4.transducers installation
§4.1 Unpack checking
Check whether the spare parts comply with packing list,enclosure is broken or not during
transportation?did screw drop?connecting line is loose or not?if have questions,pls cotact factory.
§4.2 Power supply and cable
When users place an order,pls inform factory what kinds of power supply is
needed,normaly the power supply of the flow meter have following options:
: DC24V or DC8~36V
Transducers signal cable of TDS-100M series ultrasonic flow meter adopts high frequency special
shielded twisted pair cable.because sending and receiving circuit adopts balanced transmitting
and balanced receiving principle.so to increase the anti-interference function,little signal
consumable ,ensure the device work well in longer term.so the special signal cable supplied by
factory is the best choice for you.if using coaxial shielded radio frequency cable or poor quality
twisted pair cable,it could lower accuracy and the function of the device.when there is bigger
interference signal from outside,the device could not measure normally.
§4.3 Required installation condition
Installation of The new TDS-100M series is the easiest and convenient way in the
installation of all flow meters,just choosing a suitable measurement point,input the pipe
parameters of this pipe point to the flow meter,then fix the transducers on the pipe.
§4.3.1 choosing measurement point
To ensure measurement accuracy and stability,the installation point of tranducers should be on
the straight pipe full of well distributed fluid(when installing,the pipe must be full of liquid),comform
to following principle:
1.Pipe must be full of liquid that is uniform and easy to travel the ultrasonic beam(vertical pipe or
horizontal pipe)
2.Upstream transducer should be installed at the place where the upstream length of the straight
