Flowmeters and System solution.



ULTRAmassMKⅡ High pressure type



A high-performance Coriolis flowmeter capable of directly measuring mass flowrate with high accuracy. High accurate measurement is also possible for the purpose of large mass flow measurement.

Product Specifications


● Exceptional accuracy (±0.2% ±zero stability error of reading for liquid service) and high sensitivity (measuring range 1 to 200).
● Accepts both liquid and gas. Measures precisely with small pressure loss over a broad flow range.
● Measures density and temperature accurately in addition to mass flowrate.
● Minimum pockets for the process fluid to stand (in vertical installation) offer ease of cleaning.
● Lightweight and compactly built, yet exceptionally high mechanical strength. The result is ease of handling, installation space saving, and increased process safety.
● Explosionproof construction permits meter installation in a hazardous location.

※1: Miscellaneous: For products conforming to the high pressure gas safety regulations and consult our representative.


This pressure does not represent the withstanding pressure of pressure vessel ratings, but shows 1/4 the pressure of the breakdown test pressure (four-fold pressure test),
accepting a deformed casing, or that in the FEM analysis, whichever is lower (safer level): it actually represents the withstanding pressure below 1/4 the breakdown pressure.

※3: In applications where fluid and atmospheric temperature exceeds 130˚C, select high-temperature service meters.
