For steel mill use
1) When the density meter is attached, adjust again the indication of the flowmeter (5- 3) by
V-11.
2) When the number of bubbles coming out from the pipe A is not constant, adjust it by V-12.
3) Set the computing station to Input / Output status display. If either the indication of “X2
(A-PRESS)” or “X3 (G-PRESS)” is not ”500”, adjust each with the pressure reducing valve
(3-6) and V-16.

Stopping Operations
n
Long Time Stopping
1) Close V-1. To stop standard pressure gas for the steel mill use, close V-4. But when a pump
is attached, turn off the power of pump in advance.
2) When the gas supply is suspended and the burner is extinguished, the lamp “MEAS” of the
calorie detector is lit off and the lamp “ALARM” on.
3) Switch the calorie detector from “SAFE EV” to “RELEASE”.
4) To stop the flow of a town gas , close V-6 and open V-7, V-8. To stop the flow of steel mill
gas, close V-4 and open V-5, V-8. The sample gas in the gas line should be blown off by the
air then the subtle sample gas will be emitted
5) After continuing the blow for 3 to 5 min., turn off the “POWER” switch of the calorie detector.
If the density meter is attached, cut the power supply inside the density meter.
6) Turn off all switches of the switch box.
7) Lastly, close V-14 and stop the air supply.
n
Short Time Stopping
Same as mentioned above, the mode suspends the supply of sample gas only.
If this state is kept on hold, you can skip the warm-up time before another operation starts.
