History

In 1937 the Cav. Rodolfo Rinaldi based in Sesto San Giovanni a company devoted to the production of equipment for autogenous welding, hence the acronym ASA. But the pioneering spirit and innovative ideas of the founder lead him soon to undertake a new direction: the measurement of fluid flow.
In 1947, ASA is the first Italian company that manufactures and sells variable area flowmeters glass tube for liquids and gases, otherwise known as Asameters (registered trademark).

The range of flowmeters grows. Metal tube flowmeters are placed on the Italian and international markets. They are flow indicators equipped with pneumatic and electronic transmitters suitable for critical application in terms of performances.

At the Museum of Science and Technology “Leonardo Da Vinci” in Milan, opened the hall GISI (Group Companies Industrial Instrumentation), divided into a large group of instruments for measurement and control, which are used for the automation of industrial plants. Under the heading “Flow measurement” there is an Asameter presented with the following caption: “Volumetric meter for nitric acid with flow indicator and pneumatic transmitter, designed and manufactured by Asa Cav. Rodolfo Rinaldi in Sesto San Giovanni. ”
(Museum of Science and Technology).

Eng. Ilo Rinaldi, son of the founder, took over the management of the Company. In order to develop new product lines, he decided to open a new manufacturing plant in Grumello del Monte, about 60 km far from the historical site in Sesto San Giovanni. In this period was born the production of electromagnetic inductive flowmeters for measurement of conductive fluids.

Eng. Rinaldi with great entrapreneurial courage and forward-looking mind expands ASA production area up to 3,000 square meters and 5,400 square meters outdoors, where it develops part of the impressive facility for calibration of electromagnetic inductive flowmeters.
From the production point of view, these are the years of a new era for ASA. Eng. Rinaldi gives the company a strong signal by introducing innovative production processes and automatic machines of the latest generation. A new concept of industrial serial production makes its way on the factory.

These are the years of the third generation which allows ASA to achieve:
– Quality System Certification according to UNI EN ISO 9001:2000
– ATEX certification of the measuring series C and G / 38-/39 Ex i (certificate CESI 04 ATEX 067X, marking II1GD II2GD and EEx ia IIC T6 IP65 T85 ° C, II 1 GD and II2GD c II T6 IP65 T85 ° C)
– CESI Notification for its Quality Management System according to the UNI EN ISO 9001:2000 and EN 13980:2002.
