MEASUREMENT OF LIQUEFIED NATURAL GAS OR LIQUEFIED

PETROLEUM GAS



This instrument does not have explosion-proof structure. Before

measuring liquefied natural gas or liquefied petroleum gas, be

sure to collect some into a Tedlar Bag. Please measure them in

non-explosion-proof areas.



Gas after a measurement is discharged from the outlet. Use the

instrument in a draft chamber or connect the outlet and draft

chamber or exhaust duct using a tube to discharge the gas.

(1)

Install the instrument in a draft chamber or connect the outlet and draft chamber or

exhaust duct using a tube.

Connect a tube with an inside diameter of 2.5 mm or less to the outlet.

*Tube aren’t included. Please prepare.

(2)

Collect gas to be measured into a Tedlar Bag.

(3)

Set “NG/LPG” for “Meas. Gas”. (Refer to “4.5.2.2 SETTING OF GAS TO BE

MEASURED”.)

(4)

Connect the Tedlar Bag and probe.

(5)

Open the faucet of the Tedlar Bag and press “START” to start a measurement.

Warning

Caution
