Marmonix MVF-2200 (MVF2200 / MVF 2200) Flanged Vortex Flow Meter for Liquid, Gas and Steam

The Marmonix MVF-2200 vortex flow meter (also typed MVF2200 or MVF 2200) is a flanged, no-moving-parts meter for liquid, gas and steam lines from DN15 to DN300, rated ±0.75% of reading on liquids and ±1.0% of reading on gas and steam. A bluff body in the SS304 or SS316 meter body sheds vortices at a frequency that rises with flow velocity, and the sensor head counts them. Order it for −20 to +100 °C, +250 °C or +350 °C media and 1.6, 2.5 or 4.0 MPa nominal pressure; the transmitter gives two-wire 4–20 mA, three-wire pulse and RS485, from 24 VDC or a 3.6 V lithium cell. The same datasheet lists flange-card versions for DN15–DN300 and an insertion build for DN100–DN2000. Browse all Marmonix industrial flow meters or compare the MSF-2202 steam flowmeter.

Flange Vortex Flow Meter MVF-2200

Insertion vortex flow meter Marmonix MVF-2200 works based on Carmen and Strouhal relevant spiral produce and on the theory of the flow relationship. As shown in picture, In the meter body vertical insert a triangular prism root namely the happening of the body, when eddies of medium flow through the table body, in triangular prism behind the alternate produce in opposite directions regular karman swirl, its spiral separation and the flow of the medium frequency F speed by sensing head is proportional to the V detected the number of spiral, can measure the flow velocity, again according to the table body mouth.

Flange Vortex Flow Meter MVF-2200 Features

Build points listed for the MVF-2200 body and transmitter:

• Flange & body: integrally forged pieces, it will avoid break down into pieces. 100% SS304 material, we can provide material report.
• Circuit Board: Digital circuit board, anti-most of the supplier use analog circuit board, digital circuit board enjoy the advantages of anti-vibration and anti-interference.
• Flow converter: Distinctive modular design, amateurs can operate, disassemble and assemble easily, it will avoid accident risks.
• welding: adopt the advanced fish scale technology, which makes the welding seam looks nice and smooth.
• Our medium temperature sensor can measure highest temperature around 350℃, normal it is -40~250℃

Case study: choosing the MVF-2200 bore from its datasheet flow table

A vortex meter only reads well while the velocity stays inside its working band, so the bore is chosen from the expected flow, not copied from the pipe size. The MVF-2200 datasheet gives standard and extended ranges per size, quoted for water at 20 °C and for air at 20 °C and 101325 Pa.

Rows from that table that engineers check first:

• DN25: liquid 1.5–12 m³/h standard (0.8–16 extended); gas 8–80 m³/h (8–120 extended).
• DN50: liquid 3–50 m³/h standard (2–60 extended); gas 30–300 m³/h (30–500 extended).
• DN100: liquid 12–200 m³/h standard (6–240 extended); gas 100–1000 m³/h (100–2000 extended).
• DN200: liquid 40–800 m³/h standard (30–1200 extended); gas 400–4000 m³/h (350–8000 extended).

The order of work that follows from the table:

• Convert first: gas or steam flow at line pressure and temperature is converted to the reference condition before it is compared with a row.
• Normal flow in the standard band: the smallest size whose standard range holds both the lowest and the highest normal flow is usually picked; the extended range is kept for short peaks.
• Then the options: medium code (liquid, common gas, saturated or superheated steam), temperature version, pressure rating, and any temperature, pressure or combined compensation, local display or explosion-proof format from the model table.

Checking a selection this way, against the published rows, keeps the meter out of its low-flow region where vortex shedding becomes unreliable.

MVF-2200 vortex meter: buyer questions

Can the MVF-2200 measure saturated and superheated steam?

Yes. The datasheet lists wet, saturated and superheated steam alongside liquid, dry gas and wet gas, with ±1.0% of reading on steam. Temperature, pressure and combined compensation appear as order options.

Which pipe sizes and connections does the MVF-2200 cover?

Flange and flange-card connections from DN15 to DN300, plus an insertion version for DN100 to DN2000. Body material is SS304 or SS316.

What power and signals does the MVF-2200 use?

It runs on 24 VDC or a 3.6 V lithium battery and outputs two-wire 4–20 mA, three-wire pulse and RS485. The housing is IP65 for −25 to +55 °C ambient.
