GMS Product Lines We Repair
Our engineers are trained on the full GMS product range. Below are the major product families we service.
GMS Flow Measurement Systems
Electromagnetic, turbine, and ultrasonic flow meters for liquid and gas applications. Common repairs include signal conditioning card failures, coil burnout, and electromagnetic interference issues in high-voltage industrial environments affecting meter accuracy.
GMS Pressure and Level Transmitters
4-20mA and digital output pressure/level sensors for process vessels and pipelines. Typical faults include diaphragm seal degradation, zero/span drift, 4-20mA signal loss, and connector corrosion in humid refinery and pharmaceutical environments.
GMS Temperature and Limit Controllers
Analog and digital temperature control modules with analog I/O and alarm output cards. Common failures: relay contact welding, thermal sensor circuit degradation, display panel corrosion, and PID algorithm drift in high-temperature furnace and kiln applications.
GMS Process Automation Interface Cards
Modular I/O cards, analog multiplexers, and signal conditioners for distributed control networks. Repair scope includes failed op-amp circuits, corroded edge connectors, faulty opto-isolators, and analog-to-digital conversion errors in harsh factory floors.
GMS Valve Positioners and Actuator Controllers
Pneumatic and electric valve control electronics with integral feedback. Issues involve spool valve failures, pressure regulator drift, solenoid coil degradation, and feedback potentiometer wear in steam, cryogenic, and corrosive gas applications.

Common GMS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GMS equipment arriving at our workshop.
- ✓Flow meter zero offset and signal drift — GMS electromagnetic and ultrasonic meters experience calibration drift due to coil contamination, pipe scale buildup, or analog conditioner card aging. Temperature compensation circuits in transmitter modules fail, causing erratic 4-20mA output variance of 2-5%.
- ✓4-20mA transmitter signal loss or stuck value — GMS pressure and level transmitters fail due to corroded D-sub connectors common in coastal and chemical plant humidity, broken 4-20mA loop driver circuits on PCB, or blown precision op-amp stages handling sensor amplification in high-EMI zones.
- ✓Temperature controller display blank or erratic readings — GMS temperature control modules develop LCD/LED display connector fractures from thermal cycling in furnace rooms, degraded thermal sensor input circuits, or failed power supply regulation delivering unstable bias to display drivers and sensor preamplifiers.
- ✓Relay contact welding and stuck alarm outputs — GMS limit controller relays weld under arc conditions when switching inductive loads (motor starters, solenoid valves) without adequate snubbing, common in rapid on-off cycle pneumatic valve control and high-power alarm circuits exceeding relay contact rating.
- ✓Valve positioner feedback potentiometer wear and hysteresis — GMS pneumatic valve positioner potentiometers wear from continuous proportional modulation in throttling service (steam regulators, cryogenic isolation valves). Contacts develop intermittent connection, creating control oscillation and feedback linearity errors of 3-8% across valve stroke.
- ✓Analog multiplexer channel crosstalk and false readings — GMS MUX series multiplexers develop inter-channel leakage in high-density I/O modules due to PCB moisture absorption, failed opto-isolator chips isolating analog channels, or degraded analog switch (CMOS) reliability in multi-year field service without maintenance.

Frequently Asked Questions — GMS Repairs
Do you repair GMS equipment anywhere in India?+
Yes. Synchronics repairs the complete GMS product portfolio including flow meters, pressure transmitters, level sensors, temperature controllers, and valve positioners. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Jaipur, Ahmedabad, Kolkata and all other cities. All repairs completed at our 5000 sqft ISO 9001:2015 facility in Vadodara, Gujarat with 2-4 week turnaround for most GMS electronics.
What is your experience with GMS flow meter electronics repair?+
Synchronics has repaired GMS MKF electromagnetic meters, GMS-TFM turbine flow systems, and MKU ultrasonic series since 2010 across Indian refineries, petrochemical plants, and pharma manufacturers. We handle analog conditioner card failures, coil demagnetization, and 4-20mA loop driver repairs. Our technicians recalibrate flow electronics using NIST-traceable standards and pressure/temperature compensation adjustment to restore meter accuracy within +/- 0.5% for critical custody transfer applications.
Can you repair GMS valve positioner feedback circuits?+
Yes. We repair GMS-VP-2000 positioner feedback loops, proportional valve solenoid drivers, and pressure compensator circuits. Common repairs include potentiometer replacement, spool valve cleaning, and electronic feedback amplifier recalibration. We test positioner linearity across full valve stroke (0-100%) and verify pneumatic supply stability to ensure smooth proportional control in critical throttling applications like steam regulation and cryogenic isolation.
What GMS spare components do you stock?+
Synchronics maintains inventory of GMS connector assemblies (D-sub, M12), common op-amp ICs (precision instrumentation amplifiers), relay modules, solenoid driver transistors, CMOS analog switches, and opto-isolators. We also stock GMS pressure diaphragm seals, thermal sensor elements, and display LCD modules. For obsolete or unavailable components, our engineers perform functional equivalent substitution with full technical documentation and re-qualification testing.
Do you offer calibration certificates for repaired GMS equipment?+
Yes. Synchronics issues traceable calibration certificates for all repaired GMS sensors, transmitters, and controllers. Our calibration lab holds NABL accreditation for pressure, temperature, and electrical parameter measurement. We verify GMS electronics against reference standards, document zero/span offsets, and provide temperature compensation certificates suitable for pharmaceutical cGMP documentation, refinery SCADA compliance, and ISO audits across Indian manufacturing industries.
How do I send my GMS 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 GMS 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 GMS 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 GMS 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.
