The KROHNE DWM 2000 is a highly durable, 3-wire insertion electromagnetic flowmeter engineered specifically to monitor the velocity and flow rate of conductive process liquids, pastes, and heavy industrial slurries. With a variable measurement range scaling from 1 to 8 m/s (3.3 to 26.2 ft/s), this maintenance-free insertion sensor serves as a cost-effective alternative to full-bore inline meters. It accommodates pipe sizes from DN50 up to DN400 (2 to 16 inches) via a standard supplied welding socket, while an extended hardware variant (DWM 2000 L) extends capability to larger line diameters and open channel water networks.
This industrial product briefing provides an engineering teardown of the DWM electromagnetic monitoring platform to streamline your piping layout and instrumentation sourcing:
Before finalizing your piping design or issuing a component specification sheet, cross-check your active process parameters against the verified boundaries of the DWM family below:
| Engineering Parameter | Standard Device Configurations | Operational Notes & Sourcing Limits |

| On-Site Diagnostics | Zero Calibration Push-Button | Instantly clears baseline zero offsets |
The measurement core utilizes an obstructionless electromagnetic design lined with stainless steel (1.4404/316L) and structural ceramics. Because there are no mechanical rotors or gears to foul, the sensor eliminates clogging risks when handling thick slurries or fibrous pastes, significantly lowering operational CapEx compared to mechanical turbine meters.
The converter housing can be rotated or completely removed from the sensor base under live, pressurized process conditions. To guarantee field technician safety during inspection or extraction, long hardware configurations come equipped with an integrated safety chain protection system and can be ordered with a dedicated isolation valve.
Field scaling requires no external software programmers. Technicians can set the full-scale tracking limits directly on the hardware via onboard DIP switches. Additionally, a dedicated zero-calibration button allows engineers to eliminate residual zero-point offsets instantly during initial line packing.
Perfect for monitoring raw mining matrices, paper pulp stock, and highly conductive chemical pastes where inline full-bore sensors would be cost-prohibitive or prone to high erosion rates.
Utilizing the DWM 2000 L extended length model with threaded or sliding connections, water utility engineers can monitor deep gravity-fed aqueducts, wastewater discharge channels, and large-diameter intake mains.
By configuring the instrument with the VARIVENT® N connection system, processing plants achieve complete compliance with FDA and EC 1935/2004 clean-in-place (CIP) regulations for hygienic fluid delivery.
Answer: Yes. While the standard insertion sensor is intended for larger lines via a welding socket, you can bypass welding entirely on smaller lines (DN25…50 / 1…2″) by ordering the optional factory spool piece. This turns the unit into a convenient inline configuration.
Answer: The long sensor version (DWM 2000 L), designed for open channels or pipe sizes wider than 16 inches, is built to adapt to diverse mounting structures. It can be supplied with either a rigid threaded connection or an adjustable sliding connection depending on your depth requirements.
Answer: Unknown. The official technical documentation specifies that this device operates on the electromagnetic principle for monitoring conductive media, but it does not provide the minimum fluid conductivity threshold required to maintain accurate tracking. Please submit your exact liquid composition datasheet to our engineering team for validation.
Answer: If the sensor is installed in a tight pipe gallery or low-clearance skid, you can order the unit with an optional integrated LCD screen directly on the housing, or select from multiple remote display options to mirror the flow rate and velocity data to an accessible control station.
