Overview

The reference standard for conductive-liquid flow

The NT-VMF electromagnetic flow meter measures the volumetric flow of any electrically conductive liquid, from clean drinking water to aggressive acids and abrasive slurries. Because measurement relies on Faraday's law of induction rather than a mechanical element, there are no moving parts inside the bore: nothing to wear, nothing to obstruct flow, and nothing to maintain.

An unobstructed bore makes it ideal for liquids carrying solids, fibres or sediment, where turbines and orifice plates clog. Liner and electrode materials are selected to match your media, six liners from economical hard rubber to chemical-grade PTFE and PFA, and six electrode alloys from standard 316L up to tantalum for nearly any corrosive.

TÜRKAK Calibration Assurance

Every meter is calibrated on our ISO/IEC 17025:2017 accredited rig (AB-0354-K) at ±0.27% uncertainty before dispatch, a traceable, internationally recognized certificate ships with the instrument.

Working Principle

Faraday's law of electromagnetic induction

Field coils above and below the bore generate a magnetic field across the pipe. As a conductive liquid flows through it, a voltage is induced proportional to the flow velocity. Two electrodes set flush in the pipe wall pick up this voltage and the transmitter converts it to volumetric flow.

Because the bore is completely clear, there is no pressure loss, no obstruction and no part to wear, measurement stays accurate for years, even on dirty or fibrous liquids.

Where & How It's Used

Proven across the process industries

Water Treatment

Raw-water intake totals, filtration line monitoring and chlorine-dosing control, feeding SCADA over 4–20mA or Modbus.

Wastewater

Inlet flow, aeration feed and sludge pumping. The clear bore handles solids, fibres and grit with zero clogging risk.

Municipal Networks

Main-line metering and DMA stations for district monitoring and non-revenue-water leak detection.

Chemical Processing

Acid/base dosing, reactor feed and cooling circuits, with Hastelloy or tantalum electrodes for aggressive media.

Food & Beverage

Milk intake, juice and CIP wash lines using PTFE/PFA liners and 316L electrodes for hygienic transfer.

Power & Energy

Boiler feed water, condensate return and cooling-tower circuits, PTFE liner rated to +180°C.
