Avery Hardoll Flow Meters

Avery-Hardoll flowmeters are precision made, positive displacement, liquid measuring instruments that maintain accurate metering over long periods of operation. Since 1932, simplicity of design and construction together with sustained accuracy has led to the widespread use of Avery-Hardoll meter products on aviation refueling vehicles throughout the world.

BM Series Meter

Avery-Hardoll bulk meters are precision made, positive displacement, liquid measuring instruments, which maintain accurate metering over long periods of operation. Our BM Series meters range from flow rates of 25 gpm (115 lpm) to 850 gpm (3870 lpm). Simplicity of design and construction together with sustained accuracy has led to the widespread use of these meters on aviation refueling vehicles, in oil terminals throughout the world and also as master meters for use in calibration.

CM Series Meter

Avery-Hardoll bulk meters are precision made, positive displacement, liquid measuring instruments, which maintain accurate metering over long periods of operation. Our CM Series meters range from flow rates of 22 igpm (100 lpm) to 1,200 igpm (5,500 lpm). These meters are are suitable for use in distribution depots and aviation refueling vehicles. 

DM Series Meter

The Avery-Hardoll Steel Bulk meter is specifically designed to meet the rigorous demands of the modern tank truck loading depot. It provides the highest level of repeatability and accuracy combined with minimal down time for service, without the inconvenience and cost of double casting. The Avery-Hardoll Bulk meter positively measures fluid volume with minimum scope for error and with minimal effect from pressure variations, temperature change or turbulence from nearby valves or bends, etc. 

MASTERLOAD II™

The Avery-Hardoll MASTERLOAD II™ is a powerful and versatile microprocessor based electronic controller.  The unit is capable of enhancing the performance of most makes of positive displacement and turbine meters. MASTERLOAD II™ is an intrinsically safe system, ideal for use in Category 2 hazardous areas.  The system is comprised of a pulse transmitter mounted on the meter, a display unit giving readouts of batch volume, flow rate, and a totalizer.

MASTERLOAD III™

MASTERLOAD III™ is a dual microprocessor-based electronic meter register for class 1, div 1, zone 2 hazardous areas. Its primary functions include configuring the meter system to the properties of the metered liquid, interfacing with electronic components of the fuel system, and performing either wired or wireless custody transfer reporting functions. MASTERLOAD III™ is FlightConnect® ready to transform aviation fueling operations from manual paper driven operations to an automated, wireless, data driving enterprise with over 20 reportable fueling data points delivered automatically to back office accounting and control software.

The Slipstream™ Density Measurement System (SDMS)

The Slipstream™ Density Measurement System (SDMS) is an add-on density measurement system for the Liquid Controls and Avery-Hardoll Flowmeters. The SDMS re-routes fuel from the outlet side of the meter through the densitometer and back into the outlet side of the meter. The Densitometer measures the density of the fuel throughout the duration of a fueling and sends real-time density measurements to the LectroCount® LCR 600 electronic or MASTERLOAD III registers.
