LEMIS Process – Company Profile

About Us

Founded in 1988, LEMIS Process is an international manufacturing and service organization specializing in the development of sophisticated measuring instrumentation for the process industry.

Our journey began with the portable density meter D-921, the first instrument of its kind capable of measuring density and temperature directly in tanks without sampling. Since then, we remain the only global manufacturer of similar portable density meters, trusted by petroleum companies and beyond.

Over the years, we have expanded our portfolio and expertise:

• 1994 – First portable density meters supplied to petroleum companies

• 1996 – Launch of second-generation DM-230 portable submersible density meters

• 2002 – Achieved ISO 9001:2000 certification by Det Norske Veritas

• Today – Offering a full range of Density, Viscosity, Flow, and Level solutions
