Submersible Vortex Flowmeter — IZMERKON VT 450

Immersion Vortex Flowmeter — IZMERKON VT 450

For precise flow control in industrial conditions, tools combining reliability and data processing accuracy are required. One such solution is the IZMERKON VT 450 vortex flowmeter. This flowmeter is designed to measure the flow of a wide range of media: from dry saturated steam to technical gases and liquids.

If you need to request additional technical documentation for the product or require consultation, IZMERKON specialists are ready to provide complete information and assist in selecting a configuration tailored to a specific technological process.

The VT 450 flowmeter is a versatile device indispensable on large diameter pipelines (from DN80 to DN2000). Unlike insertion models, the installation of the immersion version is simpler: instead of cutting a pipe section between flanges, it is enough to insert one flange with a nozzle into the pipeline wall. This reduces the amount of work, installation costs, and materials.

Operation of the Vortex Flowmeter: Physics of the Process

The device operates on the principle of forming stable vortices in the flow of liquid or gas when flowing around the measuring element. This effect is actively used in vortex flowmeters. Inside the flow part or at the end of the immersion probe, a special element is installed — a bluff body, usually prism-shaped. As the medium flows around this element, alternating vortices form behind it, the frequency of which is proportional to the flow velocity and is used to calculate the flow rate.

Vortex Flowmeter for Steam

One of the most challenging tasks is accounting for heat carriers. The VT 450 series vortex steam flowmeter handles this task thanks to its built-in compensation function. There are two main types of steam requiring control:

1. Saturated steam. Here, measuring either temperature or pressure alone is sufficient to calculate density.
2. Superheated steam. Requires simultaneous monitoring of both temperature and pressure, as these parameters can change independently.

Measured Media

The IZMERKON VT 450 vortex flowmeter effectively works with the following media:

• Technical gases: compressed air, nitrogen, oxygen, argon, carbon dioxide.
• Liquids: technical and demineralized water, condensate, light oils, and chemical solutions with low viscosity.
• Steam: saturated and superheated steam.

Applications

The universal design and absence of moving parts make the IZMERKON VT 450 in demand in industries with high reliability requirements.

Energy and Heat Supply

In thermal energy generation and distribution systems, steam accounting is a priority task. The VT 450 vortex steam flowmeter handles it better than other device types for several reasons:

• Accounting for saturated and superheated steam: The device operates correctly at temperatures up to +350 °C.
• Leak detection: High sensitivity allows timely detection of losses in pipelines.

Oil and Gas and Chemical Industry

The vortex liquid and gas flowmeter is in demand here for the following tasks:

1. Accounting for associated petroleum gas (APG): Stable operation under changing gas composition conditions.
2. Transportation of nitrogen and carbon dioxide: Control of inert gases used to ensure explosion safety at facilities.

The immersion vortex flowmeter is especially convenient on wide flare lines and main pipelines where installing a flanged device is economically impractical.

Water Utilities and Water Treatment Systems

Although electromagnetic models are often chosen for clean water, the IZMERKON VT 450 vortex water flowmeter is indispensable when it comes to:

• Technical and demineralized water: Where the medium's electrical conductivity is too low for magnetic sensors to operate.
• Condensate: High condensate temperature does not interfere with vortex technology.
• Wastewater without large inclusions: The device works effectively on treated effluents in large diameter pipes.

Food and Pharmaceutical Industry

The vortex flowmeter is actively used on auxiliary lines. This may include steam supply for equipment sterilization or cleaning tanks with hot water and detergent solutions.

Features of IZMERKON VT 450

Advantages of the immersion type:

• Installation cost savings: no need to dismantle a pipeline section or use heavy lifting equipment.
• Minimal resistance: the probe occupies only a small part of the pipe cross-section, practically not creating a pressure drop.
• Versatility: the same sensor can be configured for different pipe diameters within its range.

Technical Specifications and Properties

For reliability in harsh operating conditions, the housing and primary converter of the IZMERKON VT 450 are made of steel (standard SS304, optionally SS316). This makes the vortex liquid flowmeter resistant to corrosion and mechanical wear.

Key parameters:

• Temperature range: standard version from -40 to +250 °C, high-temperature version — up to +350 °C.
• Pressure: up to 1.6 MPa for submersible models.
• Accuracy: ±1.5%.
• Output signals: standard 4-20 mA current loop, pulse output, digital protocols RS485 Modbus or HART.
• Power supply: 12-30 V DC, 220V AC (only with remote flow computer), powered by 3.6 V lithium battery.

How and where to order the IZMERKON VT 450 flowmeter?

The price of vortex flowmeters is formed based on several factors: pipeline diameter, the need for built-in temperature and pressure compensation, type of design (compact or remote).

Submersible IZMERKON VT 450 models are initially a more budget-friendly solution for large diameters compared to competing technologies. In addition, having our own warehouse in Saint Petersburg allows us to reduce delivery times and optimize logistics costs.
