DANIEL Product Lines We Repair
Our engineers are trained on the full DANIEL product range. Below are the major product families we service.
Orifice Plate & DP Transmitters
Daniel differential pressure transmitters and orifice plate systems for custody transfer and process flow measurement. Common issues include diaphragm seal degradation, impulse line blockages, zero drift, and signal transmission failures in high-pressure applications.
Ultrasonic Flow Meters
Non-invasive Daniel ultrasonic meters for gas and liquid flow measurement with multi-path algorithms. Typical faults involve transducer coupling loss, signal attenuation in dirty pipelines, electronics board corrosion, and calibration drift over time.
Gas Chromatographs & Analyzers
Daniel combustion analyzers and gas composition instruments for process control and emissions monitoring. Repair challenges include detector fouling, thermal instability, carrier gas contamination, and detector response degradation.
Custody Transfer Systems
Integrated Daniel metering skids for oil and gas exchange with simultaneous flow, temperature, and pressure measurement. Faults often stem from sensor array misalignment, corrector electronics failures, data communication dropouts, and environmental stress.
Electronic Devices & Transmitters
Daniel pressure, temperature, and multi-variable transmitters for industrial process loops. Common failures include 4-20mA loop failures, EMI susceptibility, capacitive sensor drift, and connector corrosion in coastal or chemically aggressive environments.
Flow Computer & Modular Systems
Daniel flow correction computers and modular instrumentation for real-time flow calculation and data logging. Typical issues include firmware corruption, memory loss, communication protocol mismatches, and thermal shutdown due to inadequate ventilation.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DANIEL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DANIEL equipment arriving at our workshop.
- ✓Differential pressure transmitter zero drift — Daniel DP transmitters in custody transfer applications experience diaphragm seal degradation and impulse line sludge accumulation, causing creeping zero offset that violates ±0.5% accuracy tolerance required by API standards.
- ✓Ultrasonic transducer signal loss in dirty service — Daniel ultrasonic meters deployed in crude or multiphase pipelines suffer transducer coupling compound degradation and scale buildup, blocking acoustic transmission and causing flowrate calculation errors or meter shutdown.
- ✓Gas chromatograph detector baseline instability — Daniel CG20 and CG30 analyzers experience thermal cycling, detector contamination from carrier gas impurities, and internal electrical noise, resulting in erratic hydrocarbon composition readings and false alarms.
- ✓4-20mA transmitter loop failure — Daniel electronic transmitters fail due to input/output board corrosion, parasitic current leaks from cable grounding issues, or load resistor opens, resulting in floating output signal or complete loop dropout.
- ✓Flow computer firmware corruption and restart loops — Power supply surges, interrupted firmware uploads during field updates, or corrupted nonvolatile memory in Daniel flow computers cause boot failures and loss of historical flow data and calibration settings.
- ✓Custody transfer system data communication dropout — Daniel CMS skids experience intermittent Modbus RTU or Profibus communication failures due to cable EMI exposure, connector pin corrosion at metering junction boxes, or protocol timeout conflicts in multi-sensor arrays.

Frequently Asked Questions — DANIEL Repairs
Do you repair Daniel equipment anywhere in India?+
Yes. Synchronics repairs the complete Daniel instrumentation portfolio — flow meters, differential pressure transmitters, gas analyzers, flow computers, and custody transfer systems. We offer PAN India door-to-door pickup and return from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major industrial cities. All repairs are performed in our certified facility in Vadodara, Gujarat. We maintain API 14.1 and ISO 6976 compliance for custody transfer applications.
Can you repair Daniel custody transfer meters with AGA-8 flow computer corrections?+
Yes. Synchronics specializes in Daniel CMS and integrated metering skids used in oil and gas custody exchange. We repair the entire sensor array (DP transmitter, temperature, pressure, static or dynamic correction computer), recalibrate all parameters per API MPMS Chapter 5 standards, and validate corrected flow output against reference standards before return to pipeline service.
Do you service Daniel ultrasonic flow meters in multiphase environments?+
Absolutely. Daniel Ascent and Series 3098 ultrasonic meters are widely deployed in Indian oil production where crude, water, and gas coexist. We inspect transducers for fouling, clean or replace acoustic windows, recalibrate multi-path algorithms for your specific fluid properties, and return the meter with full performance verification.
What is the turnaround time for Daniel gas chromatograph repair?+
Typical Daniel CG20 and CG30 analyzer repairs take 7-10 working days (detector fouling, thermal block replacement, carrier gas purification, and recalibration). Expedited service (3-5 days) is available for critical refinery applications. We provide loaner instruments upon request to minimize downtime during repair.
Do you offer calibration certificates for Daniel transmitters after repair?+
Yes. All repaired Daniel pressure, temperature, and DP transmitters are calibrated and certified against NIST-traceable standards. We issue ISO 17025 aligned calibration reports with accuracy statements, sensor serial number mapping, and API compliance notes suitable for audit and custody transfer documentation.
How do I send my DANIEL 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 DANIEL 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 DANIEL 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 DANIEL 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.
