AB270/AB280/AB290 Non-Ferrous Birotor Plus Meter

The Non-Ferrous BiRotor Plus meter is a volumetric fl ow measuring device designed for the accurate measurement of petroleum liquids in aircraft refueling. 

This double case meter combines the rugged durability and long service life of the traditional BiRotor meter with the improved accuracy and pulse output associated with today’s most sophisticated devices. 

Utilizing single or dual outputs, with two non-wetted pickoffs mounted 90° out of phase, the Non-Ferrous BiRotor Plus complies with API Level B pulse output standards. 

Output signals are amplified and shaped by a preamplifier mounted directly on the meter for transmission to accessories such as totalizing counters, digital readout devices, provers and other control equipment and instrumentation. 

The typical application is for aviation fuel measurement where the meter must be of non-ferrous material. This includes fueling and defueling where the meter comes in direct contact with the airplane or helicopter. 

The meter is designed for use on refueling trucks and hydrant trucks/carts. With a maximum operating pressure of 200 psig, the meter meets the SAE specifi cations for hydrant refuelers.
