Abstract: A consumption meter arranged to measure a flow rate of a fluid, the consumption meter comprising: a tube with two transducer holes in a wall of the tube; a meter housing arranged at the tube, comprising two transducer housings and a main housing; first and second ultrasonic transducers arranged in the transducer housings and arranged for transmitting and receiving ultrasonic signals propagating through the fluid; a control circuit arranged in the meter housing for operating the first and second ultrasonic transducers, and being arranged to generate a signal according to the flow rate of the fluid. wherein the transducer housing comprises: an internal transducer housing element arranged at an inner surface of the tube and an external transducer housing element arranged at an outer surface of the tube. The internal transducer housing element and/or the external transducer housing element are arranged to extent through the transducer hole in the wall of the tube and to engage. Whereby the transducer housing is fixated to the tube. The main housing is arranged to engage with the transducer housing to constitute a closed meter housing.

Abstract: 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.

Abstract: An ultrasound flow meter unit, e.g., a unit forming part of a flow meter for ultrasonic measurement of a fluid flow. The unit comprises two ultrasound transducers 206, a circuit board 202 with an electronic circuit 204 arranged for operating the ultrasound transducers 206, and a common protection membrane 132, such as a sheet of metal, for protecting the transducers 206. The common protection membrane 132 forms part of a water-tight casing, such as an IP68 class casing. The two ultrasound transducers 206 and the circuit board 202 with the electronic circuit 204 are positioned within the water-tight casing and thus protected against damaging humidity. A glass sealed feed-through 128 can be used to provide external electrical contact to the electronic circuit 204, i.e. for outputting an electric flow rate signal. Such flow meter unit is highly versatile within many applications since it provides a compact and robust unit. The unit can be used with or integrated in many types of devices, e.g. flow meters, such as used in consumption meters for charging purposes or in many other industrial or home applications.
