Advice on gas measurement
Receive a quote tailored to your needs
The measurement tools used for gas measurement are available in a variety of models and price classes. Kiwa advises suppliers and producers of measuring instruments on the chosen measuring concepts, the materials used and test procedures. In addition, Kiwa advises the users of these measuring instruments on management and maintenance practices and the way in which these measuring instruments should be checked and calibrated.
Kiwa also participates in various standards committees both nationally and internationally. As a result, Kiwa has extensive knowledge of the regulations and relevant standards and is capable of providing advice for specific gas measuring problems that is completely in line with those regulations and standards, and also with recent (technological) developments.
Measurement differences may arise when billing gas flows (differences between the purchased and sold gas volumes). Kiwa investigates cases like this in order to identify whether the measurement difference is caused by measuring errors, inaccuracies in the measuring instruments in use or by administrative errors. The results of this investigation can be used as a basis for corrective action.
Target group
Gas suppliers, gas network operators, gas measurement specialists, gas meter manufacturers, gas purchasers, central and local government
Verification technical aspects
Based on the Dutch Gas Transportation and Delivery Act (Gaswet), a regional gas network operator (regionale gasnetbeheerder or RNB) is responsible for gas quality. In this context, quality means the composition of the gas and its odour characteristics.

Gas imaging camera: Quick and efficient detection of leaks in bio methane or biogas installations
Leaks in bio methane or biogas installations can’t only lead to dangerous situations but also pose a threat to the environment. Additionally, leaking gas represents a direct financial loss. That’s why it is crucial to detect and repair leaks and vulnerable areas in green gas and biogas systems as quickly as possible. Kiwa can assist with this by conducting camera inspections using an advanced gas imaging camera.
