Synchronics Electronics has established deep expertise in EMH metering and control equipment repair since 1994. We service EMH flow meters, pulse interfaces, radio modules, prepaid systems, and allocation devices used across Indian water authorities, HVAC systems, and industrial process control. Our engineers understand EMH calibration protocols, communication interfaces, and field installation requirements — ensuring rapid diagnostics and restoration of critical metering infrastructure that facilities depend on for billing accuracy and process monitoring.
Certified EMH metering equipment repair and calibration for Indian industrial infrastructure.
EMH Product Lines We Repair
Our engineers are trained on the full EMH product range. Below are the major product families we service.
eHZ Energy Meters
EMH's single and three-phase energy meters with MID certification for legal-for-trade billing. Common issues include display failures, no-load errors, communication module faults, and calibration drift requiring laboratory-standard repair procedures.
ULTRAHEAT Flow Measurement
Ultrasonic heating cost allocation and flow measurement devices for district heating and industrial cooling loops. Typical faults: sensor drift, no-display errors, pulse output failures, and communication timeout issues in networked systems.
H Series Pulse Interfaces
EMH pulse counting and output modules for converting analog meter signals to digital protocols (M-Bus, KNX, Modbus). Failures include no pulse output, signal noise sensitivity, and communication buffer overflow in high-frequency environments.
Radio Modules & Remote Reading
Wireless transmission modules (LoRaWAN, GSM, RF) for remote meter data collection in smart metering networks. Common repairs involve antenna damage, frequency calibration loss, encryption key reset, and signal strength degradation.
eHZ Prepaid & Smart Metering
Prepaid energy meter systems with card interface, credit validation, and consumption limit enforcement. Fault patterns: card reader malfunction, EEPROM corruption, load limiter relay failure, and battery backup depletion.
BiCOM Module Communication
EMH's local data interface for meter-to-system communication via optical port, M-Bus, or infrared. Issues include protocol sync failure, baud rate mismatch, optical interface degradation, and timeout errors in polled data collection.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EMH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EMH equipment arriving at our workshop.
- ✓No display or dimmed LCD segments — EMH meters use segmented LCDs powered by low-voltage DC circuits; failure typically results from capacitor aging, backlight inverter circuit failure, or LCD controller loss of synchronisation. Common in eHZ meters installed in harsh outdoor or high-temperature environments.
- ✓Pulse output missing or intermittent — EMH H Series modules and meter pulse outputs rely on opto-coupler isolation or open-collector transistor stages. Failures occur from opto-coupler ageing, photovoltaic degradation under thermal stress, or output transistor leakage — especially in Indian industrial environments with high ambient humidity and temperature cycling.
- ✓M-Bus communication timeout or no response — EMH BiCOM and pulse interface modules use software-based M-Bus stacks sensitive to baud rate errors, signal reflection, and noise on twisted-pair cabling in electrically noisy factory floors. Transceiver chip failures and EEPROM corruption of configuration parameters are common failure modes.
- ✓eHZ prepaid meter: Card reader not recognising cards or load limiter relay stuck — Card reader mechanical wear, contact oxidation, and EEPROM data sector corruption affect card detection logic. Load limiter relay coils burn out under repeated switching cycles or sustained overload conditions common in Indian grid environments with voltage spikes.
- ✓ULTRAHEAT ultrasonic flow sensor: No flow reading or erratic readings — Ultrasonic transducers are sensitive to pipe scale buildup, air bubbles, and temperature sensor drift in Indian water hardness environments. Piezo element degradation and electronics amplifier circuit failure (ceramic capacitor cracking) cause signal loss or noise.
- ✓Radio module: Signal strength degradation or no transmission — EMH LoRaWAN and GSM modules experience antenna connector corrosion, frequency calibration drift, and power amplifier stage failure. Indian installations face metal-rich industrial structures creating RF shielding and path attenuation requiring frequency and transmit power re-tuning.

Frequently Asked Questions — EMH Repairs
Do you repair EMH equipment anywhere in India?+
Yes. Synchronics repairs the full EMH product range — energy meters, flow measurement devices, pulse interfaces, radio modules, and prepaid systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all tier-2/tier-3 cities. Repairs are performed in our Vadodara facility with same-day diagnostics and 5-7 day turnaround for most meters.
Are EMH meters recalibrated and MID-certified after repair?+
Yes. Synchronics re-tests eHZ and ULTRAHEAT meters on calibrated reference standards and returns MID certification documentation. We maintain class 1 accuracy records for legal-for-trade metering and provide energy declaration certificates for utility billing compliance in India.
Can you repair EMH smart metering radio modules (LoRaWAN, GSM)?+
Yes. We specialise in EMH BiCOM radio module repair — including LoRaWAN, GSM, and proprietary RF systems. We recalibrate frequency, reset encryption keys, test signal strength in test chambers, and provide site advice on antenna placement for Indian industrial environments with high RF interference.
What is the typical repair cost for EMH prepaid meter card reader failures?+
Prepaid meter card reader repairs range from Rs. 3,500–8,000 depending on whether the issue is mechanical (contact cleaning) or electronic (EEPROM reprogramming). Load limiter relay replacement costs Rs. 4,000–6,500. Synchronics provides free diagnostics and quotes before starting work.
How long does EMH pulse interface repair take at Synchronics?+
EMH H Series pulse module repair typically takes 3-5 days: 1 day for isolation testing, 2-3 days for component replacement or firmware re-flash, and 1 day for multi-protocol communication verification. Express turnaround (24-48 hours) is available for emergency outages — call our hotline for priority booking.
How do I send my EMH 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 EMH 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 EMH 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 EMH 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.
