Simple set-up procedure.
These vortex flowmeters clamp on the outside of your
pipes and measure the liquid flow in full pipes. They have the unique advantage
that no mechanical parts enter through the pipe wall and into the process
The Vortex can be used with a wide range of pipe materials and sizes
that contain any liquid that can transmit ultrasound, including liquids that
contain a small percentage of entrained solids.
Ultrasonic flowmeters are
now accepted as being a viable method of measuring liquid flows, as their
performance and reliability have improved.
Setup of the instrument is carried out using a keypad
and LCD display. Data is entered relating to pipe size, material, liquid and
application temperature. The user selects the measurement units, the 4-20 mA
output levels and the other optional features.
All testing is carried out against a NAMAS accredited
meter traceable to National Standards.
The Ultraflo is for wall mounting installations and the
handheld Portaflo is for mobile applications.
The transducers are provided
with all of the necessary mounting hardware and can be installed within a
matter of minutes.
The flow rate, velocity and total can be displayed.
Features include flow averaging, negative flow indication, low flow alarm,
variable damping, totaliser reset, signal loss compensation and totalised flow
The Ultraflo has a wall mounting ABS case and is
protected to IP67. Cable entry is via IP68 glands. All instruments are shielded
against electromagnetic radiation.
Principle of Operation
When ultasound is transmitted between two sensors in a
pipe in the direction of flow then the signal is accelerated by the flowing
liquid. Ultrasound transmitted in the opposite direction will be decelerated.
The time difference between the signals is directly proportional to the flow
velocity in the pipe. The S Series are suitable for filling, fuelling, batching
and monitoring. You can use them to meter oils, petrol, diesel and
