Abstract:
1. The heating value meter ( 1 ) for gases, comprising an outer mantle ( 10 ) with thermostatically controlled heating and with at least one air inlet ( 103 ) for introduction of air and at least one as inlet ( 105 ) for introduction of test gas or for introduction of calibration gas, and a measuring block ( 11 ) placed inside the outer mantle ( 10 ), characterized in, that outer mantle ( 10 ) is cylindrical, it is equipped with a heating mantle ( 101 ) on its outer surface and its bottom part contains an outer sensor ( 102 ) of an first electrical remote thermometer of the outer thermostatic apparatus ( 2 ) placed axially in the wall, and a measuring block ( 11 ) is also cylindrical with an axial through-hole ( 113 ), it is located coaxially inside the outer mantle ( 10 ) and its upper part is equipped with an outlet ( 104 ) and an axially inserted internal sensor ( 112 ) of a second electrical remote thermometer of the internal thermostatic apparatus ( 3 ), while the heating mantle ( 101 ) and the outer sensor ( 102 ), and also the electrical heating block ( 111 ) and the internal sensor ( 112 ), are interconnected via the outer and internal thermostatic apparatus ( 2 , 3 ), adjusted for maintaining of a constant temperature value by regulation of an electrical input to the electrical heating block ( 111 ), or of the electrical input to the heating mantle ( 101 ), wherein the measuring apparatus ( 31 ) of the electrical input of the heating block ( 111 ) is connected to an electric lead of the electrical heating block ( 111 ).
