The Brodie Birotor Meter is a positive displacement meter utilized in the most demanding applications requiring accuracy, long life and ruggedness. The legacy Birotor is available in two configurations, integral mechanical registration or electronic pulse output.

The mechanical meter utilizes a gear train located outside the measuring unit chamber to transfer mechanical rotation of the rotors to a mechanical or electronic register for totalization of liquid throughput.

For P-Style (Pulse output) units, a pulse verification gear located outside the measuring unit chamber conveys mechanical rotation of the rotors to the sensor and to the electronic register for totalization of liquid throughput.
