    摘要： The present disclosure relates to a method for acoustic leakage detection in a fluid pipe network (1) by use of at least one ultrasonic flow meter (13) installed at a pipe (15, 17), wherein the pipe (15, 17) connects a consumer site (3) to the fluid pipe network (1), the method comprising:
    - detecting at least one sound wave travelling along the pipe (15, 17) and/or along fluid within the pipe (15, 17) from a sound source to the at least one ultrasonic flow meter (13),
    - determining the travelling direction of at least one of the at least one sound wave,
    - interpreting a sound wave of said at least one sound wave as a leakage sound candidate if the determined travelling direction of said sound wave is towards the consumer site (3), and
    - interpreting a sound wave of said at least one sound wave as a background noise if the determined travelling direction of said sound wave is away from the consumer site (3).

    摘要： A turbidity measurement device for measuring turbidity of a fluid flowing in a flow tube. A first transducer transmits ultrasonic signals through the fluid in the turbidity measurement section so as to provide a first ultrasonic standing wave between the first and second section ends. A receiver transducer receives the ultrasonic scattered response from particles in the fluid flowing through the turbidity measurement section. A control circuit operates the transducers and generates a signal indicative of the turbidity of the fluid in response to signals received from the receiver transducer. Preferably, the device may comprise a second transducer for generating a second ultrasonic standing wave with the same frequency, and further the two transducers may be used to generate a measure of flow rate by means of known ultrasonic techniques. This flow rate may be used in the calculation of a measure of turbidity. Both turbidity facilities and flow rate facilities may be integrated in a consumption meter, such as a heat meter or a water meter.
