If it measures water flow, we can calibrate it.

      The HT R&D laboratory having Hydro Turbine/Pump Model Testing test bed and Water Flow calibration Facility, established in 2018, has been providing technical consultancy, research, training, testing and calibration in flow measurement for our clients across the globe. Activities of Water Flow calibration Facility are centered around calibration and testing of flow products including flow meters, valves with water as medium of flow.

Prominent Features

• Gravimetric Calibration method as per ISO 4185:1980
• Comparison Calibration method using reference flow meters
• Accredited as per ISO/IEC 17025:2017 accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL)
• Full compliance and audit readiness for your flow meter with complete and traceable calibration
• Secure accurate and repeatable results for your devices over their entire life cycle by putting our expertise
• The software is written in LabVIEW written by HT R&D lab as this has proved to be the most effective platform for calibration excellence and gives freedom to develop and introduce improvements at any time along with Software validation
• Temperature control during calibration by provision of chiller plant during calibration
• Ensuring constant flow-rate by use of transfer pumps to maintain inlet water level during calibration
