Vortex Flowmeter — IZMERKON VT 470

Vortex Flowmeter — IZMERKON VT 470

For quality flow control in industrial systems, equipment is required that can operate under high temperatures and pressures while maintaining accuracy. One such solution is the IZMERKON VT 470 vortex flowmeter. This device is a reliable tool for measuring the flow of various media: from clean water to superheated steam and aggressive gases.

If you need to request additional technical documentation for the product or require consultation, contact the specialists at "Izmerkon". They will help select the optimal configuration for specific production tasks.

The VT 470 series devices are universal units designed for insertion mounting directly into the pipeline. Unlike immersion models, this vortex flowmeter provides higher accuracy because it represents a single measuring section, assembled and calibrated at the factory.

Features of IZMERKON VT 470

1. Multiparameter measurement. The device (version with pressure and temperature compensation) can simultaneously measure flow, temperature, and pressure. This allows automatic calculation of mass flow and volumetric flow normalized to standard conditions.
2. No moving parts. Mechanical wear is eliminated, significantly extending service life and increasing the calibration interval.
3. Wide temperature range. The standard type operates with media up to +250°C, and the high-temperature type up to +350°C.
4. Variety of materials. The flow part made of SS304 or SS316 steel allows the device to be used in chemically active media.

General Information about the Device

IZMERKON VT 470 is a classic insertion flowmeter installed on pipes with diameters from 15 to 300 mm. It is ideal for integration into automated systems due to support for RS485 Modbus and HART protocols. The device can be supplied in a compact design, where the electronic unit is mounted directly on the measuring section, or in a remote design for cases where access to the measurement point is limited or the medium temperature is too high.

Principle of Operation of the Flowmeter

The device operates based on the effect discovered by Theodore von Kármán. Inside the flow channel of the flowmeter, a bluff body (prism) is installed. When the flow passes around this obstacle, a chain of vortices forms behind it.

The operation of the vortex flowmeter is based on a simple relationship: the frequency of vortex shedding is directly proportional to the flow velocity of the medium. A special piezoelectric sensor detects the frequency of pressure oscillations occurring behind the bluff body. Then the electronics convert this frequency into volumetric flow. Since the geometry of the flow part is constant, such a vortex flowmeter for gas or liquid maintains accuracy over many years.

Applications of the Vortex Flowmeter

The versatility of the device makes it in demand in almost all industries where accurate measurement of liquid, gas, and steam flow is required.

Vortex Steam Flowmeters in Power Engineering

The main challenge is that steam constantly changes its density under the influence of temperature and pressure. A conventional steam flowmeter will give a large error with the slightest cooling of the pipe or pressure surge.

The VT 470 vortex flowmeter series solves this problem by adapting to the specific state of the medium:

• Saturated steam. In this state, temperature and pressure are strictly dependent on each other. The device only needs to measure one parameter to instantly determine density and provide an accurate mass flow.
• Superheated steam. Here the dependency disappears: temperature and pressure can change independently. VT 470 simultaneously reads data from its own pressure and temperature sensors. This ensures accuracy even in unstable CHP plant operating modes.

Vortex Flowmeters for Liquids and Water

Although electromagnetic models are often used for water, in some cases a vortex water flowmeter is a more justified choice. For example, when working with demineralized water or condensate, where the medium's electrical conductivity is too low. Vortex liquid flowmeters are also indispensable for monitoring light oils and solvents.

Properties and Technical Specifications

To choose and buy a vortex flowmeter, it is necessary to consider the technical specifications:

• Accuracy: ±1.0%
• Pressure: up to 4.0 MPa (higher pressure on request)
• Output signals: 4-20 mA current loop, pulse output.
• Power supply: 24V DC, 220V AC, 3.6 V from solar battery, 12-30 V (DC) or power from a 3.6 V lithium battery.

Where to buy the product and what determines the price?

The price of the vortex flowmeter is formed based on several factors: pipeline diameter (DN), the need for built-in temperature and pressure sensors, as well as the body material. The IZMERKON VT 470 insertion models provide an optimal balance of cost and functionality.

If the task is to buy a gas flowmeter with a warranty and subsequent service, contacting the manufacturer directly will be the best solution. Having a warehouse in Saint Petersburg significantly reduces equipment delivery times to the site.

The IZMERKON VT 470 vortex flowmeter is an investment in transparency and production efficiency. Thanks to high long-term stability of readings and no need for frequent maintenance, the device quickly pays off.
