4” BiRotor APL

The BiRotor Meter is a positive displacement meter utilized in the most demanding applications requiring accuracy, long life and ruggedness. 

The electronic “P” Series meter configuration features a sealed measuring chamber with one reluctance type electronic sensor. 

The sealed electronic sensor transmits amplified signals to local or remote instruments. A second optional sensor is available to allow dual channel pulses that are 90 degrees electrically out of phase.

The Mechanical BiRotor’s accuracy is attained by the unique BiRotor design which features two finely balanced rotors. 

An adjustor, incorporated on the meter, is used to assure maximum accuracy within the meter’s flow range (Mechanical Only).

There is no metal to metal contact between the rotors and the measurement chamber. The meter is therefore extremely durable.

The rotors, bearings and timing gears are the only moving parts. Maintenance requirements are the lowest in the industry. 

In addition, materials incorporated within the meter assembly are selected specifically for a wide range of petroleum and industrial liquid applications.
