ABSTRACT:
A temperature compensator for a fluid flow meter, e.g. an industrial gas meter, has a temperature sensing element which contacts the flow of fluid being metered. The temperature sensing element adjusts the position of a cam surface so as to limit the arc of travel of an oscillating cam striker element in accordance with the temperature of the fluid. The cam striker element is driven in both directions by means operatively associated with a driving element driven by the fluid flow. A recorder records the distance travelled by the cam striker element in a given time, so as to provide a reading of temperature compensated fluid flow.
