Coriolis Mass Flowmeters
ALTImass and ULTRAmass meters that measure mass flow, density and temperature directly.

A Coriolis flowmeter measures mass directly and continuously — the one property of a fluid that does not change with temperature, pressure, viscosity or density. The same sensor measures temperature and density at the same time as flowrate, and handles general liquids as well as foods, chemicals, slurries and high-density gases.
The ALTImass Type U is OVAL's all-round high-performance model, with a self-diagnosing transmitter, large display and touch-panel field configuration, suited to extremely low flows and short-duration filling. The ALTImass Type S suits clean processes where fluid tends to build up or must drain quickly, the Type B is a compact model, and the CoriMate II is a low-cost meter with built-in indicator for micro-flows. The ULTRAmass MKII is a general-purpose Coriolis meter, with high-pressure versions up to 120 MPa.
