Avery-Hardoll

Avery-Hardoll flowmeters are precision-made positive displacement liquid measuring instruments manufactured by Silea Liquid Transfer of Ozzano Emilia, Italy, which acquired the Avery-Hardoll product line in 2021. The brand's heritage reaches back to 1932, when simplicity of design and construction together with sustained accuracy led to the widespread use of Avery-Hardoll meters, including the BM Series meters and MASTERLOAD.iQ electronic registers, on aviation refuelling vehicles throughout the world.

With proven measurement accuracy as good as 0.05 percent, Avery-Hardoll meters remain unmatched in maintaining accurate fluid measurement, and the proprietary design remains an industry benchmark. The range also includes the DM Series flowmeters and the IPV valve, making it ideal for installation on metering skids across oil and gas applications. Parent company Silea Liquid Transfer also manufactures loading arms for railway tankers and trucks, floating suctions for tanks, folding stairs, and positive displacement rotary vane pumps.
