(1) single-path system (v method) (2) single-path system (z method) measuring principle configuration the transit-time technique uses a pair of sensors with each sensor sending and receiving ultrasonic signals through the uid. when the fluid is flowing, signal transit-time in the down stream direction is shorter than one in the upstrream direc- tion. as the difference between these transit-time is proportional to the velocity, the ow rate and direction can be measured properly by detecting such time difference. flow transmitter flv: ?flow transmitter ?manual sensor flw, fld: ?sensor unit ?signal cable ?mounting chain/ belt/ wire ?silicone rubber/ grease (100gr) signal cable fly: orignal cable (2 wires) scope of delivery the product conforms to the requirements of the electromagnetic compatibility directive 89/336/eec as detailed within the technical construction file number tn510423. the applicable standards used to demonstrate compliance are : en 55011 : 1991 conducted and radiated emissions en 50082-1 : 1992 radiated immunity, esd and fbt classa detecter selection guide optional accessuries name drawing no. 1 guide rail for high-temperature sensor tk4c6164c1 output signal contact signal flow transmitter flow velocity v downstream-side sensor sensor upstream-side sensor d t 1 t 2 cable flow transmitter dc 4 to 20ma contact signal up to 2 points detector cable flow transmitter dc 4 to 20ma detector contact signal up to 2 points 200 100 80 0 ?40 50 13 100 200 400 1200 6000 pipe size (mm) large sensor (flw5) high-temperature sensor (fld3) small diameter sensor (fld2) fluid temperature (c) small sensor (flw1) middle sensor (flw4)
