BRONKHORST Equipment We Repair — By Category
BRONKHORST Product Lines We Repair
Our engineers are trained on the full BRONKHORST product range. Below are the major product families we service.
Coriolis Mass Flow Controllers (CORI-FLOW)
Real-time mass flow measurement and control using Coriolis effect technology. Common repairs involve flow sensor signal loss, proportional valve hysteresis, and digital controller module failures after thermal cycling or moisture ingress.
Thermal Mass Flow Meters (SIERRA/Bronkhorst THERMAL)
Non-invasive thermal dispersion flow measurement for gases and compressed air in process automation. Failures typically stem from heated sensor wire degradation, signal amplifier drift, or analog-to-digital conversion errors in extreme temperature environments.
Proportional Pressure Regulators (PRESSURE EL-PRESS)
Electronic proportional pressure control valves delivering precise setpoint regulation ±1 percent. Repair scope includes solenoid coil insulation failure, pilot stage spool stiction, and closed-loop feedback amplifier circuit faults.
Vacuum and Low-Pressure Regulators
Specialized regulators for sub-atmospheric and ultra-low-pressure applications in semiconductor and analytical equipment. Common defects include diaphragm material embrittlement, solenoid seal degradation, and pressure transducer non-linearity.
Digital Signal Conditioning Modules (Mini CORI-FLOW, Smart Interface)
Standalone electronics modules providing signal conversion, linearization, and control algorithms for Bronkhorst instruments. Defects involve capacitor dry-out, relay coil burnout, and firmware corruption requiring full electronics replacement or reprogramming.

Common BRONKHORST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRONKHORST equipment arriving at our workshop.
- ✓Mass flow sensor signal loss or erratic readings — Bronkhorst Coriolis and thermal mass flow sensors are sensitive to vibration, humidity, and electromagnetic interference common in Indian industrial environments. Signal conditioning PCB traces corrode or capacitor dry-out reduces amplification gain, causing zero drift or complete signal dropout.
- ✓Proportional valve solenoid coil open circuit — Moisture and ambient humidity in Indian manufacturing environments degrade insulation on Bronkhorst proportional solenoid coils. Thermal cycling in injection molding and autoclave facilities accelerates epoxy resin cracking and copper wire corrosion.
- ✓Diaphragm rupture in pressure regulators — pressure fluctuation or loss of setpoint — Bronkhorst diaphragm material (EPDM, Viton, or FKM) degrades under continuous cycling, thermal extremes, and incompatible process media. Pulse pressures in compressor discharge and gas cylinder applications stress the membrane beyond design limits.
- ✓Analog output 4-20 mA signal not linear or drifting — Digital-to-analog converter circuits and precision resistor dividers on Bronkhorst smart interface modules suffer from thermal drift, solder joint fracture, or precision trimmer potentiometer wear. High-ambient-temperature Indian plants accelerate component aging.
- ✓Relay contact chatter or intermittent control output — Bronkhorst control modules use electromechanical relays for switching proportional valve solenoids. Mechanical vibration from adjacent machinery, combined with high inrush currents, causes contact erosion and arcing. Dust ingress deteriorates contact surfaces.
- ✓Firmware corruption or parameter loss in digital Bronkhorst instruments — Power supply transients, inadequate surge protection, and ESD events in harsh Indian manufacturing environments corrupt EEPROM or flash memory on Bronkhorst smart electronics. Loss of calibration data renders instrument non-functional.

Frequently Asked Questions — BRONKHORST Repairs
Do you repair Bronkhorst equipment anywhere in India?+
Yes. Synchronics is the trusted Bronkhorst repair partner across India. We repair mass flow controllers, thermal mass flow meters, proportional pressure regulators, and all Bronkhorst sensor and electronics modules. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. All repairs are completed at our fully equipped facility in Vadodara, Gujarat.
What is the typical turnaround time for Bronkhorst mass flow controller repair?+
Standard Bronkhorst repair turnaround is 5-7 working days including diagnostics, component replacement, recalibration, and full bench validation testing. Express turnaround of 48-72 hours is available for critical process instruments. We maintain stock of common replacement components — proportional solenoids, diaphragms, and signal conditioning boards — to minimize lead time.
Can Synchronics recalibrate my Bronkhorst mass flow meter to match my current process conditions?+
Yes. Synchronics performs full recalibration and linearization of Bronkhorst thermal and Coriolis mass flow instruments across their rated measurement range. We calibrate using NIST-traceable reference standards and issue certified calibration certificates. We can reprogram range, zero, and span settings to match your specific gas type, pressure, and temperature — no factory hardware changes required.
My Bronkhorst pressure regulator has unstable setpoint — what causes this?+
Pressure instability in Bronkhorst regulators typically results from diaphragm fatigue, pilot stage spool stiction from process fluid contamination, or feedback transducer drift. Synchronics diagnoses the root cause through bench testing, replaces worn seals and diaphragms, cleans the pilot stage, and recalibrates pressure transducers. We verify step response and setpoint stability under simulated process load conditions.
Do you stock original Bronkhorst replacement parts or use aftermarket alternatives?+
Synchronics uses only authentic OEM Bronkhorst parts for all repairs — diaphragms, solenoid coils, proportional valve spools, sensor elements, and electronic modules. We maintain relationships with Bronkhorst distributors and authorized parts suppliers in India to ensure genuine component availability. All repairs include a comprehensive warranty covering parts and labor.
How do I send my BRONKHORST 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 BRONKHORST 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 BRONKHORST 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 BRONKHORST 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.
