SICK is a reliable and experienced manufacturer of ultrasonic gas meters. In addition, SICK sets high standards with the long term durability, accuracy and stability of its products. In order to test the long-term stability of an ultrasonic gas meter, it has to be recalibrated to a specific operating time. In order to maintain approval for the device, the MID (Measuring Instruments Directive) recommends recalibrating gas meters after eight years or in accordance with national regulations. To do this, SICK offers both a standard and a premium package containing additional options, as well as a current firmware update. In addition, SICK inspects and cleans the ultrasonic gas meters to test that they are fully functional. SICK supports customers with customized packages. This saves time and resources.
