3) Turn the switch “SAFE EV” of the calorie detector to “RELEASE”. The solenoid valve of the
gas line opens and the alarm is released.
4) Adjust the flowmeter (3-3) to approx. 10L/min by using the pressure reducing valve (4-1)
and V-13. The pressure gauge (3-2) indicates 8 to 18 kPa.
5) Adjust the pressure gauge (3-5) to approx. 3 kPa. by using the pressure reducing valve (3-
4).
6)
When a density meter is attached, adjust the throttle valve of the flowmeter (5-3) to 0.5 to 1 l/min.
7)
Set the indication of the computing station to Input/Output status display and check X3 (G-PRESS).
8) Adjust by pressure reducing valve (3-6) so that “X3” indicates “500”. When the value on the
pressure gauge (3-5) deviates from about 3 kPa, repeat the procedure (5), then conduct the
adjustment.
9) When the adjustment is completed, close V-8, V-7, separate the one touch coupler (2-5),
and open V-6.
10) Set the “SAFE EV” switch of the calorie detector to “SET”.
n
For steel mill use
1) Close V-4, connect the one touch coupler (2-5) and open V-5 and V-8.
2) Set the switch “SAFE EV” of the calorie detector to “RELEASE”. The solenoid valve of the
gas line opens and the alarm is released.
3) Adjust the flow rate of the flowmeter (4-2) to about 10 l/min by using the pressure reducing
valve (4-1). The pressure gauge (3-1) indicates approx. 6 kPa.
4) When the density meter is attached, adjust the flowmeter (5-3) to 0.5 to 1 l/min by using
V-11.
5) Adjust, by using V-12, the number of bubbles that come out of pipe A of the pressure
regulating pot (3-4). The number of bubbles has to be 3 to 6 pcs/sec. However, if no bubbles
come out, when low calorie gas is being used, open V-12 fully,
6) Set the indication of the computing station to Input/Output status display and check X3
(G-PRESS).
7) Adjust the pressure to “500” by using the pressure reducing valve. “X3” the pressure
reducing valve (3-6), adjust the indication “X3” to become “500”. When the number of
bubbles from pipe A fluctuates, adjust the number by using V-12, then carry out the
adjustment.
8) When completing the adjustment, close V-8 and V-5. Separate the one touch coupler (2-5),
and open V-4.
9) Turn the switch “SAFE EV” of calorie detector to “SET”.
