The following conditions can increase the risk:
● Toxic gas or gas dangerous to health
● Chemically aggressive gas
● Explosive gas
● High gas pressure
● High gas temperature
▸ Only carry out installation work when the system is out of operation and
does not contain dangerous gas.
Otherwise escaping gas can possibly be dangerous to health and cause
injuries (e.g. poisoning, burns).
WARNING: Hazards through leaks
Operation in leaky condition is not allowed and possibly dangerous.
▸ Check leak tightness of equipment regularly.

1.3.3 Operation in potentially explosive atmospheres
1.3.4 Operation in pressure applications
Design, manufacture and inspection of the FLOWSIC30 measuring system is performed in
compliance with the safety requirements set forth in the ASME standard B31.3.
1.3.5 Operation in applications with wet gas
FLOWSIC30 has been designed for robust and reliable operation in challenging gas produc-
tion applications. In these applications, wet gas may also be existent in the gas stream.
However, FLOWSIC30 is a gas meter. All specifications of the gas meter apply for dry gas
only. Any wet gas in the gas stream may adversely affect the certainty of the measured
values and meter function.
→ Fig. 2 shows the gas meter's operating range at low pressure in horizontal and in vertical
meter orientation. Horizontal installation of the gas meter is recommended for wet gas
applications.
Since the effects of 2-phase streams with mixtures of liquid and gas are very complex, a
general operation guarantee cannot be given for the gas meter in these conditions.

2.1 Functional principle
The FLOWSIC30 works according to the principle of ultrasonic transit time difference
measurement. Measured signal travel times tAB and tBA are defined by the current sound
and flow velocity of the gas.
Gas velocity v is determined from the difference between the signal travel times. Therefore
changes in the sound velocity caused by pressure or temperature fluctuations do not affect
the calculated gas flow rate with this method of measurement.
Fig. 3 Measuring principle FLOWSIC30
2.2 Calculations
2.2.1 Determining the gas velocity
Measuring path L is equal to the active measuring path, that is, the area through which the
gas flows. Given measuring path L, sound velocity c, and angle of inclination α between the
sound and flow direction, the sound transit time in the direction of the gas flow (forward
direction) when the signal is transmitted can be expressed as:
i.e. a relation in which, except for the two transit times measured, only the active measuring
path and the path angle exist as constants.

2.2.2 Determining the sound velocity
Sound velocity c can be calculated by resolving formulas 2.1 and 2.2.
2.2.3 Calculating the volume flow rate a. c.
The volume flow rate in actual condition (a. c.) is calculated from the gas velocity and the
geometric dimensions of the meter body diameter D.
2.2.4 Calculating the methane content
The calculation of the methane content is made by a simple model based on the measured
speed of sound in the medium. It can be used to identify changes in the gas composition
that may require appropriate action by the plant operator. The underlying model has been
created primarily for unconventional natural gas with high contents of methane.
The algorithm is based on the following assumptions:
● The main components are N2, CO2 and CH4, all other components exist only in
negligible amounts.
● The portion of N2 is roughly twice the portion of CO2.
● Significant amounts of other substances may lead to deviations.

2.2.5 Volume conversion (option)
As an option, FLOWSIC30 can be ordered with electronic volume conversion.
The optional Electronic Volume Converter (EVC) provides the capability to convert the
measured values in actual condition (a. c.) to standard condition (s. c.). Various standard
conditions can be defined.
Table 1 Measured values
The gas compressibility calculation is made acc. to AGA 8 Gross method 1 or 2. It requires
input of certain process values such as gas pressure and temperature. Settings can be
made in the FLOWgateTM operating software or via HART® protocol.
Prerequisites for volume conversion
● Actual process pressure is fed into FLOWSIC30 by one of the methods below:
– The process pressure is set to a fix value in FLOWSIC30.
– The process pressure is read in from an external HART® pressure sensor connected
to the HART® bus. The p sensor is then loop powered.
– The process pressure is read in from an internal pressure sensor.
● The p sensor and the FLOWSIC30 are configured as follows:
– The p sensor and the FLOWSIC30 are in multidrop mode.
– The p sensor is in burst mode or must be polled periodically by HART® master.
● The p sensor has been fully configured in FLOWSIC30.

2.3 System overview
The FLOWSIC30 is designed for use in natural gas production applications for gases such
as coal bed methane. The dual-path meter comes with a robust carbon steel meter body
and full-titanium transducers.
The ultrasonic measurement technology has no moving parts and is virtually maintenance
free. The rugged design with integrated wires protects the gas meter from harsh ambient
conditions while the large turn-down ratio covers all well flow rates. FLOWSIC30 is equipped
with integrated diagnostics that monitor the meter status and indicate the presence of
liquids in the gas stream.
With integrated temperature and pressure measurement and optional volume conversion
according to AGA 8, the gas meter calculates the volumetric flow s. c. and reduces installa-
tion efforts. Power consumption of only 65 mW and the two-wire loop powered concept
make integration easy while HART® and Modbus communication provide versatility in data
transfer.
FLOWSIC30 is available as wet-gas robust or wet-gas tolerant design.
Wet-gas robust design
The wet-gas robust design was designed specifically for wet gas applications in natural gas
production with installation upstream of separators. The device is also suitable for
continuous wet gas operation with a high liquid loading.
Wet-gas tolerant design
The wet-gas tolerant device design was designed for installation behind separators. The
device can measure in continuous wet gas operation with low liquid loading. Temporary
high liquid loads can lead to limited measuring availability. As the liquid load decreases, the
gas meter recovers completely, e.g. in case of temporarily reduced separator performance.
The lower wet gas robustness enables improved measurement accuracy.
System components
The FLOWSIC30 measuring system comprises the following hardware components:
● Meter body
● Ultrasonic transducers
● Temperature sensor (option)
● Internal pressure sensor (optional)
● Signal processing unit (SPU)

face can be used also to transmit additional measurement data. Optionally, FLOWSIC30
can be ordered with an additional Modbus RS485 interface.

● HCF_SPEC-301, revision 6.0
● HCF_SPEC-151, revision 8.0
● HCF_SPEC-99, revision 8.0

● HCF_SPEC-81, revision 8.0
The device type code of the FLOWSIC30 gas meter is 0xC782 (FieldComm/HART® Founda-
tion registration pending) .
Point to point wiring
The device supports point-to-point connections. A host and/or a field communicator can be
integrated into the bus as communication master(s). Communication may run through Ex
isolators according to the HART® specification. Any polling address in the HART® address
range can be used to address the device. The polling address must be configured by the
software using the command #6 (default: 0).
Network (Multidrop)
The device can also be integrated into a network. Polling addresses must not be used more
than once in the network. If the device is integrated into a network, its polling address must
be greater than zero. In this mode the signal of the analog loop does not represent a
quantity measured by the device. A host and/or a field communicator can be integrated
into the bus as communication master(s). The number of devices in the network is limited
by the number of possible device addresses.
