Coriolis Mass Flow Meter — IZMERKON CM 470

Coriolis Mass Flow Meter — IZMERKON CM 470

The Coriolis flow meter IZMERKON CM 470 is part of a line of equipment for direct mass measurement and eliminates errors that may arise due to fluctuations in density, temperature, or pressure of the working medium.

The device implements the measurement principle based on the Coriolis force, allowing direct determination of mass flow without using indirect volume calculations. This ensures high metrological accuracy and makes the flow meter an optimal solution for industries with increased product accounting requirements.

Features of the IZMERKON CM 470 Flow Meter Model

The key distinction of this equipment is its versatility and resistance to external factors. Coriolis mass flow meters of the CM 470 series have a number of design advantages:

• Direct mass measurement: the result does not depend on changes in viscosity, density, or flow profile.
• Multifunctionality: one device simultaneously measures mass flow, density, temperature, and volumetric flow.
• High accuracy: error ranges from ±0.1% to ±0.2%.
• Reliability: no moving parts in the flow section subject to mechanical wear.
• Wide temperature range: from cryogenic temperatures (-196 °C) to high temperatures (+250°C).

Along with this device, the following similar instruments may also be of interest:

• Vortex Flow Meters VT 470 — measured media: liquid, gas, steam, suspensions.
• Electromagnetic Flow Meters EM 470 — measured media: liquid, suspensions.
• Metal Rotameter RM 470 — measured media: liquid, gas.

General Information about IZMERKON CM 470

The IZMERKON CM 470 devices are suitable for operation in the most challenging conditions. This is the ideal flow meter that handles high-viscosity substances (bitumen, fuel oil, syrups).

Structurally, the Coriolis flow meter consists of a sensor and an electronic converter. The sensor can have various shapes of measuring tubes (U-shaped, M-shaped, and S-shaped), allowing the optimal option to be selected for specific dimensions and hydraulic characteristics of the system. If you need to buy a Coriolis flow meter for working with aggressive chemicals, versions made of Hastelloy C are available.

Principle of Operation of the Flow Meter

The device operates based on the use of the Coriolis force arising in the oscillatory system. Inside the sensor are measuring tubes that are set into vibration by an electromagnetic coil.

When the medium begins to move through the vibrating tubes, inertial forces arise, causing a phase shift (twisting) of the tubes:

1. Detection of shift: special sensors at the inlet and outlet record the time difference of the passage of the extreme points.
2. Mass calculation: the time delay (phase shift) is directly proportional to the mass flow.
3. Density measurement: the frequency of the tubes' resonant vibrations depends on the medium's density — the denser the substance, the lower the frequency.

Thanks to this, the mass flow meter provides the most complete data on the flow condition without installing additional calculators.

Applications of the Coriolis Mass Flow Meter

Oil and Gas Industry

Mass flow meters for liquids are used for tank filling, well flow rate measurement, and component mixing. Direct mass measurement helps avoid disputes since the product mass remains unchanged with temperature fluctuations, unlike volume.

Food and Pharmaceutical Industry

For industries with heightened sanitary requirements, the accuracy and cleanliness of measuring instruments are critical factors. The device is available in a special hygienic version with sanitary connections of the Tri-clamp type (according to order code "SF"). This allows its use in production lines of medicinal products and active pharmaceutical substances.

Water Treatment and Purification Facilities

The Coriolis mass flow meter IZMERKON CM 470 is used here for precise dosing of coagulants, flocculants, and aggressive chemical solutions. Unlike volumetric meters, this device is not sensitive to changes in concentration and viscosity of sludge or activated sludge.

Properties of the CM 470 Flow Meter

When choosing, it should be considered that the price of the mass flow meter is justified by long-term savings on maintenance and the absence of product losses.
