Expert repair of Controlotron electromagnetic flowmeters and process control instrumentation.
CONTROLOTRON Product Lines We Repair
Our engineers are trained on the full CONTROLOTRON product range. Below are the major product families we service.
Controlotron 100 Series Electromagnetic Flowmeters
Precision inline flowmeters for conductive liquids in chemical, pharmaceutical, and water treatment. Common repairs include sensor electrode degradation, zero drift, signal loss, and coil burnout from voltage spikes.
Controlotron 2100 Series Process Controllers
Standalone and panel-mount process controllers with analog input/output and relay switching. Typical faults include input signal conditioning failure, relay contact welding, and firmware corruption affecting setpoint memory.
Controlotron 6000 Series Integrated Control Systems
Networked process control modules combining measurement, computation, and actuation. Common issues include Ethernet communication failure, analog converter malfunction, and power supply degradation under industrial operating conditions.
Controlotron Signal Transmitters and Converters
4-20mA and 0-10V output transmitters for Controlotron sensors. Repairs address current loop failures, impedance mismatch, shielding degradation, and non-linearity in output scaling.
Controlotron Flow Calibration and Validation Systems
Portable and laboratory flow standards used to verify Controlotron meter accuracy. Common maintenance includes sensor recalibration, reference fluid replacement, and temperature compensation module repair.

Common CONTROLOTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROLOTRON equipment arriving at our workshop.
- ✓Controlotron flowmeter zero drift and negative flow errors — Electrode fouling from mineral deposits, biofilm, or corrosion in conductive process liquids. Temperature fluctuations and cable shielding degradation also cause zero offset drift in industrial environments.
- ✓Controlotron 2100 controller losing setpoint and timer values — Lithium backup battery failure or blown capacitors on the memory retention circuit board. Indian heat and humidity accelerate capacitor aging in these legacy controllers.
- ✓Controlotron signal transmitter 4-20mA loop open or unstable — Broken input signal shielding, cold solder joints at connector pins, or current-limiting resistor failure. Industrial vibration and temperature swings degrade solder joints over time.
- ✓Controlotron 6000 series Ethernet communication timeout and data loss — Corrupted firmware in the network interface module, degraded RJ45 connectors from moisture ingress, or EMI coupling from adjacent high-power cables in electrical panels.
- ✓Controlotron electromagnetic coil open circuit or intermittent connection — Thermal cycling and vibration cause wire fracture in the drive coil windings. Moisture and corrosive industrial gases accelerate insulation breakdown in unprotected units.
- ✓Controlotron power supply voltage regulation failure and brownout conditions — Blown voltage regulator IC, failed filter capacitors, or diode bridge rectifier failure. Industrial power quality issues and lightning transients degrade power modules across Indian manufacturing plants.

Frequently Asked Questions — CONTROLOTRON Repairs
Do you repair Controlotron equipment anywhere in India?+
Yes. Synchronics repairs the full Controlotron product range — electromagnetic flowmeters, process controllers, signal transmitters, and integrated control systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other major cities. All repairs are performed at our main facility in Vadodara, Gujarat, with typical turnaround of 5-10 working days depending on fault complexity.
Can you calibrate and validate Controlotron electromagnetic flowmeters?+
Yes. Synchronics performs full calibration of Controlotron flowmeters using NIST-traceable flow standards and precision test rigs. We generate calibration certificates with uncertainty specifications. Recalibration is essential after coil replacement, electrode cleaning, or if zero drift exceeds manufacturing tolerance — common in Indian plants with hard water or saline process fluids.
What is the typical cost and timeline to repair a Controlotron 100 series flowmeter?+
Diagnosis and cleaning typically costs Rs. 3,000-5,000 with 2-3 day turnaround. Electrode replacement or coil rewind runs Rs. 8,000-12,000 with 5-7 days. Full sensor assembly replacement is Rs. 15,000-20,000. Synchronics provides free quotation after initial assessment — send unit or detailed fault description to support@synchronics.co.in.
Are spare parts available for legacy Controlotron 2100 controllers?+
Yes. Synchronics stocks common replacement boards, batteries, and connectors for Controlotron 2100 series. For obsolete integrated circuits, we perform component-level repair and re-manufacture custom circuit card assemblies using reverse-engineered schematics. Many Indian plants rely on these older controllers in critical processes; we keep them running cost-effectively.
How do I know if my Controlotron flowmeter is failing before complete shutdown?+
Watch for: gradual zero offset drift (negative flow readings at standstill), erratic flow jumps despite stable process conditions, loss of communication to PLC/HMI, or decreasing signal amplitude. Preventive maintenance — annual electrode cleaning and full electrical testing — prevents unexpected downtime. Synchronics offers remote advisory services to diagnose issues before failure occurs.
How do I send my CONTROLOTRON 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 CONTROLOTRON 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 CONTROLOTRON 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 CONTROLOTRON 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.
