INTRODUCTION ........................................... Introduction By means of the transit times of ultrasonic pulses, the USZ 08 ultrasonic flowmeter measures the flow velocity of the gas from which it calculates the flow rate at measurement conditions. Here use is made of the fact that ultrasonic pulses move faster in the direction of flow than in the opposite direction.

INTRODUCTION ........................................... For non-fiscal metering also the 2-path design of typ USZ 08-2P can be used. This version is equivalent to a reduced 6-path design, which only has the two acoustic paths in the middle plain. Signals are evaluated by the USE 09(-C) ultrasonic electronic system which is installed on the meter case.

INSTALLATION AND COMMISSIONING ........................................... Installation and commissioning Installation of the meter The USZ 08 ultrasonic flowmeter is to be operated with an inlet pipe and an outlet pipe. The following details are identical to the requirements of the PTB approval certificate and are therefore binding for custody transfer metering.
INSTALLATION AND COMMISSIONING ........................................... Pipe diameter Ø i = D-2% ... D+5% Ø i = D-2% Ø i = D ... D+5% The inside diameters of the inlet and outlet pipes may be up to 2% smaller or up to 5% larger than the inside diameter of the meter.
........................................... Seals It must be guaranteed that flange seals of RMG turbine meters do not protrude from the flange into the gas line. All seals approved as per DVGW can be used depending on the requirements for stability and reli- ability.

Electrical connections Terminal assignments of the measuring element The USZ 08 ultrasonic flowmeter with the Terminals USE 09 ultrasonic electronic system is on the supplied with two case variants: electronics - with the mere electronics case: here card connection is to be made directly at the electronics card (standard with the...
INSTALLATION AND COMMISSIONING ........................................... The RS 485 0 interface is used for servicing. The RMGView service and diagnostic software which is required for this purpose is described from page 35 onwards. A second Flow Computer can optionally be connected to the RS 485 2 interface if an appropriate optional USE 09 card is used.

INSTALLATION AND COMMISSIONING ........................................... Start-up After the meter has been installed and the ERZ 2000 USC has been connected, the parameters of the meter have to be checked on the computer. They are listed on the verification certificate of the meter together with the coordinates.
OPERATING THE ULTRASONIC COMPUTER ........................................... Operating the ultrasonic computer General information about the ERZ 2000 USC Overview of functions Depending on the software installed, the ERZ 2000 device family is equipped with an integrated functional unit for direct connection to the ultrasonic measuring element (called IGM for Industrial Gas Meter in the software).
OPERATING THE ULTRASONIC COMPUTER ........................................... Usually, the variant of the device is set in the factory when the device is parameterized and cannot be changed on site anymore. If the switching facility has not been locked in the factory, it is possible to change the setting subsequently.
Page 28
OPERATING THE ULTRASONIC COMPUTER ........................................... The DZU operating mode (15) requires another functional unit (remote unit) to be interconnected between the measuring head and the volume corrector. This is either the external USZ 9000 remote unit which represents the main totalizer from the point of view of custody transfer metering or the USE 09-C ultrasonic electronic system with an integrated controller and main totalizer.

OPERATING THE ULTRASONIC COMPUTER ........................................... Error curve linearization of volume metering when using the USE 09-C The error curve linearization of the gas meter can optionally be performed using three different methods. Error curve linearization with polynomial related to the flow rate Error curve linearization with polynomial related to the Reynolds number Error curve linearization using the interpolation point method These methods are identical to the methods used in the case of turbine meters.
