A method monitors an operation of a fluid meter mounted in a fluid-supplying fluid distribution system. Wherein, by use of an ultrasonic transducer, an event, in the form of a noise generated during the operation of the fluid meter or a pressure surge generated in the distribution system, which is not attributable to the flow measurement and which mechanically excites the ultrasonic transducer, is selectively detected and evaluated and, by reference to a result of the evaluation, at least one fluid meter-specific operating property is generated.

Method for monitoring the operation of a fluid meter and fluid meter

An ultrasonic fluid meter for determining the flow rate and/or volume of a flowing medium includes a housing, an inlet, an outlet, a first ultrasound measurement path including at least one ultrasound transducer, and a second ultrasound measurement path including at least one ultrasound transducer. The ultrasound measurement paths extend at an angle to one another inside the housing and intersect. The first ultrasound measurement path and the second ultrasound measurement path extend at an angle to one another and intersect in a common region, as seen in a projection plane of a flow cross section. A method for determining the flow rate and/or volume of a flowing medium is also provided.

Ultrasonic fluid meter and method for determining the flow rate and/or volume of a flowing medium

An ultrasonic transducer arrangement has a housing for mounting the ultrasonic transducer arrangement in a through-hole in a housing of an ultrasonic water meter in a mounting plane. The housing of the meter contains an ultrasonic measuring section along which a transit time measurement can be carried out by the ultrasonic transducer arrangement. The ultrasonic transducer arrangement has a transducer body located in the housing for generating and/or receiving an acoustic signal, a housing wall assigned to the transducer body through which the acoustic signal runs, and an electrical contact for connecting the transducer body to a voltage or current source. The transducer body is positioned in the housing at an oblique angle with respect to the mounting plane. A holding device, which is oriented at an oblique angle with respect to the mounting plane is provided inside the housing, which exerts a holding force oriented towards the housing wall.

Ultrasonic transducer arrangement and ultrasonic water meter

The present invention relates to an ultrasound transducer assembly for an ultrasound flowmeter, comprising a one-part or multi-part housing (), which is provided to be connected to a line carrying the medium to be measured, wherein the ultrasound transducer transmits ultrasound through the housing () and the ultrasound transducer assembly has the following features:

Ultrasound transducer assembly and ultrasound flowmeter

The present invention relates to a measurement insert for a flow meter and a flow meter. The present invention discloses using, in a customary housing of a bulk water meter, e.g. a Woltman meter, instead of a device for mechanical flow measurement a measurement insert which comprises an ultrasonic measurement path and can be fastened to the opening of the housing by a housing cover.

Retrofit ultrasonic insertion type flow meter

The present invention relates to a housing arrangement for an ultrasound flow meter, comprising a unipartite or multipartite housing () provided to be connected to a fluid line, comprising an ultrasonic transducer having an ultrasonic transducer body and a housing or covering which at least partially surrounds the ultrasonic transducer body, comprising a housing opening provided in the housing () for positioning the ultrasonic transducer at the housing arrangement, comprising a sealing element arranged between the housing () and the ultrasonic transducer, wherein a housing insert () can be inserted in the housing opening () as a module, the housing insert () is adapted to receive at least two ultrasonic transducer bodies () which are positioned separately, without the ultrasonic transducer body () coming into contact with the fluid, and the housing insert () is connected to the housing () via a sealing element () which is common to the ultrasonic transducer bodies () which are positioned in the housing insert (). The present invention furthermore relates to an ultrasound flow meter with a corresponding housing arrangement.

Housing arrangement for ultrasound flow meter and ultrasound flow meter

The invention relates to a flow meter for liquid or gaseous media, the flow meter has a measuring channel through which the medium flows, at least one inlet channel and at least one outlet channel and also at least one pair of ultrasound converters for emitting and receiving ultrasound signals, wherein for guiding an ultrasound signal from one ultrasound converter to the other ultrasound converter, at least one pair of reflectors is arranged in the measuring channel, the diameter of the measuring channel is reduced using a reducer in certain regions for guiding the flow of the medium, wherein the reducer is formed by a measuring channel insert, which is arranged on and/or integrated into the measuring channel inner wall, and which is used simultaneously for holding or fixing other functional parts. Furthermore, the invention relates to a flow meter, in which a flow guide plate is used as a holding plate for the pair of reflectors and stretches in the longitudinal direction of the measuring channel. In another embodiment at least two measuring sections each having at least one pair of reflectors and one pair of ultrasound converters are provided.
