KROHNE Product Lines We Repair
Our engineers are trained on the full KROHNE product range. Below are the major product families we service.
KROHNE OPTIFLUX Electromagnetic Flowmeters
Full-bore and insertion electromagnetic flowmeters for conductive liquid measurement. Common repairs include electrode erosion, zero drift, signal converter failures, and RS485 communication board faults. Synchronics restores these to OEM specifications.
KROHNE CORI FLOW Coriolis Mass Flowmeters
Coriolis-based mass flow and density measurement for oils, chemicals, and specialty liquids. Repairs address vibration damping issues, oscillator electronics failures, temperature drift compensation problems, and digital output malfunctions.
KROHNE LEVELFLEX Radar Level Transmitters
Non-contact radar and guided-wave level measurement for solids, liquids, and interfaces. Common faults include antenna contamination effects, microwave oscillator degradation, amplifier saturation, and frequency drift in harsh tank environments.
KROHNE ALOGG Level Switches and Sensors
Mechanical and electronic level switches for alarm and shutdown applications. Repairs include float mechanism jamming, reed switch failures, capacitive sensor fouling, and analog output drift compensation.
KROHNE ENVIROMAG Variable Area Flowmeters
Mechanical and magnetic area flowmeters for low-flow and glass-tube applications. Common repairs address float stick-slip, magnet detachment, zero adjustment errors, and glass tube erosion in abrasive slurries.
KROHNE Signal Converters and Transmitters
4-20mA and digital output converters for KROHNE sensors. Repairs cover ADC failure, DAC non-linearity, microprocessor crashes, EMI susceptibility, and HART protocol communication issues.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common KROHNE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KROHNE equipment arriving at our workshop.
- ✓OPTIFLUX electrode surface corrosion and zero drift — Exposure to aggressive chemical environments or galvanic corrosion in stainless steel electrodes. Zero signal offset develops gradually, causing measurement errors of 2-5% on low flows. Common in refineries measuring sour crude or caustic solutions.
- ✓CORI FLOW oscillator electronics frequency instability — Thermal drift of capacitive oscillator circuits or aging of piezo-crystal frequency references. Mass flow readings drift by 0.3-1% over temperature swings, especially problematic in outdoor installations or near furnaces in petrochemical plants.
- ✓LEVELFLEX radar antenna fouling and false level readings — Dust, process condensate, or foam accumulation on antenna surface prevents electromagnetic wave transmission. Level reading locks at maximum or false-low, causing process upsets. Frequent in cement, mineral, and powder handling in Indian plants.
- ✓IFC converter digital communication timeouts and HART protocol failures — Microprocessor watchdog resets, corrupted EEPROM memory, or RS485 transceiver latchup from EMI spikes. HART communication drops intermittently, causing DCS alarms and loss of diagnostic data. Common in plants with poor grounding or nearby VFD installations.
- ✓LEVELFLEX radar transmitter microwave oscillator power degradation — GaAs diode oscillator aging or bias network component drift reduces RF output power from nominal 200mW to <100mW. Signal attenuation causes loss of return echo in applications with high dielectric constants or long probe lengths.
- ✓ALOGG float mechanism jamming and level switch hysteresis errors — Solid particulate entrapment in float pivot bearing, viscous liquid coating float surface, or magnet adhesion to ferrous contamination. Switch actuation point drifts or becomes unrepeatable, violating alarm setpoint accuracy ±2mm specifications.

Frequently Asked Questions — KROHNE Repairs
Do you repair KROHNE equipment anywhere in India?+
Yes. Synchronics repairs the full KROHNE product range across all 15 product lines — flowmeters, level transmitters, pressure sensors, and signal converters. We offer PAN-India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and 100+ other cities. All repairs are handled at our Vadodara facility in Gujarat with ISO 9001 quality control.
Can you re-calibrate and certify KROHNE flowmeters after repair?+
Yes, absolutely. Synchronics provides ISO 17025 accredited calibration for OPTIFLUX, CORI FLOW, and all other KROHNE measurement instruments. We use reference standards traceable to NIST and issue calibration certificates valid for regulatory compliance in refineries, pharmaceuticals, and food plants across India. Turnaround is 5-7 days.
What is the typical repair cost for a KROHNE CORI FLOW mass flowmeter?+
CORI FLOW repairs typically cost INR 18,000-35,000 depending on the fault. Oscillator module replacement is INR 22,000-28,000. Coriolis tube replacement (if fractured) is INR 35,000-50,000. Synchronics provides free diagnostics and a quote before any work begins. Most repairs are completed in 5 days and are significantly cheaper than factory replacement.
How do KROHNE radar level transmitters perform in Indian cement and mineral plants?+
KROHNE LEVELFLEX radar is excellent for cement and mineral slurries, but antenna fouling is the most common issue in India's dusty kiln and grinding environments. Synchronics provides preventive maintenance service including antenna inspection, gasket replacement, and firmware updates every 6 months. This prevents unplanned shutdowns and keeps accuracy within ±2% across full range.
Do you stock KROHNE spare parts for quick repairs?+
Synchronics maintains inventory of high-demand KROHNE components including oscillator modules, signal converter PCBs, RS485 transceivers, and electrode assemblies. For special items, we have expedited import channels from KROHNE Germany with 7-10 day lead times. This ensures fast repairs without long factory waiting periods common in Indian industrial repair.
How do I send my KROHNE unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a KROHNE drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on KROHNE repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your KROHNE unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
