The Energoflow AG LF series of Ultrasonic Liquid Flow Meters is designed to
perfection for reliable and accurate measurement of liquid flow in filled pipelines
using the pulse-time method. These flow meters can be used for flow monitoring
and measurement of potable, technical or river water, oil and petroleum products,
heat-transfer agent, solutions of alkalis and acids, warmed fuel oil, heavy oil, stable
gas condensate and liquefied petroleum gas, effluents, etc. at pressures up-to 250
bar. Special versions of this series of meters for specific applications like portable
in-situ flow measurement, flow measurement of high pressure streams etc. are also
available.
The Ultrasonic Liquid Flow Meters of the LF series are manufactured in various
versions for application over a vast range of process conditions :
● for pipelines from DN25 up-to DN7000
● for flow speeds as low as 0.1 m/s and as high as 12 m/s
● for ambient temperatures as low as -65 deg C and as high as +70 deg C and
at 100% humidity
● for liquid temperatures in the range of -20 deg up-to 150 deg C
● For installation in hazardous areas and hard to access locations
● for clamp-on installation, the process pressure is not a consideration
The major advantages of the Energoflow AG LF series Ultrasonic Liquid Flow Meters
are:
1. No obstruction to the flow and zero pressure loss
2. No moving parts and no mechanical wear or tear
3. Easy installation and simplicity of use
4. Easy integration into all kinds of process management systems
5. High accuracy, large turn-down ratio, reliable measurement and fast reaction
to changes in process conditions
The flow meters of the series are manufactured in various versions – with in-line
sections, with sensors inserted in existing pipelines and clamp-on type.
Ultrasonic Flow Meters are designed for single channel and two-channels. Each
channel can be used independently to account for liquid in different pipelines or two
carry out two channel flow measurement in a single pipeline.
Clamp-on sensors (mounted on the surface of the pipe with chain & clamp) and
inserted sensors (which are inserted in the pipe wall) can be used for larger pipe
diameters (up-to pipe DN 4 m, larger sizes under special order).
Power supply and connection unit (PSU) is equipped with the interface
RS-232/RS-485 for connection with computer. LF Flow meters forms also have have
pulse outputs and 4..20 mA current outputs.
LF meters with In-line sections are designed for medium gauge pressure upto 1,6
MPa and medium temperature from 0… 150 °C. They are available for sizes DN 50
upto DN 600. Other sizes can be supplied under order.
