Abstract

A rotor meter comprises a housing that accommodates two rotatable rotors. Gas flowing through the housing causes the rotors to rotate. One of the rotors 11 accommodates a coil 25 and a transmitter (formed by a coil 27 with a ferromegnetic core 29) connected to this coil 25, which transmitter sends a signal the moment a current starts flowing through the coil. The latter occurs if the rotor meter 1 is manipulated by holding a strong permanent magnet against the housing 3. This strong permanent magnet restrains the rotation of the rotors, but at the same time a current starts flowing through the coil. A magnetic sensor 31 switches when a certain field strength of the magnetic field generated by the transmitter is monitored. The signal from the magnetic sensor 31 is subsequently processed by a microprocessor 33 and then recorded in a time-related manner in a memory 37. Based on this recording it is possible to demonstrate manipulatory activity.
