1.7 Returning devices
Use the original packaging or a secure transport container of an appropriate type if you need to
return the device for repair or recalibration purposes. Fill out the return form (see the Appendix)
and include this with the device.
The EU Directive governing hazardous materials dictates that the owners of any hazardous
waste are also responsible for disposing of it.
All devices delivered to the manufacturer must be free from any hazardous materials (acids,
alkalis, solvents, etc.).
Pipe components and flowmeter sensors contain hollow spaces. If they have been used in
conjunction with hazardous materials, they must therefore be rinsed out in order to neutralize
any such substances.
The owner will be charged for any costs incurred as a result of the device not having been
adequately cleaned or of any failure to dispose of hazardous materials. The manufacturer
reserves the right to return a contaminated device.

companies.
1.9.1 Information on WEEE Directive 2002/96/EC (Waste Electrical and Electronic Equipment)
This product is not subject to WEEE Directive 2002/96/EC or relevant national laws
(e.g., ElektroG in Germany).
The product must be disposed of at a specialist recycling facility. Do not use municipal garbage
collection points. According to the WEEE Directive 2002/96/EC, only products used in private
applications may be disposed of at municipal garbage facilities. Proper disposal prevents
negative effects on people and the environment, and supports the reuse of valuable raw
materials.
If it is not possible to dispose of old equipment properly, ABB Service can accept and dispose of
returns for a fee.
1.9.2 RoHS Directive 2002/95/EC
With the Electrical and Electronic Equipment Act (ElektroG) in Germany, the European
Directives 2002/96/EC (WEEE) and 2002/95/EC (RoHS) are translated into national law.
ElektroG defines the products that are subject to regulated collection and disposal or reuse in
the event of disposal or at the end of their service life. ElektroG also prohibits the marketing of
electrical and electronic equipment that contains certain amounts of lead, cadmium, mercury,
hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers
(PBDE) (also known as hazardous substances with restricted uses).
The products provided by ABB Automation Products GmbH do not fall within the current scope
of the directive on waste from electrical and electronic equipment according to ElektroG. If the
necessary components are available on the market at the right time, in the future these
substances will no longer be used in new product development.

1. Fit the flowmeter sensor in the measuring section. Ensure that the tapered flange connection
is secure (tightness) and observe the flow direction (direction indicated by arrow).
2. Connect the flowmeter sensor and supply / evaluation unit using the flowmeter sensor cable
(7-pin).
3. Use the power cable supplied to connect the supply / evaluation unit to the permissible
supply voltage.
4. Switch on the measuring system using the master On / Off switch.
Important
Before the device switches to the actual measuring mode, it performs a self-test, during which
all the indicators on the "DISPLAY" light up. After a minute, the device is ready for operation. It
then takes approximately half an hour to reach maximum measuring accuracy.
The measuring rate is set to N = 100. If you require a different measuring rate (option), please
refer to section 5.3.1.
Whenever communication between the flowmeter sensor and supply / evaluation unit is
interrupted, e.g., after the flowmeter sensor has been changed, you must remember to press
the "RESET" button.
If no flowmeter sensor is connected, the "EO2" error message appears to indicate this.
If the "E11" error message appears, it means that you have either pressed the "TEMP" button
when there is no temperature sensor with a temperature option or that an error has occurred
in the temperature evaluation system.

The supply / evaluation unit involves the use of microprocessor technology. The transmitter
signal is linearized and shown directly as a mass or standard volume flow value (e.g., in kg/h or
m3N/h)
Thanks to the microprocessor, one supply / evaluation unit can cater for all flowmeter sensor
nominal diameters with a standard measuring range. It also makes for user-friendly operation.
The device is available as a 19" plug-in module or as a portable desktop unit for a variety of
supply voltages (see the section titled "Specifications").

The measuring range of the relevant transmitter is detected automatically when the flowmeter
sensor is connected. Measuring range detection has to be performed if there are two flowmeter
sensors connected (see section 5.5) and if the measuring signal is to undergo downstream
processing in analog format. This measuring range assignment is available at the "analog
outputs" socket as a binary code (see section 3.4).

5.3.1 Adjustable measuring rate
It is often useful to produce an average from the configurable number of individual
measurements. You can set the required number of individual measurements using the selector
switch on the front of the supply / evaluation unit.
A measuring cycle period (time for an individual measurement) lasts approximately
3 milliseconds. The average value calculated for the number of individual measurements
configured is displayed and made available at the interfaces. In standard mode (i.e., when the
device is switched on/before the set measuring rate is adopted), the device automatically
generates an average value from 100 individual measurements.
If the device generates an average value from fewer than 100 individual measurements, the set
measuring rate is used for the analog outputs and the 12-bit parallel interface.
However, the digital display and the serial interface still contain measured values
reflecting an average value for 100 individual measurements.
Proceed as follows to set a measuring rate:
1. Set the required measuring rate using the selector switch on the front of the
supply / evaluation unit.
2. Press the "SAMPLE RATE" button to accept the set measuring rate. The selected measuring
rate appears briefly in the display field as an acknowledgment signal. The measured value
that appears after that is the first of the average values to be calculated from the newly
configured number N.

Important (Notice)
Whenever the measuring system is switched on or after a reset, the device adopts a
measuring rate of N = 100 as soon as the internal test routines have been completed.
Example:
The average mass flowrate needs to be determined using an interval of 3 seconds.
What measuring rate should be set?
3 s = 3,000 ms
N = 1 = 3 ms
Presetting counter setting

= I

Required interval
Duration of a single measurement
No. of individual measurements
1000
3
3000I T
N
Thus, the measuring rate should be set to N = 1,000 on the switch.
This means that the four-digit switch can be used to produce an average value for the mass
flowrate based on up to 9,999 individual measurements.
When a measuring rate of "0000" is selected, the measuring cycle period is just 1 millisecond
(see section 5.3.2).
To summarize:
• If a low measuring rate is set, the average is produced from a small number of individual
measurements and it is possible to measure and record dynamic processes.
• If a high measuring rate is set, the average is produced from a large number of individual
measurements and undesirable fluctuations can be eliminated.

5.3.2 Fast measuring rate
This operating mode is for measuring very fast, dynamic processes. The measuring cycle
period is 1 ms, i.e., an updated measured value is made available at the analog outputs and at
the 12-bit parallel interface once every millisecond.
Proceed as follows to set this operating mode:
• Set the measuring rate to "0000" using the switch on the front of the supply / evaluation unit.
• Press the "SAMPLE RATE" button to accept this measuring rate. "_ _ _ _ _ _ " appears
on the display along with "FAST MODE".
Important (Notice)
If you want the device to revert to the default setting (N = 100), you need to reset it (press
RESET button) or restart it completely.
As soon as the internal test routines have been completed (during which all the indicators light
up), the measuring system starts taking measurements using the default measuring rate
setting of N = 100 again.

5.3.3 Analog outputs
The following 3 analog outputs are available as options:
0 ... 10 V
0 ... 20 mA
4 ... 20 mA
The previously set measuring rate (see section 5.3.1) is used for the analog interfaces.
Additional signal-processing units can be connected to the analog outputs, e.g.:
• A recorder
• An oscilloscope
• A transient recorder
• A process computer
• A controller
This makes it possible to visualize and record rapidly changing flowrates.
The Sensyflow FMT700-P measuring system has been specially developed for applications that
call for a rapid response time where changes in flowrate are concerned. Fig. 15 illustrates the
high speed of the measuring signal response when a throttle valve opens compared with the
sluggish behavior associated with a orifice plate.
