Programming (cont.)
• Example 1: Program a system consisting of Model 213 Flow Meter, Model 284 Transmitter.
Total display engineering units = xxxxxxxxx.x gal (set D.P. in sub menu 25)
Rate display engineering units = xxxx.xx gpm (set D.P. in sub menu 35, units in sub menu 37)
K-factor = 111.373 pulses/cc
Sub Menu 11
111.373 pulses/cc x 3785 cc/gal = 421,547 pulses/gal
K-factor (with decimal place) = 421,547 x 0.1 = 42,155
Program sub menu 11 with the value 42,155
[ Clear ] [ 4 ] [ 2 ] [ 1 ] [ 5 ] [ 5 ] [ Enter ]
Sub Menu 12
Rm =
60 sec/min x 0.1 (total decimal)
0.01 (rate display decimal)
Program sub menu 12 with the value 600
[ Clear ] [ 6 ] [ 0 ] [ 0 ] [ Enter ]
• Example 2: Program a system consisting of Model 241 Flow Meter, Model 284 Transmitter.
Total display engineering units = xxxxxxxxx.x kg (set D.P. in sub menu 25)
Rate display engineering units = xxxxx.x kg/hr (set D.P. in sub menu 35, units in sub menu 37)
K-factor = 402.9 pulses/liter
Specific gravity = 0.84 at process temperature *
Sub Menu 11
402.9 pulses/liter
0.84 kg/liter
K-factor (with decimal place) = 479.64 pulses/kg x 0.1 = 47.964
Program sub menu 11 with the value 47.964
[ Clear ] [ 4 ] [ 7 ] [ < ] [ 9 ] [ 6 ] [ 4 ] [ Enter ]
Sub Menu 12
Rm =
3600 sec/hr x 0.1 (total decimal)
0.1 (rate display decimal)
Program sub menu 12 with the value 3600
[ Clear ] [ 3 ] [ 6 ] [ 0 ] [ 0 ] [ Enter ]
* Accurate mass displays can be obtained with the 120 if the process temperature remains
relatively constant. For applications where the temperature varies, better accuracy will be
obtained with a temperature compensated Max Indicator.
