Abstract :
BY MEANS of the torque balance telemeter it is now possible to indicate or record with instrument speed and accuracy, the value of such quantities as watts, amperes, volts, temperature, pressure, and flow. These indications may be made up to distances of 100 miles. The value of direct current which is used as the translating means is well within the limit stipulated by the telephone companies. Also, the telemeter automatically compensates for variation in line wire resistance, auxiliary supply power voltage, and variations in tube characteristics.
