About Digmesa
Digmesa AG develops, designs and manufactures precision flow meters for professional applications – from the first FH flowmeter developed in 1983 to a broad product range with Hall-effect sensors, Venturi meters and displacement meters. The measuring devices are used in coffee and espresso machines, beverage and vending machines, medical technology as well as water treatment and filtration, measuring flow rates from 0.03 to over 25 l/min at pressures up to 20 bar. Depending on the application, the housings are made of lead-free brass, stainless steel or plastics such as PBT, PVDF, PEEK and Arnite; since the acquisition of Polyform Kopp AG in 2013, the company has produced plastic components in its own injection-molding department. In addition to its standard product line, Digmesa develops custom flow solutions – from prototype to large-scale production – on automated production lines at its headquarters in Ipsach (Switzerland). The company distributes its products worldwide via international distributors.
