too
much corrosion or liner inside the pipe)?
e) If there is any interference source around the flow meter?
§4.8.5 Note the following questions when installing
1
，
input pipe parameters must be correct,conform to actual facts,otherwise the flow meter will not
work.
2,when installing clamp on type transducers,apply enough couplant to make the transducers
attach on the pipe,check the signal streghth and signal quality displayed on the screen while
moving the transducers around installation point to receive the best signal and signal quality.the
diameter of pipe is more wider,the range of moving transducers is more larger.then ensure
whether the installation space is the same with that on M25,whether transducers are installed in
the same axis line of pipe.if the signal streghth is 0.00,that means no receipt of ultrasonic
beam,check whether the input parameters are correct or not, choosing installation method is
correct or not,whether the pipe is too old,liner is too thick,is there fluid in pipe
？
the space is too
near valves,angle head?too many air bubbles in fluid?if not these reasons,still no signal,so have to
try another point,or use insertion type transducers.
3,ensure whether the flow meter work normaly:signal streghth is bigger,signal quality is
higher,the displayed flow rate is more reliable,the meter can work for long time.if there is too
bigger environment electromagnetic interference or lower receiving signal,then the flow rate
displayed is poor,not be able to work normaly for long time.
4,after installation,enter M26 to solidify parameters,power on again,check results are correct
or not.
5.Troubleshooting
TDS-100M designed perfect self-diagnosis function.The errors are displayed on the upper
right corner of the menu window via identification code in a timely order.
Display orderly all the existing errors on M08
Hardware self-diagnosis is conducted every time when power is on. Some errors can even be
detected
during normal operation. For those errors undetectable due to incorrect settings
or improper testing
conditions, the flow meter will also display useful information to help the user to quickly debug the
error and solve the problems according to following listed methods.
Displayed errors of TDS-100M have two kinds:one is circuit hardware errors information,arising
possible problems and solve method can refer to table 1.if finding problems when power is on,and
in the state of measuring,it will display “* F”on the upper left corner of screen.power on
again,check the displayed information,adopts measures according to following table.if the
problems still exist,contact manufacter. The other is error information about measurement.refer to
table 2.
