DYNASONICS Product Lines We Repair
Our engineers are trained on the full DYNASONICS product range. Below are the major product families we service.
Dynasonics Ultrasonic Flow Meters
Transit-time and Doppler ultrasonic flow measurement instruments for custody transfer, process monitoring, and billing applications. Common issues include transducer degradation, coupling loss, signal attenuation in turbulent flow, and temperature compensation errors.
Dynasonics Level and Density Sensors
Non-contact ultrasonic level transmitters and density analyzers for tanks and vessels. Repair challenges include sensor fouling, acoustic impedance mismatches, false echo suppression failures, and 4-20mA output circuit faults.
Dynasonics Signal Processors and Controllers
Intelligent signal conditioning and flow control modules that integrate with Dynasonics sensors. Common defects involve signal amplifier degradation, ADC conversion errors, relay board failures, and communication protocol issues.
Dynasonics Transducer Assemblies
Piezoelectric transducers and coupling systems critical for ultrasonic signal transmission and reception. Typical failures include piezo element cracking, backing material delamination, crystal frequency drift, and acoustic matching layer erosion.
Dynasonics Analytical and Process Instrumentation
Integrated ultrasonic analyzers for multi-parameter monitoring in refineries and chemical plants. Issues include software crashes, sensor fusion errors, data logging memory corruption, and network communication timeouts.

Common DYNASONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNASONICS equipment arriving at our workshop.
- ✓Ultrasonic transducer piezo element failure — Piezoelectric ceramic elements in Dynasonics transducers degrade due to thermal cycling, overvoltage transients, or mechanical vibration. Cracked or delaminated piezo elements prevent acoustic energy transmission, resulting in zero or extremely weak signal output.
- ✓Signal processor amplifier saturation and clipping — High-turbulence flow conditions or proximity to external vibration sources saturate the input amplifier stage in Dynasonics signal processors, causing waveform clipping and erratic flow rate calculations or false density readings.
- ✓Acoustic coupling loss and transducer decoupling — Thermal cycling, mechanical shock, or corrosion of mounting interfaces cause Dynasonics transducers to partially decouple from process piping or tank walls, reducing acoustic contact and signal strength below detection thresholds.
- ✓4-20mA output signal drift and non-linearity — Aging operational amplifiers, loose potentiometer settings, or capacitor drift in the signal conditioning circuit of Dynasonics controllers causes output current to drift outside calibrated range or exhibit non-linear response across the flow measurement span.
- ✓Frequency shift and crystal aging in transducers — Piezo transducers in Dynasonics instruments drift from nominal center frequency (typically 1-2 MHz) due to electrical stress, temperature exposure, or material fatigue, reducing signal-to-noise ratio and measurement resolution.
- ✓Temperature compensation circuit failure — Thermocouple drift, RTD calibration loss, or temperature-dependent amplifier bias failures in Dynasonics flow meters prevent proper sonic velocity temperature compensation, leading to large measurement errors across seasonal temperature swings.

Frequently Asked Questions — DYNASONICS Repairs
Do you repair Dynasonics equipment throughout India?+
Yes. Synchronics offers pan-India repair service for all Dynasonics ultrasonic flow meters, level sensors, and signal processors. We provide free pickup from major industrial hubs including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Kolkata, and Ahmedabad. All repairs are performed in our ISO-certified Vadodara facility and tested to original Dynasonics performance standards.
What is your turnaround time for Dynasonics transducer and signal processor repairs?+
Typical turnaround is 5-7 working days for transducer replacement and recalibration, and 7-10 days for signal processor diagnostics and component-level repair. Critical custody transfer applications are prioritized. Express diagnostics available within 24 hours for emergency downtime situations affecting refinery and petrochemical operations.
How do you handle Dynasonics ultrasonic transducer calibration and frequency verification?+
Synchronics uses calibrated ultrasonic bench test systems to verify transducer frequency, impedance, and acoustic output. We validate transducer performance against NIST-traceable ultrasonic standards and provide calibration certificates for compliance with petroleum custody transfer and pharmaceutical quality standards. Frequency compensation tables are updated in Dynasonics controllers post-repair.
Can you repair Dynasonics signal processors with firmware or software corruption?+
Yes. Synchronics performs firmware diagnostics, EEPROM rewriting, and flash memory recovery for Dynasonics signal processors and data loggers. We maintain legitimate firmware libraries and update software with genuine Dynasonics releases. Custom configuration reloading is provided for multi-sensor systems integrated into refinery and chemical plant networks.
Do you stock genuine Dynasonics spare parts and transducer assemblies?+
Synchronics maintains an inventory of high-demand Dynasonics piezo transducer assemblies, coupling kits, signal processor cards, and amplifier modules. For model-specific components, we source directly from authorized distributors and provide genuine parts with authenticity certification. Warranty on replaced components is 12 months for transducers and 18 months for electronics.
How do I send my DYNASONICS 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 DYNASONICS 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 DYNASONICS 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 DYNASONICS 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.
