Wide Calibration Range & Capabilities
Our facility is equipped to calibrate a wide variety of flowmeters used across multiple industries, ensuring comprehensive support for all types of flow measurement needs. This includes:
-
Electromagnetic Flowmeters – Ideal for water, wastewater, and industrial liquid flow measurement with high accuracy and zero moving parts.
-
Ultrasonic Flowmeters – Suitable for both clean and dirty fluids, offering non-intrusive and clamp-on measurement capabilities.
-
Turbine Flowmeters – Commonly used for clean, low-viscosity liquids where precision and repeatability are essential.
-
Positive Displacement (PD) Meters – Preferred for highly accurate measurement of viscous liquids, oils, and chemicals.
-
Venturi & Differential Pressure Flowmeters – Used in large pipelines, process plants, and utility networks for reliable measurement based on pressure drop principles.
Our calibration systems are engineered for exceptional accuracy and stability, enabling precise calibration even for large-diameter industrial meters operating under high flow conditions. With our controlled testing environment, advanced reference standards, and automated data capture systems, we deliver consistent, repeatable, and traceable results for every meter.
Automatic Calibration Software
We use advanced automatic calibration software that precisely adjusts and corrects the K-factor of flowmeters, ensuring every device delivers accurate, stable, and repeatable performance. This intelligent software enhances calibration efficiency and guarantees that each meter meets the required accuracy standards for its intended application.
The software provides:
-
Automated test sequences that eliminate human error and maintain consistency across multiple calibration cycles.
-
Error-free calibration processes with built-in validation checks to ensure the correctness of flow readings.
-
Real-time data logging and reporting, enabling operators to review performance trends, detect deviations, and maintain complete calibration histories.
-
High repeatability and traceability, supported by NABL-referenced standards for reliable and audit-ready results.
-
Digital generation of calibration certificates, ensuring fast, transparent, and tamper-proof documentation.
By reducing manual intervention, the system significantly improves operational reliability, speeds up calibration turnaround time, enhances data integrity, and ensures compliance with regulatory and industry standards. It also supports large-scale batch processing, making it ideal for utilities, municipalities, and industrial clients handling high volumes of flowmeters.
Traceability & Certification
Every calibration process in our facility is carried out under strict quality protocols, ensuring full traceability to NABL-accredited reference standards. This guarantees that all measurements are accurate, repeatable, and fully compliant with industry norms and regulatory frameworks. Each flowmeter undergoes controlled testing using certified reference equipment, and all procedures follow documented calibration methods to maintain consistency and reliability.
Our calibration certificates include:
-
Meter details – model, serial number, application, and technical specifications
-
Calibration method – detailed procedure followed and testing parameters used
-
Flowrate points – multiple flow values tested to ensure accuracy across the meter’s operating range
-
Uncertainty calculations – complete measurement uncertainty analysis in line with NABL and ISO guidelines
-
Traceability references – details of reference standards and their certification validity
These comprehensive documents ensure complete transparency, support regulatory inspections, and meet the requirements of utilities, industries, and audit authorities. Our standardized approach enhances confidence in flow measurements, reduces operational discrepancies, and helps clients maintain long-term compliance and system integrity.
High Accuracy & Performance Assurance
By using precision instruments, certified reference standards, and advanced automated validation tools, our calibration lab enables industries to achieve highly accurate and reliable flow measurement. This accuracy reduces energy losses caused by incorrect flow readings, enhances operational efficiency, and ensures fair and transparent billing for utilities and industrial customers. Automated validation improves consistency, minimizes human error, and supports continuous monitoring of equipment performance. In addition, precise calibration helps organizations meet regulatory requirements, pass audits with confidence, and maintain long-term compliance with national and international standards.
