4.6.4. How to set the piping parameters
Description
z
Set the parameters of piping and fluid to be measured to determine the sensor unit spacing.
Set the following parameters, calculate the sensor unit spacing value and then, to match the result, install the
sensor units into the frame.
z
Unless the sensor units are spaced accurately, the measurement may demonstrate excessive error.
z The received signal waveform may be abnormal as a result of incorrect piping or fluid parameters.
Setting item
1. Pipe outer diameter : 10 to 650 [mm] (factory set at 60.00 [mm]).
2. Pipe material : PVC (factory set), PVDF, PEEK, PP, CARBON STEEL, STAINLESS STEEL,
COPPER, others (sound velocity 1000 to 3700 m/s).
3. Wall thickness : 0.1 to 50.00 [mm] (factory set at 4.50 [mm]).
4. Lining material : NO LINING (factory set), TAR EPOXY, MORTAL, RUBBER, TEFLON,
PYREXGLASS, others (sound velocity: 1000 to 3700 [m/s]).
5. Lining material thickness : 0.01 to 50.00 [mm].
6. Fluid to be measured : WATER, SEA WATER, others (sound velocity: 500 to 2500 [m/s])
7. Kinematic viscosity : 0.0001 to 999.9999 u10 -6 [m 2 /s] (factory set at 1.0038 u10 -6 [m 2 /s])
8. Detector mounting method : V method (factory set), Z method
9. Detector type
: SX3A (factory set), SX3B, SX3C, SX3D
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand
(Section 4.4.1)
Typical operation Carry out setting for measuring the flow rate of water flowing through PVC pipe (for tap water)
having 100 mm of nominal diameter.
