Avery-Hardoll BM Series flowmeter are precision made, positive displacemnet, liquids measuring instruments that maintain the higest level of accuracy over a life time og operation. Simplicity of design and accuracy has resulted in the Avery-Hardoll BM Series meters to being the most preferred meters by aviation fueling opeartors and airlines in international markets.
BM Series bulkmeters are manufactured in three basic sizes with different ratings indentified by a series number.
The series numbers, sizes flow rates and a brief description of each series of meter are shown below.
Types Of Bulkmeter
Serial Number : BM 650
Manifolds : 4 Inches, 102 millimeters
Flow Rates : 65- 650 Imperrial Gallons, 300-3000 liters
General Description : Triple Capsule Meters
Bulkmeter Main Components
- The BM Series bulkmeter consist of three main assemblies the manifold, body assembly and rotor assemby
- The higher of the larger meters is achieved by bolting two or three body capsules together and fitting double or triple rotors asemblies with a larger manifold to suit
- A calibrating mechanism and mechanical register are also attached to the front end cover
- The calibrating mechanism can be replaced by a front cover incorporating a pulse transmitter when required for electronic systems, such as MASTERLOAD II or MASTERLOAD III registers

Viscous Products :
Avery-Hardoll bulkmeter can be used on all perroleum product of all viscosities. however three is an increase in pressure drop with more viscous fuels, which under normal circumstances will limit the maximum flow rate obtainable. It is recommende that the pressure drop through a bulkmeter should not exceed 15 psi ( 1 bar), above which the load on the bearings will start to cause wear. Consequently ehen using products with viscosities above 100 centistokes (at operating conditions), it is necessary to reduce the maximum permitted flow rate. As a guide it is susgested that the pressure drop through the meter should not exceed 10 psi (0.7 bar) for continuous running at amximum speed or 15 psi (1 bar) for continuous running at half speed. The low pressure drop for the BM Series of Avery-Hardoll bulkmeters is displayed on the left.
