation should be downstream of the dryer.
• Observe the direction of the flow by the installation (see page 10).
• Observe the recommended straight pipe lengths up and downstream, in order to warrant the speci-
fied measurement accuracy.
• The flowmeter should be installed as far as possible from any flow disturbance. Valves or check-
valves should be installed in a respective distance from the flowmeter.
3.3. Installation position
Make sure that the arrow on the tip of the sensing probe is pointing in the direction of the flow.

3.4. Required length of straight pipe
The flowmeter should be installed as far as possible from disturbances of the flow. The causes for disturbance
of the flow are for instance, reducers, elbows, T-pieces, valves, gate valves, etc. The specified measurement
accuracy can be achieved only when the following straight inlet and outlet pipe lengths are installed:
• The wall thickness of the inlet and outlet pipe should be 2,6 mm
• The stated values are as a minimum. If possible, allow for greater distances.
• Valves or gate valves should be installed downstream of the flowmeter.
• With lighter gasses the inlet straight pipe should be longer.

3.5. Assembly of the measurement section
In order to install or remove the measurement section the pipeline system
should be depressurized.
• All connections to be made with appropriated sealing material on the threads.
• The sealing material should not change the area of the inner cross section of the pipe. It must be
warranted that the connections after installation are free of leaks.
• All fittings must be tested on seal tightness.
• Make sure during the assembly of the measurement section that the arrows on the pipe section
and the ball valve are pointing in the same direction as the flow.
• The recess for the alignment pin must be at the side of the outlet.
3.5.1. Assembly without flowmeter, but with screw cap instead (blind cap)
In order to use the measurement section without the flowmeter, the blind screw cap
(in the scope of supply) must be screwed tight onto the opening of the MultiController.
If not needed the screw cap can be screwed and stored on the side of the
MultiController.

3.6. Installation of the flowmeter sensing probe
3.6.1. Flow direction
The flow direction is indicated with an arrow on the tip of the probe. Due to the alignment pin is the installation
of the sensing probe in the MultiController only possible in the direction of the flow. After a removal, the sens-
ing probe will be re-installed in the measurement section in exactly the same position as done at the factory.
Hence, the highest reproducibility is guaranteed.

6. ERROR MESSAGES
In case the flowmeter is equipped with the optional display, the following error message can be indicated.
ERROR 01: sensing probe is not detected
Cause: the sensing probe is not connect or is defect
Effect: the display indicates “0” for all measurand. The analogue output defaults to the lowest
configured value.
Action: check the head of the sensing probe for visual damage.
check the sensor cable from the sensing probe to the electronics of the signal conditioning.
ERROR 02: the EEprom is defect
Cause: the EEPROM for the storing of the consumption counter and MIN /MAX value is defect.
Effect: the consumption counter and MIN / MAX values are no longer available. All measure-
ment values though are still indicated. The analogue, relay and pulse output are still
functional.
Action: return the flowmeter to the manufacturer.
7. MAINTENANCE
7.1. Removal of the sensing probe of the MultiController
MultiController without hot tap valve
Make sure that the pipe line is depressurized!
• Loose the retainer nut and pull the sensor probe from the MultiController.
• Operation without the flowmeter installed page 10.
7.2. Removal of the sensing probe of the hot tap valve
The sensor can be removed under pressure without flow interruption.
• Turn the hot tap valve with the hand without tools (anti-clockwise rotation) in the position SERVICE
- CLOSE.
• Only if the hot tap valve is fully in the position SERVICE - CLOSE the sensor is hermetically sealed
against the pressurized line.
• Loose the retainer nut slowly. Let the air exhaust slowly and make sure that is was only the relief
pressure and the hot tap valve is hermetically sealed.
• Loose the retainer nut and pull the sensor probe from the hot tap valve.
• Operation without the flowmeter installed page 10.
The sensor head is sensitive. Use the protection cap for transport and storage!
7.3. Cleaning of the sensor of the flowmeter
Do not use an abrasive cleaning agent, an organic solvent containing halogen or acetone.
• Clean the head of the sensor probe by carefully swirling in warm water of isopropyl alcohol. It is
recommended to use isopropyl alcohol if the pollution is crease or oil.
The sensor should not be touch by fingers or solid objects like screwdrivers or brushes!
• Leave the sensor to dry in ambient air.

1) The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation). The accuracy was
culated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
2) The flow meter is calibrated at 7 bar (abs) 101.5 Psi. If the working pressure is different from 7 bar (101.5 Psi) you can compensate the error by setting the actual
pressure with the configuration software.
