High-precision Coriolis flow meters for direct measurement of mass flow, density and temperature of liquids, gases and cryogenic media. From DN01 to DN250 — solutions for any industrial application.
Mass-EXPERT Coriolis mass flow meters are designed to measure the mass flow rate and mass of liquid (including oil) and gas, to determine the volumetric flow rate and volume of liquid, the volumetric flow rate of gas reduced to standard conditions, as well as the density of liquid and the temperature of the working medium.
At all stages — from engineering design to commissioning
Testing at accredited metrological centres
Robust design, self-diagnostics, quality system
For safe operation in any conditions
The Mass-EXPERT mass flow meter is based on the Coriolis effect and consists of two main components: a sensor and a transmitter.
The measuring tube constantly vibrates. If the medium is not flowing, the vibration is symmetrical. The flow of the medium creates a phase shift proportional to the mass flow rate.
Calculated from the natural oscillation frequency of the tubes. When the density of the medium changes, the vibration frequency changes as well. The flow meter determines density from this frequency.
Calculated automatically — from the measured mass flow rate and density of the medium. No additional sensors required.
Measured directly inside the flow meter by a built-in resistance temperature detector. No separate temperature sensor required.
Direct mass flow measurement based on the Coriolis effect: readings are independent of temperature, pressure, density and medium composition
Eliminates the problem of volumetric flow measurement. No need to convert volume to mass — eliminates errors caused by changes in temperature, pressure or density.
For liquids — up to ±0.1%, for gases — up to ±0.5%.
Up to 100:1 — per the type approval description No. 98506-26.
The reading smoothing time is adjustable — the user chooses how quickly the device responds to flow rate changes.
There are no moving parts inside the flow meter, which reduces the probability of failures and simplifies installation. Average service life — 20 years.
Measures flow rate, density, temperature and other parameters simultaneously. One mass flow meter can replace several measuring instruments.
The device reports faults itself, simplifying troubleshooting and reducing downtime.
Mass-EXPERT is not just a flow meter but an exact match to your old device in face-to-face length. We will extend the sensor and use the same connection type — replacement without changing the piping design.
L₁ = L₂ → face-to-face length and connection are identical
We will prepare a tailored quotation for your task: we will match an identical process connection, we guarantee 100% compatibility in face-to-face length

Maximum liquid mass flow rates for Mass-EXPERT flow meters
* As the flow rate approaches the lower limit of the range, zero point stability must be taken into account. It is this stability that determines how realistically the declared range can be achieved in practice.

The Mass-EXPERT Coriolis mass flow meter provides direct measurement of the mass flow rate of liquids and gases. The results are independent of medium density, temperature, pressure and flow velocity distribution.
Four transmitter versions — from the basic ME100 to the ultra-compact stainless steel ME400.
In any configuration you get a high-performance microprocessor, an intuitive interface and built-in self-diagnostics that ensure stable operation and simplify maintenance.
LCD or LED display of your choice with an intuitive interface for fast, convenient configuration and viewing. Parameters can be set and viewed both from the display and remotely via M-link software. The ultra-compact ME400 has no display — it is controlled fully remotely.
Mass-EXPERT — flexible configuration for any task: from the basic transmitter to the advanced one, depending on your project's needs. Cost optimization: we use only the necessary functions — no overpaying for "extra" options.
A basic solution for typical industrial conditions. Wide flow measuring range: for liquids from 1.2 kg/h to 1,740,000 kg/h. Connection diameter and the option to vary the face-to-face length to simplify replacement of the existing flow meter.
For systems with pressure above 10 MPa. Materials resistant to hydrogen embrittlement are used. Design safety margin — 1.5×. Reinforced design for operation at pressures above 10 MPa (≤96 MPa depending on size). High accuracy at low flow rates — increased oscillation amplitude. Support for standard high-pressure connections: UNF female thread, VCO/VCR fittings.
For cryogenic conditions at temperatures from −196 °C to +150 °C. High sensitivity at low flow rates of cryogenic liquids — liquid nitrogen, oxygen, methane. Compact design, extended service life. Operating temperature range per the State Register: −196…+350 °C.
For cryogenic plants at ultra-low temperatures from −255 °C to +150 °C: metering liquid gases — hydrogen, helium, nitrogen, oxygen — across liquefaction, storage and cryogenic refuelling. The range covers liquid-hydrogen temperature (−253 °C). Remote design only: the transmitter is mounted away from the sensor (standard cable length — 3 m) and stays clear of cryogenic temperatures.
Reliable operation at elevated temperatures up to +230 °C. For hot oils, melts, superheated steam. Available in remote design to protect the electronics unit from overheating.
For ultra-high temperatures up to +350 °C. Used in remote design — the transmitter is moved to a safe area. For petrochemical plants and high-temperature reactors.
The choice of bend type depends on operating conditions, process specifics, installation space dimensions and the properties of the measured medium. The right choice ensures maximum efficiency, safety and service life of the flow meter.

For media that require a constant temperature: bitumen, sulfur, paraffins, fuel oils.
The isothermal jacket is a heat-insulating shell for the flow meter sensor, through which a heat transfer medium (steam, hot oil) is passed. It is designed for flow measurement of media sensitive to temperature changes: bitumen, sulfur, paraffins, fuel oils, tars, resins, polymers.
Why it matters:
Result: stable temperature → constant viscosity → accurate and reproducible measurements within the flow meter's rated accuracy.
