从United States供应商批量进口Alia Variable Area Flowmeter

The AVF250 series variable area flowmeter from Alia Group Inc operates on the classic float-in-tapered-tube principle, where fluid upward velocity balances the float's weight to indicate volumetric flow rate. This mechanical meter requires no external power for local indication, making it suitable for installations without instrument air or electrical supply redundancy. The tapered borosilicate glass or metal tube construction allows direct visual reading of flow against a printed scale.

Float materials commonly include stainless steel, PTFE-coated aluminium or ceramic, selected for chemical compatibility and density relative to the measured fluid. Variable area flowmeters of this type typically achieve accuracy of ±1% to ±2% of full scale for gas applications, and ±1.5% to ±2.5% for liquids, depending on Reynolds number and installation orientation. The AVF250 is described as compact, suggesting a short-stroke design with reduced overall length compared to traditional glass tube models, beneficial for crowded skid or panel mounting.

Automotive manufacturing, chemical dosing skids and water treatment plants represent typical end-user environments where this flowmeter class is deployed. For viscous or dirty fluids, the absence of internal obstructions beyond the float itself reduces clogging risk compared to orifice or turbine alternatives. Buyers should confirm with Alia Group Inc whether the AVF250 is rated for pulsating flow, and whether a transmitter option with 4-20 mA or switch output is available for remote monitoring integration.

Alia Group Inc is registered at 113 Barksdale Professional Center, Newark, Delaware 19711, United States. The supplier profile indicates an imported tier classification with harbour trust level, reflecting marketplace registration rather than third-party factory audit. No response data is recorded, meaning buyers should not rely on platform messaging alone and should pursue direct email or telephone contact for technical and commercial discussions.

The listing provides no information about company founding date, employee count, production capacity, or existing customer references. Delaware incorporation is common for US holding companies, so the actual manufacturing site of the AVF250 series may differ from the registered office. Prospective buyers should request a supplier capability assessment, including whether Alia Group Inc designs and assembles the flowmeters or sources them under private label arrangement from an original equipment manufacturer.
