    摘要: A test stand (100) for calibrating and/or testing a flow meter for a liquid (T), comprises:
    a) a test line (101) for installation of a flow meter to be tested (T), whereby the test line (101) comprises a supply line (112) for supplying a test liquid to the flow meter to be tested (T) and a discharge line (113) for discharging the test liquid after exiting the flow meter to be tested (T);
    b) a liquid supply device (111) for delivering the test liquid through the supply line (112);
    c) a measuring device (120) for determining a quantity, especially a mass and/or a volume, of test liquid flowing through the flow meter to be tested (T);
    characterized in that
    d) the test stand comprises a heating device (130) for increasing the temperature of the test liquid before entering the flow meter to be tested (T), and a cooling device (140) for reducing the temperature of the liquid after exiting the flow meter to be tested (T).

    摘要: The present disclosure is directed towards a method of controlling opening of a valve (10) in an HVAC system (100). The method includes controlling the opening of the valve (10) according to a default control mode in dependence of a default sensor signal. The method further includes determining, while controlling the opening of the valve (10) according to the default control mode, whether the default sensor signal is faulty and switching, in case of the default sensor signal being faulty, to controlling the opening of the valve (10) according to a fallback control mode, with the opening of the valve (10) being controlled independently of the faulty sensor signal in the fallback control mode. The present invention is further directed towards a corresponding control device opening of a valve (10) in an HVAC system as well as a corresponding computer program product.
