Jual Flow Meter Avery Hardoll BM 450 Series

Avery Hardoll BM Series flowmeters are precision made, positive displacement, liquid measuring instruments that maintain the higest level of accuracy over a lifetime of operation. Simplicity of design and accuracy has resulted in the Avery-Hardoll BM Series meters to being the most preferred meters by aviation fueling operators and airlines in internatonal markets.

BM Series bulkmeters are manufactured in three basic sizes with different ratings identified by a series number.

The series numbers, sizes, flow rates, and a brief description of each series of meter are shown below.



Serial Number : BM450

Manifolds : 3 inches, 76 millimeters

Flow Rates : 45– 450 Imperrial Gallons, 200 – 2050 liters

General Description : Double Capsule Meters



  • The BM Series bulkmeters consist of three main assemblies: the manifold, body assembly and rotor assembly
  • The higher rating of the larger meters is achieved by bolting two or three body capsules together and fitting double or triple rotor assemblies 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

Avery-Hardoll bulkmeters can be used on all petroleum products of all viscosities. However, there is an increase in pressure drop with more viscous fuels, which under normal circumstances will limit the maximum flow rate obtainable. It is recommended 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 when 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 suggested that the pressure drop through the meter should not exceed 10 psi (0.7 bar) for continuous running at maximum 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.
