DISPLAY APPARATUS OF CONVERSION RATE OF GAS

摘要

PURPOSE:To obtain the value of display rapidly and accurately, by constituting a titled apparatus by composing the concentration-output characteristic of both gases preliminarily and actuating a display instrument of conversion rate of the basis of said characteristic at the conversion rate display apparatus at the time of converting liquefied petroleum gas to manufacturing gas. CONSTITUTION:At an apparatus displaying a conversion rate at the time of converting gas to be converted such as liquefied petroleum gas having a property that the thermal conductivity of 100% gas concentration coincides with that of 0% gas concentration into manufacturing gas not having such property, a heat conduction type gas detection element 3 proportionally varying the output value for a conversion rate display instrument 4 with the change of temperature due to contact with the gas is equipped. On this occasion, the concentration-output characteristic on the basis of each air of both gases is so composed that said characteristic of 100% gas concentration coincides with that of 0% gas conecntration, and the apparatus is constituted to actuate the instrument 4 on the basis of the composed concentration-output characteristic.
