ALTOSONIC V

1.1 Five-beam ultrasonic flowmeter

PRODUCT FEATURES 1

KROHNE's ALTOSONIC V
flowmetering. The absence of obstructions or moving parts in the pipe, ensures no wear or
pressure loss. This, in combination with larger meter sizes permits simplified configuration of
metering systems. For example no strainers and less parallel lines are required.

Operation is maintenance free. No periodic calibration is required, drastically cutting cost for
on-site equipment and procedures. This all results in considerable cost savings in both capital
(CAPEX) and operation expenditure (OPEX).

New line extensions make multi-beam flow metering a more cost effective and viable alternative
for low viscosity applications. There is also a line extension for extremely difficult heavy crudes.

ALTOSONIC V has established itself as the standard in multi-beam custody-transfer

1 PRODUCT FEATURES

1.2 System components

The ALTOSONIC V is more than a simple meter. It is a 3 component system:

• UFS-V, Ultrasonic Flow Sensor

• UFC-V, Ultrasonic Flow Converter

• UFP-V, Ultrasonic Flow Processor

The flow converter and flow processor are intended for controlling an ultrasonic flow sensor and
processing its output signals. Equipment connected to the flow processor's input can be used to
determine the volume under reference conditions and to generate indications and printouts of
the measured / calculated quantities.

Stainless steel, fully welded design which contains 5 pairs of
transducers transferring signals to the flow converter. In
addition, a body temperature sensor is integrated to
compensate for body expansion.

UFC-V, Ultrasonic Flow Converter

UFC-V, Ultrasonic Flow Converter

UFC-V, Ultrasonic Flow ConverterUFC-V, Ultrasonic Flow Converter
For each independent measuring path, the flow converter
determines the time of flight, relative flow rate per path and
more, based on the received raw data from the flow sensor
and transfers this information via an RS485 information
string to the flow processor.

UFP-V, Ultrasonic Flow Processor

UFP-V, Ultrasonic Flow ProcessorUFP-V, Ultrasonic Flow Processor
The flow processor determines the gross flow based on the
information received from the flow converter. Using
measured pressure, temperature, and optional density, the
UFP also calculates the standard flow. The results and
diagnostics are shown on-screen or fed further to the
supervisory system.

Two versions are available of the processor:

• a panel-mounted version complete with HMI, and

• a compact housing for part of a system build.
