E+H Equipment We Repair — By Category
E+H Product Lines We Repair
Our engineers are trained on the full E+H product range. Below are the major product families we service.
Prowirl Coriolis Flow Meters
E+H Prowirl series measures mass flow with high accuracy across liquid and gas applications. Common faults include sensor drift, transmitter signal loss, temperature compensation errors, and zero-point deviations in high-vibration environments.
Levelflex Level Transmitters
Capacitive and radar level measurement instruments for tank and vessel applications. Typical repair issues include false level readings, diaphragm corrosion, cable gland failures, and transmitter output circuit faults in harsh chemical environments.
Deltabar Differential Pressure Transmitters
Precision differential pressure and absolute pressure measurement for process control and flow compensation. E+H Deltabar units often require recalibration, membrane restoration, reference cell repair, and electronics module replacement.
Smartline Analytical Instruments
pH, conductivity, dissolved oxygen, and turbidity transmitters for water treatment and chemical process monitoring. Common failures include electrode fouling, sensor signal conditioning circuit faults, and firmware calibration loss.
Cerabar Pressure Transmitters
High-accuracy pressure measurement using ceramic capacitive technology for static and dynamic applications. Repairs include diaphragm seal restoration, zero and span calibration, and 4-20mA output circuit reconstruction.
Temposonics Temperature Transmitters
E+H thermowell and transmitter assemblies for temperature measurement in process industries. Typical issues involve RTD or thermocouple element oxidation, transmitter amplifier drift, and connector corrosion in steam or high-moisture environments.

Common E+H Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in E+H equipment arriving at our workshop.
- ✓Prowirl coriolis meter zero-point drift and offset — E+H Prowirl sensors are sensitive to vibration, temperature fluctuation, and extended run periods. Oscillation and mechanical stress cause the vibrating tube to lose its zero calibration, resulting in negative or positive flow bias even with zero actual flow.
- ✓Levelflex capacitive level false high or low reading — E+H Levelflex capacitive sensors suffer from dielectric changes caused by process fluid conductivity variation, electrode coating, or cable capacitance drift. Temperature variation and electromagnetic interference also distort the capacitance measurement in condensate or viscous environments.
- ✓Deltabar differential pressure transmitter no output signal — E+H Deltabar units commonly fail due to membrane rupture, reference cell seal leakage, or capacitive transducer failure. High-pressure spikes, thermal shock, or corrosive process gases cause the silicon membrane to crack, resulting in complete signal loss or erratic 4-20mA output.
- ✓Smartline pH transmitter electrode drift and sensor fouling — E+H Smartline pH sensors experience electrode membrane degradation and salt bridge fouling in high-chloride or protein-rich process streams. Over time, the glass electrode develops cracks or hydration loss, causing measurement drift beyond factory calibration limits.
- ✓Cerabar pressure transmitter 4-20mA signal distortion and nonlinearity — E+H Cerabar ceramic diaphragm sensors degrade under repeated pressure cycling or overpressure events. The capacitive bridge circuit electronics develop component aging, causing output nonlinearity, hysteresis, or intermittent signal dropout across the pressure range.
- ✓Temposonics RTD or thermocouple transmitter input circuit open or intermittent — E+H Temposonics thermowell assemblies suffer connector corrosion, cable insulation breakdown, and RTD/thermocouple element oxidation in steam, humid, or salt-spray environments common in Indian coastal or sugar industry plants. Cold junction compensation circuits also fail due to electrolytic corrosion.

All repairs are processed in our Vadodara facility with 5-7 day turnaround and full technical certification.
What does E+H Prowirl coriolis flow meter repair include?+
E+H Prowirl repair at Synchronics includes disassembly and inspection of the vibrating tube sensor assembly, zero-point calibration using certified gas or liquid standards, transmitter electronics module testing and replacement if needed, thermal compensation verification, and complete mechanical reassembly. We provide ISO 17025 calibration certificates and operate manuals for all repaired units. Typical turnaround is 5-7 days.
Can Synchronics recalibrate E+H Smartline pH or conductivity sensors?+
Yes. Synchronics performs complete recalibration of E+H Smartline pH, conductivity, and dissolved oxygen transmitters. For pH, we use two-point calibration (pH 7.0 and 4.0/10.0 buffers) traceable to Indian Bureau of Indian Standards. For conductivity, we use 0.1413, 1.413, and 12.88 mS/cm standards. All calibrations are documented and valid for Indian plant audits and regulatory compliance.
Why should I choose Synchronics over E+H authorized service for repairs?+
Synchronics offers faster turnaround (5-7 days vs. 2-3 weeks for OEM), lower repair cost (30-50% savings), same-day technical support via email and phone, and on-site guidance for Indian plant engineers. We maintain 99% first-pass repair success and hold full inventory of E+H sensor modules, electronic components, and calibration standards. Since 1994, we have repaired 2000+ E+H units for Indian pharmaceutical, chemical, and food plants.
What is the warranty on E+H instrument repairs from Synchronics?+
All E+H repairs from Synchronics are backed by 12-month parts and labor warranty. If the instrument fails within 12 months due to a defect in our repair work, we will re-repair or replace the unit at no charge. We also provide free technical troubleshooting via phone and email for the first 6 months post-repair, and spare sensor modules are available for critical instruments.
How do I send my E+H 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 E+H 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 E+H 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 E+H 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.
