Installation and Commissioning of MIM and MIK Flow Meters

Proper installation of KOBOLD / KOBOLD Messring GmbH MIM and MIK series electromagnetic flow meters guarantees high measurement precision for conductive process streams.

Prior to mounting the flow sensor into piping, engineers must ensure straight calming pipe runs of at least five nominal pipe diameters upstream and three diameters downstream from the sensor.

The flow tube must remain completely filled with liquid during all pumping operations; vertical upward flow orientations are strongly recommended.

Establishing dependable grounding connections between the sensor body, ground electrodes, and adjacent pipework prevents stray electrical potentials originating from variable frequency drives from distorting analog 4-20 mA transmission signals.

Selection and Maintenance of KSK Variable Area Flow Meters

KOBOLD KSK and KSM variable area flow meters deliver direct visual flow monitoring for water, saline solutions, and aggressive chemical reagents.

When selecting a flow meter, operating pressure, system temperature, and fluid density must be evaluated because metering floats are calibrated for specific fluid densities.

Routine maintenance involves examining the internal conical polysulfone flow tube for mineral deposits or suspended solid buildup.

Cleaning the metering tube requires gentle flushing with neutral detergent solutions without abrasive brushes, safeguarding internal flow tube contours and maintaining precise scale calibration alignment across long operational runs.

Calibration and Operation of TMU Coriolis Mass Flow Meters

KOBOLD TMU series Coriolis mass flow meters provide multi-parameter measurement of liquid and gas mass flow without sensitivity to fluid viscosity or velocity flow profiles.

To eliminate external structural strain on oscillating measuring pipes, the flow meter must be supported on rigid framework without piping overhang on connecting flanges.

During plant commissioning, operators execute zero-point calibration routines under completely filled, zero-flow conditions at operating temperature.

Ongoing monitoring via Modbus or HART digital interfaces tracks dual-tube resonance frequencies, enabling early detection of sticky fluid coatings or erosive thinning of internal sensor tubes.

Protecting PAD and PMP Pressure Transmitters with Diaphragm Seals

Deploying KOBOLD PAD, PAS, and PMP pressure transmitters on pulsating lines or severe process media requires DRM diaphragm seals. The flexible diaphragm barrier isolates sensitive piezoresistive sensor elements from direct exposure to crystallizing, hot, or viscous chemicals.

The internal fill chamber contains vacuum-degassed silicone oil transmitting line pressure smoothly without thermal lag.

To mitigate hydraulic shocks originating from rapid-closing shutoff valves, an impulse siphon loop or an adjustable needle snubber is installed upstream, protecting the silicon sensing chip from irreversible strain and overload.

Inspection Protocol for NBK Bypass Level Indicators

KOBOLD NBK series magnetic bypass level indicators mount directly to tanks and distillation vessels utilizing communicating vessel physics for liquid level indication.

Routine servicing requires checking free axial movement of the cylindrical float within the non-magnetic titanium or stainless steel bypass tube.

Periodically flushing the bypass column through the lower drain port removes accumulated sludge, preventing buildup from arresting internal permanent magnets.

When adjusting external NBK-R reed contacts or 4-20 mA transmitters, technicians verify crisp flipping response of two-color indicator rollers as the float traverses vessel height.

Configuring TDD Electronic Temperature Switches and Thermowells

KOBOLD TDD digital temperature switches and TDA sensors safeguard hydraulic power units, gear drives, and bearing blocks against critical thermal overheating.

Mounting the Pt100 platinum RTD element inside a solid-machined stainless thermowell seals the pressurized pipework, allowing probe servicing without shutting down line pressure.

Using the digital programming buttons, operators configure independent setpoints for early thermal warning and emergency equipment shutdown. Setting switching hysteresis prevents rapid relay chatter when temperatures hover near trip thresholds, prolonging electrical contact service life.
