Overview

LS-04/08 series flow meter is a new type of rotary piston flow meter
which is successfully invented  by  China  for the first time. With the
domestic  advanced  techniques,  low  limit of flow rate, wide range,
high precision,  simple structure ,  reliable  operation  and the lower
price  compared  with  the  same  volumetric  flow  meter ,  it can be
installed   in   trains,  tractors,   generator  sets,   inland or offshore
sailing ship directly to measure the  fuel consumption of all kinds of
machines,  the loading  and unloading  of  a  variety of heavy liquid,
the  liquid  through  pipelines.  It  is the best instrument of the liquid
material assessment  to  conduct  the  depth  of  the energy-saving
work, and also the ideal application  to transportation  vehicle  in  a
wide range, which  is  popular  by  the  energy measurement sector,
research  sector,  transport sector,  shipbuilding  manufacturer and
fluid manufacturers.

Working principle

Flow  meter  is  made  up  of  the  part  of  the  case and piston
institutions, etc. Counting structure  is completely  isolated from
the  oil  and  is  motivated   by   the magnetic  drive.  When  the
instrument  is  connected  to the pipeline and fuel flows through
it, the pressure  difference  of  import and export sides will drive
the piston  to  do  rotary motion. At the same time, the magnetic
coupler  which  is   connected  with  the  piston  will  also  rotate.
Because  the  piston rotation is proportional to the amount of oil
flow through the meter, the piston rpm recorded by the counting
structure is the multiple of fuel flow through the meter.

Dimension ( mm )

Size	Length	Width	Height	connection type of Flow meter
Model
LS-04	60	60	40	G1/8＂internal thread connection
LS-04LCD	60	60	100	G1/8＂internal thread connection
LS-08	73	73	45	G1/4＂internal thread connection
LS-08LCD	73	73	100	G1/4＂internal thread connection

The factory's standard configuration is'/2' external pipe thread
which can connect to the filter connector.
If there are too much Oil impurities, the flow meter must be added
with the standard fine filter.

 

Strainer connector

 

There is a stainless steel filter net inside the filter connector to

prevent oil impurity from entering into the flow meter's cavity

and block it. The filter net is fixed with Circlips for holes-type,

for easy cleaning and disassembly.

 

Show Table head instructions

●   LCD table head can display

three  interfaces:  total  flow(L),

instantaneous   flow ( L/h ) and

Single  flow(L).  push " " key

and    we    can    switch    three

interfaces over.

★    Any key operation will allow the backlight lit. If you press it and do not operate within 10 second, it will go out  

          automatically.

★    The battery reminder function: It flashes when the battery is low and should be replaced.

★    Continuous battery use time can last for more than 2 years. Standby mode can last for more than 6 years.
