4.6.2. Piping parameter setting method 
Description 
 Set the parameters of piping and fluid to be measured to determine the sensor mounting spacing. 
 The mounting dimension of the sensor is automatically calculated. Refer to “5.1.1 PRODUCT OUTLINE”. 
 
 
 
Be sure to set the following parameters before mounting the sensor on the pipe. Mount the sensor to match the sensor 
mounting length. 
 Unless the sensor units are spaced accurately, the measurement error will be excessive. 
 Also, the received wave may be abnormal. 
 
Setting items 
1.  Pipe outer diameter  : 6.00 to 6200.00 [mm] (factory set at 60.00 [mm]). 
2.  Piping material  : CARBON STEEL, STAINLESS STEEL, PVC (factory set), COPPER, CAST IRON, ALUMINIUM, 
FRP, DUCTILE IRON, PEEK, PVDF, ACRYLIC, PP, Others (Sound velocity: 1000 to 3700[m/s]) 
3.  Wall thickness  : 0.10 to 100.00 [mm] (factory set at 4.00 [mm]). 
4.  Lining material  : NO LINING (factory set), TAR EPOXY, MORTAR, RUBBER, TEFLON, PYREX GLASS, PVC, 
Others (Sound velocity: 1000 to 3700[m/s]) 
5.  Lining thickness  : 0.10 to 100.00 [mm] 
6.  Measuring fluid  : WATER, SEAWATER, DIST.WATER, AMMONIA, ALCOHOL, BENZENE, ETHANOL, GLYCOL, 
KEROSENE, MILK, METHANOL, TOLUOL, LUBE OIL, FUEL OIL, PETROL, REFRIGERANT 
R410, Others (Sound velocity: 300 to 2500[m/s]) 
7.  Dynamic viscosity coefficient : 0.0010 to 999.999 × 10

8.  Detector mounting method  : V method (factory set), Z method    Refer to “5.2.Selection of mounting method” 
9.  Detector type  : FSSA/FSSG (factory set), FLS_12/FLS_22, FSSC,FSG_32, FSG_31/FSG-41, FSSE/FSG_50, 
FSSF/FSG_51, FSD12, FSSD/FSD22,FSSH/FSD32 
   
Note) If the sensor type is previous type, make a setting change for current type. 
Previous type  Current type  Previous type  Current type 
FLD22 FSD22 FLW41 FSG_41 
FLD32 FSD32 FLW50 FSG_50 
FLW11 FSG_31 FLW51 FSG_51 
FLW12 FSG_32     
 
For concrete keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.) 
 
(1) Setting method when sensor type is “FSSA”. 
Operation 
(example) 
Carry out setting for measuring the flow rate of water flowing through PVC pipe (for tap water) using FSSA detector.
