Certified Flow Research thermal mass and ultrasonic flow meter repair with on-site diagnostics and recalibration.
FLOW RESEARCH Product Lines We Repair
Our engineers are trained on the full FLOW RESEARCH product range. Below are the major product families we service.
Thermal Mass Flow Meters
Flow Research's signature thermal mass flow measurement technology for gases and vapours. Common issues include sensor drift, excessive zero offset, non-linear output curves, and failure to track dynamic flow changes. These instruments require precision recalibration and sensor element inspection.
Ultrasonic Flow Sensors
Non-invasive clamp-on and in-line ultrasonic flow transducers for liquid and gas measurement. Repair challenges include transducer bonding degradation, acoustic coupling loss, signal conditioning circuit failures, and digital output instability.
Signal Conditioners and Transmitters
Modular signal conditioning units that process raw flow sensor signals into standardised output (4-20mA, 0-10V, digital). Faults include amplifier drift, reference voltage instability, A/D converter errors, and communication module failures.
Process Control Modules
Integrated PLC-based flow totalizers and process controllers for automated dosing, batch control, and inventory management. Common defects involve program memory corruption, real-time clock failure, relay contact degradation, and Ethernet/serial port communication breakdowns.
Field Mounted Transmitters
Robust 2-wire and 4-wire transmitters for direct installation on process pipes and vessels. Issues include sensor element burnout, transmitter housing corrosion, connector pin oxidation, and loss of HART communication.

Common FLOW RESEARCH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLOW RESEARCH equipment arriving at our workshop.
- ✓Thermal mass flow meter reading drift or zero offset — Sensor contamination, thermal calibration drift, or failure of the temperature compensation circuit within the flow meter electronics. Flow Research thermal sensors are highly sensitive to minute deposits and temperature gradients, causing systematic measurement errors over time.
- ✓Ultrasonic transducer loss of acoustic coupling signal — Degradation of the acoustic bonding interface on clamp-on sensors, corrosion of transducer piezo elements, or misalignment of dual-frequency transducer pairs. Flow Research ultrasonic sensors require perfect acoustic coupling to generate consistent cross-correlation signals.
- ✓Signal conditioner 4-20mA output non-linear or stuck at fixed value — Failure of output operational amplifier stage, D/A converter malfunction, or corruption of firmware linearisation tables within the conditioner microcontroller. Flow Research conditioners use precision current-loop architectures sensitive to component aging.
- ✓HART communication loss or ModBus timeout from Flow Research transmitter — Degradation of 2-wire HART interface circuitry, RS-485 termination resistor failure, or embedded modulation circuit malfunction. Industrial environments subject to electrical noise can corrupt the HART modem or destabilise digital communication layers.
- ✓Flow totalizer accumulator error or batch controller runaway dosing — Program memory bit flip or EEPROM corruption in Flow Research FCM series controllers, loss of real-time clock synchronisation, or stuck relay contacts preventing solenoid valve closure. Extended runtime and thermal cycling degrade memory retention.
- ✓Sensor element short circuit or open circuit resistance reading — Internal sensor resistance (RTD or thermistor) failure due to thermal shock, vibration-induced wire fatigue, or moisture ingress into sealed sensor bulbs. Flow Research's precision platinum RTD elements are susceptible to bridging when contaminated.

Frequently Asked Questions — FLOW RESEARCH Repairs
Do you repair Flow Research equipment anywhere in India?+
Yes. Synchronics repairs the full Flow Research product range - thermal mass flow meters, ultrasonic sensors, signal conditioners, transmitters, and process controllers. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other metros. All repairs are performed at our ISO 9001 certified facility in Vadodara, Gujarat with 2-3 week turnaround.
Can you recalibrate Flow Research thermal mass flow meters to factory specification?+
Absolutely. Synchronics is equipped with precision gas flow standards traceable to NIST for recalibrating Flow Research RFT series meters. We execute full thermal mass characterisation, zero/span adjustment, and temperature compensation calibration. Calibration reports with uncertainty budgets are provided per Flow Research documentation requirements.
What happens if my Flow Research ultrasonic transducer coupling fails mid-process?+
Synchronics offers emergency same-day shipping for spare transducers to keep your process running. We maintain inventory of Flow Research ultrasonic clamp-on and in-line transducers. Simultaneously, we repair your failed transducer with bonding renewal and full acoustic characterisation, typically completed within 5 business days.
Do Flow Research signal conditioner modules need firmware updates?+
Flow Research periodically releases firmware patches for the IFC and TransConnect series to improve linearisation accuracy, add communication protocol support, or fix HART modem bugs. Synchronics maintains the latest firmware libraries and can reprogram your conditioner if updates are available. We also provide custom linearisation programming for multi-range or non-standard sensor applications common in Indian processing plants.
How do I know if my Flow Research flow meter needs recalibration or replacement?+
Common indicators are measurement drift exceeding +/- 2%, unexplained zero offset shifts, non-linear response to known flow changes, or communication timeouts. Synchronics offers free diagnostic evaluation - we'll test your meter, compare readings against a certified reference standard, and advise whether repair or spare meter exchange is most cost-effective. Many Indian petrochemical and pharma plants choose our preventive recalibration service every 18-24 months.
How do I send my FLOW RESEARCH 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 FLOW RESEARCH 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 FLOW RESEARCH 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 FLOW RESEARCH 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.
