Home > Temperature > Coriolis Mass Flow Meter
The Heinrichs TMU high performance Coriolis mass flow meter distinguishes itself from the competition because we are able to achieve higher flow rates and mass flow measurements in larger line sizes than other mass flow meter providers. With the TMU, we have achieved accurate mass flow measurements up to 2,200 metric tons per hour in line sizes up to 16 inches.
It has a very accurate, rugged design built for mass flow measurements of liquids and gases in most chemical, petrochemical, oil and gas applications.
Mass flow, density and temperature are simultaneously measured, and volumetric flow is computed from these parameters.
The flow meter’s wetted materials (fittings and measuring tubes) are available in 316L stainless steel or Hastelloy® C-22 with other materials available on request.
There are no moving parts to wear out, and the measuring tubes and sensors are protected by a very rugged, all-welded housing. The TMU employs a highly effective measuring tube de-coupling system that virtually eliminates errors caused by piping-induced vibrations and stresses. This allows the flow meter to provide very accurate mass flow measurements in the most demanding applications.
The TMU is the clear choice if you require mass flow measurements of very high flows in large line sizes.
The Mass Flow Meter model TMU utilizes the Coriolis principle of operation to measure mass flow. Density and temperature are simultaneously monitored and volumetric flow is additionally calculated with these parameters. The TMU Series is available with a direct mounted transmitter or in a remote mounted configuration. The unit can be used to meter nearly all liquid or gaseous media and was especially designed to operate in many standard applications. It is applied in many different industrial branches. The TMU Series is also used for precise dosing as well as in loading and unloading applications. Approvals for service in custody transfer (fiscal metering) applications are also available.
