If it is necessary to exactly determine a minimum flow rate, proceed to a calculation in the following manner. Example 1 Suppose the fluid is air, the temperature 20°C, the pressure 0.5 MPa (gauge), and the nominal piping diameter 80 mm. How can the minimum flow rate nominal diameter be found? The minimum flow rate at nominal diameter of 80 mm at air of 0.4 and 0.85 MPa in Table D is, according to Table C, 47 and 38 m3/h, respectively. At a pressure of 0.5 MPa, therefore, the minimum flow rate is, according to interpolation, Qmin = 38+ 0.85-0.5 × (47-38) 0.85-0.4 45m3/h Example 2 Suppose the fluid is carbon dioxide, the temperature 5 to 30°C, the pressure 0.8 to 1.5 MPa, and the maximum flow rate 800 m3/h (normal). How can the minimum flow rate and the applicable nominal diameter be found? First obtain the actual maximum flow rate, and then determine the nominal diameter. For calculating the maximum flow rate when the temperature and pressure have ranges, retain the higher temperature and lower pressure. Therefore, the actual maximum flow rate is: QMax. = 800 × 273.15+30 0.1013 × 273.15 0.1013+0.8 99m3/h Or the minimum flow rate can be obtained upon calculating an actual density. Actual density ρ of air at 20°C and 0.5 MPa is: ρ = 1.293 × 273.15 0.1013+0.5 × 273.15+20 0.1013 7.04kg/m3 Therefore, the nominal diameter is 40 mm. For obtaining the minimum flow rate, retain the lower temperature and higher pressure. From Tables C and D, the minimum flow rate at nominal diameter of 40 mm and pressure of 0.95 MPa is 9 m3/h or, at pressure of 1.7 MPa, is 8 m3/h. Therefore, according to interpolation, Qmin = 8+ 1.7-1.5 × (9-8) 1.7-0.95 8.3m3/h Note: If the calculated result has a value below decimal point, truncate it for maximum flow rate, or round it up for minimum flow rate. From Table C, the minimum flow rate at density of 6 and nominal diameter of 80 mm is 47 m 3/h and, likewise, at density of 11, is 38 m 3/h. At density of 7.04, therefore, the minimum flow rate is, according to interpolation, Qmin = 38+ 11-7.04 × (47-38) 11-6 45m3/h 3 FMR, M ¡Saturated vapor Pressure MPa (gauge) 0.049 0.098 0.196 0.294 0.392 0.490 0.588 0.686 0.785 0.883 0.981 1.08 1.18 1.27 1.37 Nominal diameter 15mm 5.4 6.1 8.0 9.5 11 13 14 15 16 17 18 19 20 21 22 15 20 29 38 47 56 65 73 82 91 99 108 117 125 133 14 15 20 24 27 30 33 36 39 42 44 47 49 52 54 25mm 51 67 98 128 158 187 216 245 275 303 333 362 391 417 446 22 25 33 40 45 51 56 61 65 70 74 78 83 86 90 40mm 102 133 194 254 313 371 429 487 545 602 661 718 776 827 885 36 41 54 64 74 83 91 99 107 114 121 128 135 141 147 50mm 172 224 325 425 524 621 718 815 912 1000 1100 1200 1290 1380 1480 80mm 79 90 118 141 162 181 199 217 234 250 265 281 295 308 323 641 834 1210 1580 1950 2310 2670 3030 3390 3750 4110 4470 4830 5150 5510 100mm 135 154 202 241 277 310 342 372 400 428 455 481 507 529 553 1100 1440 2090 2730 3370 4000 4620 5240 5860 6480 7100 7730 8350 8900 9520 Minimum Maximum Minimum Maximum Minimum Maximum Minimum Maximum Minimum Maximum Minimum Maximum Unit: kg/h Transducer integration reading unit The integration reading is in the same unit system as for flow rate.

Thermal insulation procedure For thermal insulation of piping, we recommend you to adopt a simplified thermal insulation (without mortar finish) on the flowmeter mounting section for facilitating disassembly or checkup. This arrangement allows to loosen flowmeter connecting bolts without breaking the thermal insulating material covering.

Flush mount type FEATURES 1. One-chip CPU mounted on this instrument has permitted many functions. Pressing pushbutton enables switching to the following 4 display modes. q Total flow, w Zero reset total, e Instantaneous flow rate (switching between per hour display and per minute display is possible.), r Meter coefficient 2. This instrument has a function of a scaler and of a divider. Wall type 3. It converts input pulse signal representing flow rate into an analog signal through built-in F/I conversion circuit. (Option) 4. Equipped with pulse output before or after the correction SPECIFICATIONS Item Display method LCD Height of letters: 12.7mm Pressing "MODE" switch allows the following display modes to rotate. (Mode display such as b1, b2, and c is displayed on the most significant and the second digit of the display window.) Description Display Digit Mode Not resettable to 0 Total flow 8  ** Per hour Instantaneous flow rate 5 b1 ** Per minute Instantaneous flow rate 5 b2 Resettable to 0 Total flow 7 c 0 (1/1), 1 (1/10), 2 (1/100) Divided value* 1 d 0.0001 to 1.9999 Meter coefficient* 5 F 1 to 128 Number of cycle samples 3 A *: Not displayed when "SELECT" switch is turned to "0" or "8". When "SELECT" switch is turned to "4" or "c", the values of the above 7 items are displayed. The setting of "Divided value", "Meter coefficient", and "Number of cycle samples" can be changed easily by the operation on the front panel of this instrument. However, do not change them except when the change is unavoidable, because the setting has been adjusted to meet the specifications of the flowmeter combined to this instrument. **: Effectively indicated only when the input pulse has small frequency variation.
