The Torquemeter has been used reliably by the chemical industry for quite awhile as well as in LNG facilities. It has proven to be economically viable in measuring the output power and also allows the operator to control the balancing and possible deterioration in the turbine.

The torquemeter has been used to monitor problems that could arise in compressor fouling and turbine fouling so that operators can take corrective actions when problems arise. The torquemeter can also collect and store data to provide engineers with information to analyze loads on the drive train over time and also can be used to determine if the facilities can operate at a maximum continuous speed of the compressor and turbine can at minimal costs.

The torquemeter for the turbine works by measuring the twist of the coupling spacer made with integral teeth. The system has multiple pickups in the form of internally toothed rings. As the shaft rotates, its teeth cut the flux and generate a sinusoidal voltage in each coil. The torque required to twist the shaft through one tooth pitch would correspond to a 100% phase displacement. An electronic readout device then converts the speed and phase measurements into torque.
