There are following measuring system available or could be used on LPMT:
| System | Obtained results | Description |
| Mass flow measurement |
Values of steam and water mass flows going through different control sections such as inlet, extraction and outlet | Either calibrated nozzles or weighting system |
| Torque measurement |
Values of force on the lever of water brake | Force is measured by dynamometers |
| Thermodynamic parameters | Static pressures and temperatures along flow path, droplet diameters and wetness concentration | About 200 sensors could be used for static pressure measurement (the measuring scheme is "one tapping-one line-one sensor" and about 20 thermocouples are available on test bench. Special optic devices developed in CKTI could do wetness measurements |
| Aerodynamic parameters | Flow velocity components and flow angles | The test bench outer casing has special places for aerodynamic probes installation. Probes are used for flow path traversing |
| Vibration and structure mechanical parameters |
Displacements, clearances, blades and shafts oscillation characteristics | The different types of sensors are used (such as inductive, whirl-current or strain gage) |
The calibration of instrumentation are performed by Mendeleev Russia National Me
trology Center (Mendeleev Institute).
