FLOWLINE Product Lines We Repair
Our engineers are trained on the full FLOWLINE product range. Below are the major product families we service.
Ultrasonic Level Transmitters
FLOWLINE ultrasonic units measure liquid levels in tanks, vessels, and sumps via sound wave reflection. Common failures include transducer crystallization, foam/agitation false readings, temperature drift, and 4-20 mA output faults. Repairs involve probe cleaning, sensor recalibration, and electronics board troubleshooting.
Capacitive Level Switches and Sensors
FLOWLINE capacitive sensors detect liquid presence in pipes and tanks without moving parts. Typical issues include electrode fouling from coating buildup, false switching due to conductivity changes, and sensing distance drift. Synchronics cleans electrodes, recalibrates switching thresholds, and replaces failed capacitive modules.
Guided Wave Radar Transmitters
Advanced radar-based level measurement for challenging media including foam, agitation, and viscous liquids. Failures stem from cable deterioration, waveguide deposits, microwave circuit faults, and antenna misalignment. Repair involves waveguide inspection, electronics diagnostics, and output linearization.
Point Level Switches
High/low alarm switches for overflow and empty tank protection. Common faults include relay contact corrosion, switch stiction from fluid residue, false alarms due to electrical noise, and cable insulation breakdown in harsh chemical environments.
Display and Relay Modules
FLOWLINE DIN rail-mounted readout units and alarm relay cards that convert transmitter signals to control outputs. Failures include LCD pixel loss, relay contact wear, power supply degradation, and input/output circuit faults. Synchronics replaces relay modules and restores display functionality.

Common FLOWLINE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLOWLINE equipment arriving at our workshop.
- ✓Ultrasonic transmitter 4-20 mA output drift — FLOWLINE ultrasonic probes experience frequency shift and sensitivity loss due to thermal cycling, moisture ingress into the piezo ceramic element, or buildup of mineral scale from contact with tank fluids. Temperature compensation circuitry may also degrade, causing incorrect mA scaling.
- ✓Capacitive sensor continuous false triggering — FLOWLINE capacitive electrodes accumulate conductive coating (from tank vapors, residue, or electrode aging) which reduces sensing distance and causes erratic switching. Low humidity in Indian dry seasons and electrical noise from nearby motors can also saturate the capacitive input.
- ✓Guided wave radar no echo or weak return signal — FLOWLINE GWR waveguides suffer deposits of sticky or crystallized process fluid, antenna feed-point corrosion, or internal cable shorts. Microwave oscillator failure or RF amplifier degradation also causes signal loss. Salt spray environments (coastal Indian plants) accelerate waveguide corrosion.
- ✓Level switch relay contacts stuck or arcing — FLOWLINE point-level switch relays experience contact fusion from inductive load kickback, electrical arcing during high-current switching, or corrosion from atmospheric sulfur and moisture. Over-cycling from turbulence-induced chatter also degrades contacts.
- ✓Display/readout LCD missing segments or completely dark — FLOWLINE USB-200/300 display modules suffer LCD panel degradation from temperature extremes, moisture penetration through connector seals, or backlight LED failure. Contrast adjust pot wear and power supply ripple can also dim or blank the display.
- ✓Ultrasonic beam pattern distortion in foam or turbulence — FLOWLINE ultrasonic sensors rely on clean acoustic transmission; foam, agitation, and vapor blankets scatter the sonic pulse and prevent reliable echo detection. Temperature gradients in large tanks also bend sound waves. Incorrect transducer mounting angle reduces beam clarity.

Frequently Asked Questions — FLOWLINE Repairs
Do you repair FLOWLINE equipment anywhere in India?+
Yes. Synchronics repairs the complete FLOWLINE product range — ultrasonic transmitters, capacitive switches, guided wave radar units, point-level sensors, and display/relay modules. We provide PAN India door-to-door pickup and return shipping from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bengaluru, Ahmedabad, and Surat. All repairs are performed at our Vadodara, Gujarat facility by factory-trained engineers.
How do you handle FLOWLINE ultrasonic transmitters that drift in accuracy over time?+
FLOWLINE ultrasonic probes degrade due to transducer crystallization, thermal cycling, and mineral buildup. Synchronics uses calibrated test stands and reference liquids to recalibrate the sensor's zero and span points, clean the piezo element, and verify the 4-20 mA output before return. We also inspect the temperature compensation circuit and replace capacitors if thermal drift is observed.
What is the typical turnaround time for FLOWLINE repairs?+
Standard diagnostic and repair of FLOWLINE sensors typically takes 5-7 working days including initial testing, cleaning, recalibration, and final verification. For critical equipment, we offer expedited same-day or next-day diagnostics at Vadodara. Rush repairs with priority return can be arranged based on equipment availability and fault severity.
Can Synchronics repair FLOWLINE equipment with ATEX or IEC Ex certification intact?+
Yes. Synchronics maintains protocols for handling certified FLOWLINE equipment and documents all repairs to preserve compliance records. We do not modify certification-critical components (gaskets, potting compounds, pressure ratings) unless necessary. If full recertification is required, we coordinate with FLOWLINE's Indian distributors to arrange official validation.
Do you stock genuine FLOWLINE spare parts and modules?+
Synchronics maintains inventory of common FLOWLINE replacement modules including relay cards, LCD displays, transducers, and cable assemblies. For specialized or obsolete FLOWLINE parts, we source directly from FLOWLINE USA or authorized distributors. We also perform component-level repairs (relay restoration, transducer cleaning, RF module replacement) to minimize parts costs for Indian plant customers.
How do I send my FLOWLINE 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 FLOWLINE 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 FLOWLINE 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 FLOWLINE 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.
