CONTREC Product Lines We Repair
Our engineers are trained on the full CONTREC product range. Below are the major product families we service.
CONTREC 8+ Flow Computer
Modular flow measurement and data logging platform with multiple input/output channels. Common issues include analogue signal conditioning failures, relay output module faults, and communication protocol stack corruption affecting Modbus TCP and DNP3 connectivity.
CONTREC 400 Series Telemetry Gateway
Industrial SCADA integration and remote terminal unit for pipeline and utility automation. Typical faults involve GSM modem failures, VPN authentication issues, memory card read errors, and corrupted real-time event logging in flash storage.
CONTREC 8 Legacy Flow Computer
Proven older-generation flow measurement platform widely installed in Indian water and oil sectors. Repair challenges include obsolete microprocessor board replacement, analogue-to-digital converter drift, corroded battery-backed RAM, and discontinued sensor calibration modules.
CONTREC Communication Modules
Serial, Ethernet and fieldbus interface cards for CONTREC systems including EIA-232, EIA-485, Ethernet and HART communication modules. Common failures include transformer isolation breakdown, connector pin oxidation, protocol firmware corruption, and transceiver IC short-circuits.
CONTREC Sensor Interface Cards
Signal conditioning modules for turbine, differential pressure, magnetic and ultrasonic flow transmitters. Typical issues involve instrumentation amplifier drift, excitation voltage supply regulation failure, sensor linearisation data loss, and temperature compensation circuit malfunction.
CONTREC Data Logger and Archive Module
Compact data storage and event recording subsystem for offline analysis and regulatory compliance. Faults include SD card controller failure, date-time battery depletion, file system corruption due to unexpected power cycles, and archival software license key loss.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 CONTREC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTREC equipment arriving at our workshop.
- ✓CONTREC 8+ analogue input channel scaling error — Analogue-to-digital converter non-linearity combined with corrupted calibration coefficients stored in EEPROM. Typically occurs after extended thermal cycling or power supply transient stress in Indian industrial environments.
- ✓CONTREC 400 series GSM modem no signal or registration failure — Antenna connector oxidation, SIM card slot contact degradation, or outdated 2G network settings incompatible with Indian telecom carrier upgrades to 4G/5G infrastructure. Firmware version mismatch also common.
- ✓CONTREC flow computer Modbus TCP communication timeout or CRC checksum failure — Ethernet interface transformer winding short-circuit, corrupted TCP/IP stack firmware, or incorrect Modbus slave ID configuration. Physical layer noise common in Indian plants with poor earthing practices.
- ✓CONTREC 8+ relay output module stuck or intermittent contact closure — Mechanical relay armature contamination from industrial dust and moisture, relay coil insulation breakdown, or PCB solder joint cold cracking causing intermittent contact with process equipment sensors.
- ✓CONTREC communication module RS485 bus collision or no slave response — Differential line termination resistor disconnected or incorrect 120 ohm value installed. Noise coupling from adjacent VFD cables or poor cable shielding grounding at field junction boxes common in retrofitted Indian installations.
- ✓CONTREC flow computer display panel unresponsive or corrupted character segments — LCD glass connector pin corrosion, display driver IC solder joints degraded by thermal stress, or internal frame buffer memory corruption from power supply transients and Indian mains supply instability.

Frequently Asked Questions — CONTREC Repairs
Do you repair CONTREC equipment anywhere in India?+
Yes. Synchronics repairs the full CONTREC instrumentation range including flow computers, telemetry gateways, communication modules and sensor interface cards. We offer PAN India express pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all tier-2 industrial cities. All repairs performed in our certified facility in Vadodara, Gujarat with turnaround time of 5-10 working days for standard faults.
What CONTREC flow computer models do you repair and how long does it take?+
Synchronics services CONTREC 8, 8.1, 8.2 legacy platforms and modern CONTREC 8+ and 8+d modular systems. Typical repairs include analogue signal conditioning restoration, Modbus TCP protocol stack fixes, relay module replacement and calibration recertification. Standard turnaround is 7-10 days. Urgent jobs with expedited diagnostics completed within 48-72 hours at priority rates.
My CONTREC 400 telemetry system lost remote connectivity — what do you check?+
Synchronics performs systematic diagnostics starting with GSM modem signal strength testing, SIM card authentication verification, and VPN certificate validation for your Indian telecom network. We review event logs for CONTREC firmware errors, check Ethernet and serial communication interfaces, test battery-backed RTC for time synchronisation, and validate SCADA server address configuration. Once restored, we document the root cause — often outdated 2G-only firmware incompatible with current 4G Indian networks — and implement permanent fixes.
Can you recalibrate CONTREC flow measurement systems to factory specifications?+
Yes. Synchronics recalibrates all CONTREC flow computers and sensor interface modules using industry-standard reference instruments traceable to NIST standards. We retrieve original calibration data from CONTREC servers where available, perform multi-point pressure step testing, regenerate linearisation coefficient tables, and reprogram EEPROM calibration memory. Each repaired unit receives a fresh calibration certificate documenting performance within CONTREC accuracy class specifications.
Do you repair obsolete CONTREC 8 and 8.1 systems no longer supported by the manufacturer?+
Absolutely. Synchronics maintains dedicated legacy repair capability for discontinued CONTREC 8 and 8.1 systems widely deployed across Indian water utilities and refineries. We stock archived firmware images, replacement PCBs, obsolete microprocessor modules and sensor calibration cards. Many Indian plants operate these systems for 20+ years — we specialise in restoring them to operational status when spare parts are unavailable from CONTREC directly.
How do I send my CONTREC 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 CONTREC 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 CONTREC 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 CONTREC 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.
