    Caution! Calibration must be performed by qualified personnel. Spirax Sarco strongly recommends that you return your flowmeter to the factory for calibration. In order to achieve accurate and repeatable performance, the flowmeter must be installed with the specified minimum length of straight pipe upstream and downstream of the flowmeter’s sensor head.

  • Page 8: Intended Use

    Determine the correct installation situation and direction of fluid flow. iv) Spirax Sarco products are not intended to withstand external stresses that may be induced by any system to which they are fitted. It is the responsibility of the installer to consider these stresses and take adequate precautions to minimise them.
