ULTRASONIC FLOWMETER
These are non
intrusive flowmeters to clamp on the outside of a pipe to measure the flow of
liquids.
Low cost: minimal installation cost
Wide range of pipe
sizes and applications
No interruption of the process either for
installation or maintenance
No intrusive mechanical hardware causing a
pressure drop or requiring removal for maintenance
Simple set-up
procedure.
Application
These ‘transit time’ ultrasonic 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 fluid.
The Ultraflo and Portaflo 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
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.
Calibration
All testing is carried out against a NAMAS accredited
meter traceable to National Standards.
Installation
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.
Display
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
data storage.
Construction
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
chemicals.
