Calibration of flow meters

If you are a measurement technician or process manager, you are aware that calibration of flow meters is important as it enables you to check your meters and optimize them. In this way, the uncertainty between the reading and the true measurement is minimized. At the same time, the basis for correct settlement of water and energy consumption is secured.

Five good reasons to collaborate with Danish Techonological Institute on calibration: 

1. Have your equipment tested and calibrated at an accredited laboratory
Our specialists help you with accredited calibration of your equipment, thus you are guaranteed the highest national level of precision on your equipment.

2. Get your low liquid flow-equipment calibrated and tested
We calibrate your equipment within very low flows, e.g., microflow meters, infusion pumps, insulin, and pain pumps. Furthermore, we provide advice on and test new products within micro flow measurement in our laboratory.

3. Get solutions adapted to your needs
With our high-tech flow test bench and extensive experience in the field, we help to prepare a unique and customer-tailored service that fits your needs exactly. This can only be done in close cooperation with you. Our flow test bench has a high degree of automation and is fully digitized, wich means that our measurements are very safe and consistent. At the flow test stand, we can help your company calibrate, test, and examine flow meters, valves, and other flow equipment for guaranteed traceability at the highest level. Watch the video below and learn more about our advanced flow test stand.

4. Get calibrated and tested equipment for climate adaptation
We also test solutions within climate adaptation. There is no standard in this area yet, which makes it challenging, and it will typically require a solution adapted to the task. Read more about the options in the case below.

5. Have valves tested
We help our customers measuring the valves and we perform pressure loss tests on the valves.

Calibration reduces the uncertainty:

Calibration of flow meters gives you knowledge of your measuring instruments' measuring capabilities and thereby enable reducing the uncertainty from your measurement data in your system. Regular calibration of your flow meter gives you knowledge of the flow meter's stability and shows whether the meter drifts over time.

Accurate measurement of water and energy flow in piping systems is important for billing purposes, in district heating supply systems and in many different industrial processes.

The Flow Laboratory at Danish Technological Institute offers testing and calibration of flow and energy meters as well as fluid related technical measurements for valves, regulators and pumps:

We are able to calibrate dimensions up to 400 mm with a flow capacity up to 1000 m3/h and at water temperatures ranging from 4 °C to 85 °C.

For many years we have offered consultancy services concerning correct flow and energy measurements to producers of measuring equipment, district heating plants and calibration laboratories.

The Flow Laboratory is appointed Danish Metrology Institute for Water Flow (volume, mass and energy flow). And as a national metrology laboratory we participate in intercomparison with other European NMI’s at the highest international level.

The laboratory is accredited by The Danish Accreditation Service (DANAK) – see www.DANAK.dk, Reg. 200 for detailed specifications of the calibration services and uncertainties.

We are accredited in flow calibration and test from to 1 mL/h to 6 l/h - but we also do calibration and tests in the micro flow range 1 µl/h – 6 l/h (accreditation is expected in 2025). You can read about the Microflow Laboratory  here.
