Title:
流量計における温度計測回路
Document Type and Number:
Japanese Patent JP4274385
Kind Code:
B1
Abstract:
A value of a line-to-line resistor (24) is determined by subtracting a resistance value determined as a product of a voltage ratio based on divided voltages and a value of a reference resistor in a non-conductive state between a second electric wire (26) and a third electric wire (27) from a resistance value determined as a product of a voltage ratio based on the divided voltages and the value of the reference resistor in a conductive state therebetween. Once the value of the line-to-line resistor (24) is determined, it becomes possible to determine a compensated resistance value related to temperature.
