VE15 Insertion Electromagnetic Flowmeter

• The VE15 Insertion Electromagnetic Flowmeter is designed for large-diameter pipelines - DN200…DN4000 / 8"… 160") carrying electrically conductive liquids.

• Based on Faradayʼs law of electromagnetic induction, the VE15 generates a magnetic field across the measuring section. As conductive liquid flows through this field, an induced voltage proportional to the flow velocity is detected by electrodes in the insertion probe. The converter then calculates the volumetric flow rate from the measured velocity and the known pipe diameter.

• With no moving parts and no internal obstructions, VE15 introduces minimal additional pressure loss, while its microprocessor-based electronics and low-frequency excitation ensure stable and repeatable measurement even under varying operating conditions. It is particularly suitable for water, wastewater, beverages, chemical feed, viscous liquids, pulp and sludge in large pipelines where conventional full-bore meters are difficult or costly to install.

Note: Correct installation (including appropriate insertion depth, alignment and upstream/downstream straight runs) is essential to achieve the specified accuracy on large-diameter pipelines.

• Large-Diameter Raw Water Transmission Main

VE15 is installed on a DN1200 raw water pipeline feeding a municipal treatment plant. The insertion design allows installation with limited civil work compared to a full-bore meter, providing reliable flow data for pumping control, leak detection and energy optimisation.

• Cooling Water Supply in a Steel or Petrochemical Plan

On DN800…DN1600 closed-loop cooling water circuits, VE15 monitors flow distribution to major consumers (furnaces, exchangers, reactors). The wide velocity range: 0.5~8 m/s) and robust stainless-steel construction support continuous operation in demanding industrial environments.

• Wastewater Outfall and Effluent Monitoring

VE15 is used on a large DN1000 wastewater outfall line to provide continuous effluent flow measurement for regulatory reporting and process control. The PTFE-lined probe and explosion-proof options help address chemically aggressive media and classified areas.

• Irrigation Network Master Metering

In a regional irrigation scheme, VE15 units on DN600-DN1400 pipelines provide master metering points for water allocation and loss analysis. The insertion concept enables installation on existing pipelines with minimal interruption to water supply.
