Pipe O.D. in. and Pipe Wall in. , are the dimensions of the pipe in which the transducers will be
installed and are required to calculate the flow rate. The Pipe I.D. does not need to be entered as
it is calculated by the flow meter electronics. Appendix C contains typical pipe wall and outside
diameter (OD) information.
Pipe Material and Liner Material , if applicable, are the materials of the pipe in which the
transducers will be installed. Appendix C contains speed of sound information for various pipe
materials.
Transducer Type, defines the frequency of the transducer being used for measurement of the
liquid inside the pipe. The three transducer frequencies to choose from include 0.5 MHz, 1
MHz, or 2 MHz.
TransTraverses, defines the path of the ultrasonic sound wave that is being used for
measurement of the liquid inside the pipe. The selections include 1 path (Z), 2 path (V), or 4
path (W).
Spacing Temp , is used in calculations to determine the distance (spacing) between the scribe
lines of the transducers. Enter the temperature of the liquid being measured at the time the
transducers are being installed for measurement.
Fluid Temp 1, is the temperature of the liquid inside the pipe. The temperature can be entered
manually by selecting Don’t Use RTD . It can also be measured with a resistance temperature
detector (RTD) by selecting Use RTD . If Use RTD is selected and the meter display indicates a
temperature fault, a substitute value can be entered to allow flow calculations to continue at a
fixed value until the source of the fault is identified and corrected. This is accomplished by
selecting
Don’t Use RTD and entering the temperature of the liquid being measured. The units
of measure of the displayed values are the same as the units configured for the flow meter.
Note: if a V only model was purchased, select
Don’t Use RTD and enter the temperature of the
fluid being measured.
Sound Speed SRC, provides the user with three options for calculating the speed of sound of the
liquid being measured. Select Spacing Temp to use the temperature programmed for
determining the distance (spacing) between the scribe lines of the transducers to calculate the
speed of sound. Select TOF_Calc to use the measured time of flight (TOF) of the liquid being
measured to calculate the speed of sound. Select Fluid Temp 1 to use either the programmed or
measured temperature of the liquid to calculate the speed of sound.
