In many modern skid systems, the actual installation problem is no longer pipe routing. The larger issue is transmitter clearance.
Inside compact chemical dosing cabinets, OEM process modules, or containerized water treatment systems, engineers often struggle with:
This becomes especially noticeable when multiple flowmeters are mounted side-by-side inside narrow stainless-steel enclosures.
The Endress+Hauser Proline Promag E 100 was designed specifically for these high-density installations. Compared with conventional magmeters using large remote transmitters or oversized housings, the Promag E 100 uses a compact integrated transmitter structure that simplifies installation in confined process areas.
Instead of treating compactness as a secondary feature, the E 100 is built around space efficiency from the beginning.
On large process plants, transmitter size is rarely a major concern. But on smaller modular systems, physical spacing quickly becomes a limiting factor.
Typical examples include:
In these projects, technicians often discover that standard electromagnetic flowmeters leave almost no room for:
The compact housing of the Promag E 100 helps reduce these issues during both assembly and maintenance.
Many skid builders also use it when several instruments must be mounted within a short pipe section together with pressure transmitters, dosing pumps, and conductivity sensors.
Chemical resistance is another major concern in dosing applications.
The Promag E 100 uses a PTFE liner suitable for conductive chemical liquids commonly found in industrial treatment systems.
Typical media include:
Unlike rubber-lined meters that may gradually age in aggressive chemical environments, PTFE provides strong resistance against chemical permeation and liner degradation.
The meter is available from DN15 to DN600, allowing the same platform to be used across both small dosing lines and larger transfer systems.
The E 100 is commonly selected for:
For larger municipal water distribution systems, some facilities combine compact inline meters with utility-focused systems such as the KROHNE WATERFLUX 3300 on main supply pipelines.
One issue frequently encountered during startup is software access.
Many traditional field instruments still require:
This becomes inconvenient when technicians are working on temporary commissioning laptops onsite.
The Promag E 100 includes an integrated web server that allows direct browser-based access to the device.
In practice, this means technicians can:
using a standard laptop or tablet browser.
This approach is especially useful on remote skid installations where dedicated configuration tools are not always available.
In many industrial plants, calibration verification normally requires partial process interruption or removal of the instrument.
The Promag E 100 reduces this maintenance burden using Heartbeat Technology.
The system continuously checks:
without interrupting the active process line.
This helps maintenance teams generate verification records while keeping the process operational.
For facilities operating under ISO quality systems, this can simplify audit preparation and reduce unnecessary downtime.
The Promag E 100 supports multiple industrial communication protocols including:
This allows easier integration into both conventional PLC systems and newer Ethernet-based process networks.
For skid manufacturers, selecting the correct communication option early in the project can reduce gateway hardware and simplify panel wiring later.
One common issue with electromagnetic flowmeters occurs on non-conductive piping systems.
When installed on:
the process fluid may not establish stable grounding automatically.
In these situations, grounding rings or grounding electrodes are usually recommended to stabilize the measurement signal.
Unstable grounding is one of the most common causes of fluctuating readings during commissioning.
Vertical upward flow installation is generally preferred because it helps keep the measuring tube completely full.
When horizontal installation is unavoidable:
Air pockets inside the measuring tube can affect signal stability.
PTFE liners should not be excessively compressed during installation.
Over-tightening flange bolts may gradually deform the liner into the flow path, especially on smaller pipe sizes.
Using a calibrated torque wrench and cross-pattern tightening sequence helps avoid unnecessary liner stress.

For applications requiring SIL-rated protection or handling highly abrasive slurry media, some engineers instead specify the KROHNE OPTIFLUX 4400 on critical process lines.
Yes, but proper grounding is important. Grounding rings or reference electrodes may be required to stabilize the signal.
Yes. The PTFE liner is commonly used for conductive corrosive chemicals including sodium hypochlorite and caustic solutions.
No. Heartbeat Technology performs internal verification while the process remains active.
It is generally better to maintain stable flow conditions and avoid excessive pulsation directly at the sensor inlet.
Typical industries include water treatment, chemical dosing, industrial utilities, OEM skid manufacturing, and wastewater processing.
