Fluid meter with a fluid housing and a method for manufacturing the fluid housing, which comprises a fluid inlet, a fluid outlet and a fluid channel, which extends between the fluid inlet and the fluid outlet and which is fluidically coupled to the fluid inlet and the fluid outlet, wherein the fluid housing has a side facing the fluid channel, to which a fluid-measuring module is assigned, which is in direct contact with a fluid flowing through the fluid channel at a fluid-side interface, wherein the fluid-measuring module is surrounded by the fluid housing, and wherein the fluid-measuring module is equipped to generate surface acoustic waves which propagate along the fluid-side interface of the fluid-measuring module.
ELECTROMAGNETIC INTERFERENCE RESISTANT ELECTRONICS ENCLOSURE
An EMI resistant electronics enclosure (200) is provided having a first compartment (206) and a second compartment (207), each defined by a body (205), being separated by a septum (208). A first aperture (209) in the septum (208) connects the first compartment (206) and the second compartment (207). A feed-through element (210) is provided having a first interface region (211) and a second interface region (212), wherein one or more primary conductors (217) extend between the first interface region (211) and the second interface region (212), and wherein the first interface region (211) resides in the first compartment (206), and the second interface region (212) resides in the second compartment (207). A conductive bar (232) circumscribes at least a portion of the feed-through element (210), and a conductive gasket (220) extends from the body (205) to the conductive bar (232), wherein a ground path is formed between the body (205) and the conductive bar (232) with the conductive gasket (220).
ULTRASONIC METER
The invention relates to an ultrasonic meter for measuring a flow rate or flow volume, comprising a fluid inlet, a fluid outlet and a flow channel arranged between the fluid inlet and the fluid outlet, two ultrasonic transducers and at least one reflector for ultrasonic signals.
To create an ultrasonic meter according to the preamble, in which fluid flow through the flow channel is, as far as possible, undisturbed in order to achieve an undistorted measurement result, it is proposed within the framework of the invention to arrange ultrasonic transducers outside the flow channel, wherein entrance and exit openings for ultrasonic signals, each running obliquely relative to the longitudinal axis of the flow channel, are provided between the ultrasonic transducers and the flow channel, and to arrange the reflector on the wall of the flow channel opposite the entrance and exit openings such that it reflects ultrasonic signals of the ultrasonic transducers.
By mounting the ultrasonic transducers outside the flow channel and arranging the reflector in the region of the wall of the flow channel, it is ensured that the passage of liquid through the flow channel is not disturbed by these elements. A distortion of the measurement result is thereby avoided.
